Tonle Sap Lake, Siem Reap Overview

The Tonle Sap is the largest freshwater lake in South East Asia, located near Siem Reap in Cambodia. Located in the lower Mekong Basin, Tonle Sap is a part of Tonle Sap river formed from the Mekong river. It is known for its rich ecosystem and many floating villages. Stretching from Angkor Wat to Phnom Penh, this vast lake serves as a home to more than 1.2 million people along with being the source of food and livelihood.

Known popularly as the 'Great Lake,' its varying size is a beautiful phenomenon. The lake swells to become one of the largest in Asia spreading for over 10,000 square kilometres in the wet season submerging forests around. And during the dry season, it shrinks drastically, reducing to just 3000 square kilometres, which bring the dense forests above water making the land fertile.

You can go on a day trip from Siem Reap to some of the floating villages located on Tonle Sap, where you can get to see the unique life of the villagers amidst a vibrant landscape.

You might feel rushed through boat tours which are quick and will not let you experience the place.
  • Kompong Phluk - The other villages are worth visiting although they are far and a bit difficult to reach. One of them is Kompong Phluk, a Khmer village consisting of stilted houses and buildings. It is bigger than Chong Khneas, and more beautiful and less touristy, making it an ideal option for a day trip from Siem Reap.
