🛶 Top Things to Do at Tonle Sap Lake

1. Explore Floating Villages

Visit communities where homes, schools, shops, and even temples float on rafts or are built on stilts above the water. Daily life adapts with the seasons—fishermen cast nets from their doorsteps, and children paddle canoes to school.

Notable Villages:

Kompong Phluk – Known for its tall stilt houses and serene flooded forest

Kompong Khleang – Largest village with an authentic, less-commercialized atmosphere

Chong Khneas – Touristy but good for first-time visitors

2. Take a Boat Tour Through the Flooded Forest

During the wet season, flooded mangrove forests surround Kompong Phluk. Paddle a small boat between submerged trees and listen to the birdsong—it's like entering another world.

Dry season tip: Visit early in the year to still catch partially flooded areas.

3. Visit the Prek Toal Bird Sanctuary

Located on the lake’s northwest corner, Prek Toal is a UNESCO Biosphere Reserve and one of Southeast Asia’s most important bird sanctuaries.

Expect to see:

Spot-billed pelicans

Painted storks

Black-headed ibises

Egrets and darters

Best visited between December and February when water levels are lower and birds gather in large numbers.

Some communities like Mechrey offer homestays or guided eco-tourism programs. This is a fantastic way to:

Support local livelihoods
