Mondolkiri is the largest province of Cambodia but is sparsely populated with about 40,000 people. Located on the eastern highlands, Mondolkiri has scenery and a climate quite unlike anywhere else in the country. There are rolling grassy hills, serene rivers, powerful waterfalls, and forested mountains. At an average elevation of 800m, it can get quite chilly at night. Mondulkiri has numerous tourist attractions such as waterfalls, indigenous hilltribe culture, national parks and elephant trekking. Sen Monorom, the provincial capital, is a quiet town with a frontier feel, although it has potential to develop into an eco-tourism center.
