Lake Tonlé Sap is the largest freshwater lake in Southeast Asia and can be found in Cambodia. Its name translates to 'Great Lake' and belongs to the Mekong River Delta. Many of the 1.2 million residents of the lake live in floating villages working as fisherman, most of which are of Vietnamese descent. Day trips to Tonlé Sap can be organized from Penom Penh.

Southeast Asia typically refers to the peninsular region in Asia comprising the countries of Cambodia, Laos, Vietnam, Myanmar, Thailand, and West Malaysia, though it is often known to include many small islands in the region as well. All countries comprise about 8.5% of the world's population and 3% of Earth's total land area. SE Asia is the most culturally diverse region of the world.

Penon Penh and Siem Reap are the two must sees in Cambodia. The country is most well known for its collection of temples, in their highest concentration at Angkor Archeological Park (near Siem Reap). Here you can see world famous temples such as Angkor Wat, Angkor Thom, Bayon, Phnom Bakheng, Pre Rup, Preah Khan, and Temple Ta Prohm.
