Tonle Sap Lake

The Tonle Sap is a very large river, which at one point becomes as wide as a lake. Traveling along this river is an interesting way to reach Siam Reap from Pnomh Penh. While the slow boats take a couple of days to make the journey, it is easy to find fast boats which take only half a day. It is preferable to arm oneself with sunscreen and sit on the top of the boat (which will be overcrowded), to get a better view, more fresh air, and improve your chances of survival should the boat capsize
Life on the great lake has always required people to adapt to the strong seasonal fluctuations in water levels and currents.
