Tonle Sap Lake from Siem Reap: Seasons, Villages, Boats and the Tours to Avoid (2026)

The Tonle Sap is the same lake in April and in October and it is not the same trip. Between those two months the water surface grows roughly fivefold, from about 2,500 square kilometers to as much as 16,000, and the level rises 8 meters or more. A village that stands on bare mud at the end of a shrinking channel in April is standing in open water with boats moored at its front steps by October. The question most travelers type, whether the floating village is worth visiting, has no single answer. It has a month and a pier.

The search results for that question are dominated by tour listings that quote a price without saying which village, and by reviews written at Chong Kneas, the pier nearest to town, where the boats have been run by the state ticket company since 2022 and the circuit still includes a floating shop, a crocodile pen and a sack of rice. Almost none of them explain that Kampong Phluk, an hour away, is run by its own community office, or that Kampong Khleang, 90 minutes east, is a town of several thousand families that sees a fraction of the visitors. Fewer still say what the lake looks like in March.

This guide explains the pulse of the lake month by month, compares the five places where a boat can be hired, separates what floats from what stands on stilts, names the scams and sets out how to organize the half day with a tuk-tuk, a car or a guide. Prices, hours and transport times below were checked against operator websites and official sources in October 2026.

The Lake Is Not One Place, It Is Two Seasons

Every other decision follows from this one. The Tonle Sap is a flood-pulse lake: for about six months a year the Tonle Sap River drains it toward the Mekong at Phnom Penh, and for the other six months the swollen Mekong pushes water back up the same river and fills it. The reversal usually begins in May or June and ends in October or November, and the three-day Water Festival in Phnom Penh, Bon Om Touk, marks the moment the river turns back toward the sea.

What this means for a visitor is simple. In the high-water months, roughly August through January, a boat leaves the pier and is on the lake within minutes, the stilt villages stand in water, the forest is flooded to the canopy and the bird colonies at Prek Toal are feeding and breeding. In the low-water months, roughly March through June, the same boat spends half an hour in a muddy channel, the villages stand on dry ground, the forest is a wood you could walk through and parts of the lake are too shallow to reach.

The two seasons also change which village is worth the drive. In October, Kampong Phluk is the right half day for almost everyone. In April, Kampong Phluk is a long drive to look up at stilts, and Kampong Khleang, whose scale survives the dry season better, is the better use of a morning. Chong Kneas is the wrong answer in both.

How the Pulse Works, Month by Month

The figures below are planning estimates for a normal year. The last few years have not been normal: the reverse flow started six weeks late in 2025 and was far below average in volume, and in 2024 the accumulated reverse flow stood at about 18 cubic kilometers in early September against a long-term average several times higher. Upstream dams on the Mekong hold water during the wet season to fill their reservoirs, and the lake’s rise now comes later and lower than it did a decade ago. If your trip is in August or September, expect conditions closer to what the table shows for a month earlier.

Month	Water	What a boat trip gives
November	Falling from peak, still high	Villages in water, forest flooded, Prek Toal season opens, clear skies after the rains
December	High, falling slowly	The best all-round month: full villages, paddle boats running, peak bird numbers
January	High to medium	Still good everywhere. Last reliable month for the forest paddle
February	Falling fast	Villages begin to stand clear of the water. Prek Toal access closes toward the end of the month
March	Low	Long channel rides, dry forest, houses on full stilts. Kampong Khleang holds up best
April	Lowest	Lake at roughly a fifth of its peak size, piers moved toward the water, heat above 35 C
May	Low, reversal beginning	Rains start, water still low, the mud is deep at the piers
June	Rising slowly	Villages still above water. Not yet worth the trip for the lake itself
July	Rising	Water reaching the lower stilts at Kampong Phluk, forest floor flooding
August	Rising fast	Forest paddle usually possible again, villages filling
September	Near peak	Open water from the piers, afternoon storms, few tourists
October	Peak	Lake at its largest, houses within a meter of the water, the strongest month for photographs

Two notes on the table. The lake’s rise lags the rain: Siem Reap’s wettest months are September and October, the lake peaks around the turn of November and it is still high in December when the town is dry. And the receding lake moves the piers. At Kampong Phluk, Mechrey and Chong Kneas the ticket office stays put while the boarding point shifts south, which adds a dirt-road stretch in March and April and is one reason dry-season tuk-tuk drivers ask for more.

The Five Villages Compared

Five places near Siem Reap sell a boat onto the lake. They are listed from nearest to farthest. Every one of them is outside the Angkor Archaeological Park and none is covered by the Angkor Pass.

Chong Kneas

The honest verdict: skip it unless it is the only lake you will see. Chong Kneas is 15 km south of the Old Market on a sealed road that passes the foot of Phnom Krom, about 25 minutes by tuk-tuk at $3 to $4 one way. Since February 2022 the tourist boats have been managed by Angkor Enterprise, the state company that sells the Angkor Pass, which replaced a community association of about 110 families and roughly 300 boats. Tickets are sold only at the Tonle Sap Lake Ticket Center by the pier, not online, according to Angkor Enterprise’s boat ride page: $28 for a boat carrying up to 5 passengers, $38 for up to 8, then $70, $90 and $120 for medium boats up to 14, 19 and 25 passengers, and $150 and $180 for large boats up to 35 and 42. The price is per boat, so two people pay $28 and a group of eight pays $38. The trip lasts about two hours, following the channel to the lake, circling the floating section and stopping at a floating shop. In high water the village is a true floating village: houses, a school, a church and shops on bamboo and drum rafts that are towed to new positions as the water moves.

The limitation is everything around the boat. The ticket system stabilized the price but the circuit still delivers passengers to the floating shop where rice is sold for the school, to a crocodile pen attached to a souvenir counter, and to a floating restaurant with a 300 percent markup on a can of Coke. Google reviews run at about 2 out of 5 across more than 1,200 ratings. The one asset nobody can take from Chong Kneas is Phnom Krom above it, covered below.

Kampong Phluk

The honest verdict: the right half day for most visitors between August and January, and a reasonable one in February. Kampong Phluk is a commune of three villages in Prasat Bakong District, about 3,700 people in 911 families at the 2019 census, around an hour from Pub Street by tuk-tuk. The route runs east on National Road 6 toward the Roluos temples, then south on a sealed road to the ticket office, with the final stretch to the pier unpaved and longer in the dry season. The community ticket office, run by Kampong Phluk Eco Tourism management, charges $20 per person for the motorboat and a $2 per person community fee, and $5 per person for the paddle boat into the flooded forest when the water allows. Boats belong to village families and take turns through a queue, so the fare goes to the village rather than to an agency. The houses stand on hardwood stilts 6 to 9 meters high. In October the water is within a meter of the floors and boats tie up at the staircases. In April the stilts are fully exposed and the main street is dry earth.

The limitation: Kampong Phluk is the village the guides moved to when the Chong Kneas system changed, and it now handles around 80 boatloads a day in season against 30 to 40 at Chong Kneas. Late afternoon, when the sunset tours arrive together, the channel is a procession. Go at 7:30 a.m. or at 2:00 p.m. and it is a different place. The forest paddle is also sold whether or not the water is high enough to make it worthwhile.

Kampong Khleang

The honest verdict: the best village on the lake and the one that needs the most time. Kampong Khleang is 50 to 55 km east of Siem Reap, about 75 to 90 minutes by car along National Road 6 past Dam Dek and then south to the water, or closer to two hours by tuk-tuk on a road that is fine in the dry season and slow after rain. It is the largest settlement on the Tonle Sap, variously counted at around 1,000 families in the stilted town or up to 20,000 people across the commune, with a pagoda, schools, a market and a separate floating section on the open lake that moves with the water. The stilts are taller than Kampong Phluk’s, and at the end of the wet season the house floors sit less than a meter above the water while in the dry season the drop to the water is several meters. The boat takes 20 to 30 minutes through the town to the floating houses and the lake. There is no flooded-forest paddle here.

Prices are the weak point of the information. No fare is posted at the jetty. Visitors reported paying $25 per person for the boat in April and July 2025, 2026 reports give $20 to $25, and a group of five negotiated $55 for one boat in August 2025. A July 2025 visitor who came by motorbike without taking a boat was charged $15 to enter. Expect $20 to $25 per person if you arrive independently, and agree on the price before boarding. The limitation: this is a working town, not a circuit built for visitors. There are no signs, few people speak English and at the very lowest water in April and May the boat may not reach the floating section at all. A full day that pairs Kampong Khleang with Beng Mealea or the Roluos group is the usual way to justify the distance.

Mechrey

The honest verdict: the quiet near option, and the pier for Prek Toal. Mechrey sits on the northwest shore about 30 minutes from town along the road toward the airport and then south past Wat Mechrey, a floating pagoda, on a sealed road to the pier. The community ticket office charges by boat: $19 for a small boat of up to 8 passengers, $35 for 9 to 15, $40 for 16 to 22, $45 for 23 to 32 and $55 for 33 to 45, plus a $2 per person tourism fee. The two-hour trip follows a marsh-lined canal to the Sangker River and past the northern and southern floating sections. Tour groups are few because the agencies have no circuit here. The limitation: the circuit includes a crocodile farm stop, there is no flooded forest to paddle, and Mechrey’s floating houses are a smaller version of what Kampong Khleang offers. It makes most sense as the launch point for a kayak or birding trip, or for a traveler who wants two hours on the water without an hour of road first.

Prek Toal

The honest verdict: the best nature experience within reach of Siem Reap, for people who will get up at 5:00 a.m. for birds. Prek Toal is both a floating village at the mouth of the Sangker River in Battambang Province and a 21,342-hectare core zone of the Tonle Sap Biosphere Reserve, a Ramsar site since 2015 and the largest waterbird colony in Southeast Asia. Getting there is a day: a car to Chong Kneas or Mechrey, a motorboat of about an hour across the open lake to the Ministry of Environment station at the village, then a smaller boat an hour into the flooded forest to a viewing platform among the nests. A boat from Chong Kneas to the environment station runs about $55 return and the small sanctuary boat about $30 including a ranger guide. The Ministry of Environment does not publish the sanctuary fee online. Travel guides updated in 2025 and 2026 quote $20 to $35 per person, some with the guided sanctuary boat included, so ask what a quote covers. Two Siem Reap organizations have run the trip for two decades. Osmose, an NGO at House 0203 in Wat Damnak, employs former egg collectors as guides and offers half-day, full-day and overnight tours with a $35 to $60 per person birdwatching supplement and a $15 French-speaking guide fee, with base prices on request. Sam Veasna Conservation Tours, the registered company that grew out of the Sam Veasna Center, lists an 11.5-hour Tonle Sap Waterbirds and Floating Village day at $295 including guide, boats, fees, breakfast, lunch and binoculars, and runs it November to March.

The limitation is the season and the price. From late February the water drops too far for boats to reach the colony, and the day costs more than a week of temple tuk-tuks. Full details of the species, the start time and how to book are in the Prek Toal bird sanctuary guide.

Floating or on Stilts: What You Are Actually Looking At

The phrase “floating village” is applied to all five places above and is accurate for about one and a half of them. The distinction matters because it decides what the dry season does to your visit.

Floating means a house on a raft of bamboo, oil drums or timber, moored in open water and towed to a new position as the lake rises and falls. Chong Kneas is a floating village in this sense, as are the lake sections of Kampong Khleang, Mechrey and Prek Toal. A floating house is always at water level, so a floating village looks much the same in April and October, except that in April it has been towed kilometers out to where the water still is, and the channel to reach it is long and muddy.

On stilts means a fixed house on hardwood posts set into the lake bed, 6 to 9 meters high at Kampong Phluk and higher at Kampong Khleang. The house never moves. The water does. In October the lake reaches the staircase and the village is a town of boats. In April the same village is a town of ladders, with motorbikes parked on the ground where boats were moored five months earlier. The stilted villages are the ones whose character changes with the season, and they are the ones most people mean when they ask whether the trip is worth it.

The practical consequence: a stilted village in high water is the postcard. A stilted village in low water is an architectural curiosity and a short boat ride. A floating village floats in any month, which is the case for Kampong Khleang’s lake section and the reason it is the dry-season choice.

The Flooded Forest

The forest ringing the Tonle Sap is a seasonally flooded woodland of short, dense trees, called mangrove by boat operators although it is a freshwater forest with no mangrove species in it. At Kampong Phluk the paddle-boat excursion enters this forest from the main channel: a woman from the village paddles a wooden boat of two to three passengers for 20 to 30 minutes under a canopy that in October stands in 3 to 5 meters of water, trunks submerged and the light coming through leaves at eye level.

The paddle is sold at $5 per person at the Kampong Phluk ticket office when the water allows, which in a normal year means roughly August through January. In early February the water is dropping below the branches. By March the forest floor is exposed and the excursion stops. If the forest is your reason for coming, do not book Kampong Phluk between March and July.

The same forest is what the Prek Toal colony nests in. The storks, pelicans and cormorants build in the tops of the same trees, which is why their season and the forest’s are one season.

The Birds of Prek Toal and When to Go

Prek Toal supports the largest breeding colonies of large waterbirds in Southeast Asia and more than 150 recorded species. The ones people come for are the Greater Adjutant and Lesser Adjutant, two storks over a meter tall whose global populations are small enough that the Prek Toal colony counts for a meaningful share, plus the Spot-billed Pelican, Milky Stork, Painted Stork, Asian Openbill, Oriental Darter, Great and Indian Cormorant and the Grey-headed Fish Eagle. Rangers, several of them former egg collectors paid to protect the nests they once raided, staff platforms built into tall trees, and the viewing is from those platforms with binoculars.

The season is set by the water. Nesting begins as the lake starts to fall in November, when the fish concentrate and the trees are still deep in water. December to February is the peak, with the most birds and the most reliable boat access. The colony stays busy into April, but from late February the small boats cannot reach the platforms and the trip is off. September and October are possible for the lake itself, with far fewer birds. Mornings are better than afternoons for activity and for the heat, which is why every operator leaves Siem Reap between 5:00 and 6:00 a.m.

The Scams, Named

The scams of the Tonle Sap are concentrated at Chong Kneas and are known well enough to describe precisely. They are also on the Siem Reap scams to avoid list, where they share a page with the milk scam of the Old Market, which works the same way.

The rice for the school. The boat stops at a floating shop. On a shelf are sacks of rice at $30 to $50, three to five times the market price. The guide or driver explains that the floating school nearby needs rice, and that visitors buy a sack to donate. The sack is carried to the school, and then carried back to the shop to be sold to the next boat. The school may exist. The rice is a loop. Decline it, and if you want to support a school near the lake, the social enterprises in Siem Reap list organizations with published accounts.

The crocodile farm. A floating platform with a pen of crocodiles kept for skins and a souvenir counter above it. It is presented as a traditional industry of the lake, which in a small way it is, but the stop exists to deliver you to the counter. There is no obligation to buy anything or to pay for the crocodiles. Mechrey’s circuit has a similar stop.

The donation. On the boat, the driver or a child who has climbed aboard from a passing dinghy asks for money for the school, for an orphanage or for the children. This is the one that works on people who have declined the first two. The honest response is the same one given in the orphanage tourism guide: giving money to a child on the water is what keeps the child on the water tomorrow instead of in a classroom.

The overpriced boat. Less a scam than a pattern. A tuk-tuk driver who proposes the floating village on the way back from the temples takes a commission, and the boat he arranges costs more than the posted price at the pier. Buy the ticket at the counter yourself and pay the driver only for the driving.

At Kampong Phluk and Kampong Khleang these pitches are uncommon. The $2 community fee at the Kampong Phluk office is the only contribution asked, and it goes to the village’s tourism organization, which supports elderly and sick residents.

Phnom Krom: The Hill Above the Pier

The one part of a Chong Kneas trip that nobody regrets is the hill the road passes on the way. Phnom Krom is a 140-meter outcrop 12 to 13 km south of the Old Market, with a late-ninth-century temple of three brick-and-sandstone towers on its summit built under Yasovarman I and dedicated to Shiva, Vishnu and Brahma, the same king and the same plan as Phnom Bakheng and Phnom Bok. From the west gate the view is the lake, which in October is water to the horizon and in April is a plain of green and brown with a silver line far to the south. Siem Reap and the wheel of the Angkor Eye are visible to the north and Phnom Kulen beyond.

It is an Angkor-period site, and that means the Angkor Pass is required: a checkpoint on the staircase about halfway up checks it and turns away people without one. The site is open 6:00 a.m. to 7:00 p.m., and the only sensible times are before 8:00 a.m. and after 4:30 p.m., because the climb is in full sun. Almost nobody goes. The sunset here is quieter than any inside the park, and the hill is 20 minutes by tuk-tuk for $4 to $5 one way, with or without a Chong Kneas boat. The limitation: the temple is small and ruined, and a hazy March evening gives a view of dust. The Phnom Krom sunset guide covers the timing month by month.

How to Organize the Half Day

Four ways to do it, from cheapest to most structured. Whichever you pick, carry small dollar bills and riel: the ticket offices give change in riel under $1 and refuse torn notes, as explained in the dollars and riel guide.

Tuk-tuk, independently

The default for Chong Kneas and Kampong Phluk. Agree on a wait-and-return price before leaving. Chong Kneas is $3 to $4 each way with the wait negotiated, and one Siem Reap agency lists the round trip at $13 on its 2026 tuk-tuk price list. The Kampong Phluk half day runs $20 to $25 in 2025 and 2026 reports. Buy the boat ticket yourself at the counter. Leave Pub Street at 2:00 p.m. for a 3:00 p.m. boat and a return before dark, or at 6:30 a.m. for the cool, empty morning version. A tuk-tuk to Kampong Khleang means two hours each way in an open cab on National Road 6, and the same agency lists the day at $34. General rates are in getting around Siem Reap.

Car with driver

The right choice for Kampong Khleang and for anyone traveling with children or in April heat. A car and driver for a half day to Kampong Phluk costs $35 for an SUV and $45 for a minivan on one Siem Reap driver company’s published rates, boat tickets not included. Kampong Khleang has no published rate, and a June 2025 report gives $35 to $60 for a car to Kampong Khleang or Mechrey. Book through the hotel desk or any driver who works the temple circuit. The driver waits at the pier. Combining Kampong Khleang with Beng Mealea or the Roluos group makes a full day of $80 to $100 for the vehicle.

Shared tour

Shared minivan tours to Kampong Phluk sell from $18 to $40 per person, mostly for the sunset slot. At the low end the price does not include the $20 boat ticket and $2 fee, which is how a tour can cost less than the ticket, and the group arrives in the channel with every other sunset tour. At the higher end the ticket is included and the group is smaller. Read the inclusions line before paying.

Private guided tour

A guide adds explanation, which at a stilted village with no signs is worth more than at a temple with a guidebook. Private half-day tours to Kampong Phluk with guide, vehicle and tickets run about $60 to $90 per person for two. For Prek Toal a guided tour is the only practical option, with Osmose and Sam Veasna Conservation Tours the two specialists, at $130 to $300 per person depending on group size. The reasoning in hiring an Angkor guide applies to the lake as well.

Bicycle or quad

Chong Kneas and Phnom Krom are reachable by bicycle along a flat 15 km road through rice fields, best before 8:00 a.m., described in the cycling routes guide. Several quad operators run sunset routes toward the lake shore and Phnom Krom without a boat, covered in quad biking around Siem Reap. Neither reaches Kampong Phluk comfortably.

By Situation

You have half a day and it is between August and January

Kampong Phluk, by tuk-tuk from Pub Street at 2:00 p.m. or 6:30 a.m., $22 in tickets plus $5 for the forest paddle. This is the best version of the trip and the one that answers the question in the title with a yes.

You have half a day and it is between March and June

Kampong Khleang by car, early, and accept that the forest is off. The stilted town holds its interest when dry, and its floating section is on the lake in every month. If Kampong Khleang is too far, Phnom Krom at sunset without a boat gives the lake from above for the price of the pass you already hold.

You want birds

Prek Toal between December and February, with Osmose or Sam Veasna Conservation Tours, leaving town at 5:30 a.m. Nothing else on the lake compares, and nothing else costs as much. Pair it with the rest of the nature around Siem Reap only if you have a week.

You are traveling with children

Kampong Phluk in high water, by car rather than tuk-tuk, in the morning. The paddle through the forest is the part children remember. Avoid Chong Kneas: the crocodile pen and the rice pitch are hard to explain and the boat ride is long for the payoff. More on timing the day in Siem Reap with kids.

You have no interest in boats but want the lake

Phnom Krom at 5:00 p.m. with the Angkor Pass. Twenty minutes by tuk-tuk, 15 minutes of stairs, the whole lake from 140 meters.

Your hotel desk or tuk-tuk driver has proposed “the floating village” for this afternoon

Ask which one. If the answer is Chong Kneas, ask for Kampong Phluk instead and expect the price to rise from about $13 to about $22 for the tuk-tuk. That difference is the whole difference between the two trips.

What It Actually Costs

All prices in US dollars, which every ticket office accepts. Riel change is given under $1. Boat prices at Chong Kneas and Mechrey are per boat, at Kampong Phluk per person.

Item	Price	Notes
Chong Kneas boat, up to 5 people	$28	Angkor Enterprise, per boat, about 2 hours
Chong Kneas boat, up to 8 people	$38	Larger boats $70 to $180
Kampong Phluk motorboat	$20 per person	Community ticket office, about 1 hour
Kampong Phluk community fee	$2 per person	Goes to the village tourism organization
Kampong Phluk paddle boat, flooded forest	$5 per person	August to January only
Kampong Khleang boat	$20 to $25 per person	Nothing posted, agree at the jetty. $15 entry without a boat
Mechrey boat, up to 8 people	$19	Plus $2 per person tourism fee
Prek Toal sanctuary entrance	$20 to $35 per person in 2025-2026 guides	Not published by the Ministry of Environment. Some quotes include the sanctuary boat
Prek Toal boats from Chong Kneas	$85 per boat for 1 to 8 people on the Angkor Enterprise price list, plus a sanctuary boat of about $30 in older reports	Independent arrangement
Prek Toal guided day, Sam Veasna	$295 as listed	Guide, boats, fees, two meals, binoculars
Tuk-tuk to Chong Kneas	$3 to $4 one way	$13 round trip on one agency’s list
Tuk-tuk half day to Kampong Phluk	$20 to $25	About 1 hour each way
Car half day to Kampong Phluk	$35 SUV, $45 minivan	About 45 minutes each way
Car half day to Kampong Khleang	$35 to $60 in a 2025 report	75 to 90 minutes each way
Shared sunset tour to Kampong Phluk	$18 to $40 per person	Check whether the $22 in tickets is included
Phnom Krom	Angkor Pass required	$37 one-day pass, sunset entry after 4:45 p.m. on a pass dated for the next day

What is not included anywhere: a tip for the boat driver, usually $1 to $2 per boat, a tip for the paddle-boat rower at Kampong Phluk, drinks on the water and the wait time of your tuk-tuk, agreed in advance. What is never required: rice, a crocodile farm, a donation.

A full-cost example for two people at Kampong Phluk in November, by tuk-tuk: $22 for the tuk-tuk, $44 in boat tickets and fees, $10 for the forest paddle, $3 in tips. About $80 for the pair, for a four-hour afternoon. The same two people at Chong Kneas pay about $45, and get the circuit described above.

What Other Guides Get Wrong

1. Writing about “the floating village” as if there were one. There are five piers within 90 minutes of Siem Reap, run by four different organizations at four different price structures. A guide that does not say which village it means is describing Chong Kneas, because that is where the writer was taken.

2. Quoting a boat price without the month. The same $20 at Kampong Phluk buys an hour on open water in October and 30 minutes in a muddy channel in April. Any guide that says the trip is or is not worth it without naming a season is answering half the question.

3. Calling the stilt villages floating villages. Kampong Phluk and the town of Kampong Khleang do not float. Their houses are fixed on 6 to 9 meter posts, and the water comes to them. This is exactly why they look spectacular in high water and bare in low water, and a reader who expects floating houses in April is confused twice over.

4. Recommending the sunset tour as the only slot. The sunset at Kampong Phluk is sold by every agency, which is why the channel at 5:30 p.m. in December is a line of boats. The 7:30 a.m. version has the same houses, cooler air, working fishermen and nobody else.

5. Treating the rice for the school as charity. Many guides describe the stop neutrally or as a way to give back. The rice is resold. The useful advice is to decline it and, if giving matters to you, give to an organization that publishes accounts.

6. Calling the flooded forest a mangrove. The trees around the Tonle Sap are a freshwater seasonally flooded forest. There is no salt and no mangrove species. The distinction matters for one reason: a mangrove is flooded by every tide, while this forest is flooded for five months a year and dry for the rest, which is the whole reason the paddle boat runs only from August to January.

Detailed Guides

• Tonle Sap floating villages: Kampong Phluk vs Kampong Khleang vs Chong Kneas settles the three-way choice village by village, with the boat ride described minute by minute.
• Prek Toal bird sanctuary: season, cost and the 5 a.m. start decides whether the birding day is worth $130 to $300 and how to book it.
• Phnom Krom: the sunset hill nobody visits gives the month-by-month sunset times and the checkpoint rules for the Angkor Pass.
• Cycling around Siem Reap maps the flat ride to the lake shore and Phnom Krom and says when the heat makes it a bad idea.
• Quad biking in the Siem Reap countryside compares the operators and the dust on the sunset routes toward the lake.
• Angkor from above: balloon, helicopter and microlight covers the flights that show the lake and the floodplain from the air and what each costs.
• Elephants near Siem Reap: what ethical actually means sets the criteria for an elephant visit and applies them to the one forest near town.
• Siem Reap countryside tours sorts the rice-field and village tours into the staged and the real.
• Battambang from Siem Reap covers the other end of the lake, including the boat along the Sangker River past Prek Toal when the water is high enough to run it.

Where to Go Next

The lake is one of the two or three reasons to stay a day longer than the temples need, and how it fits into a stay is worked out in the three-day Siem Reap itinerary, which puts Kampong Phluk in the afternoon slot after a temple morning. The month you travel decides the version of the lake you get, and the best time to visit Siem Reap sets that against the heat, the rain and the crowds at Angkor. For the wider set of excursions that compete for the same half day, from Beng Mealea to the Kulen waterfall, the day trips from Siem Reap pillar ranks them by road time and reward, and for the one lake trip that is a full day rather than a half, Battambang from Siem Reap explains when the river boat runs.
