Mondulkiri (Khmer: មណ្ឌលគិរី, IPA: [mɔn ˌdɔːl ki ˈriː] literally: "Mountain of the Mandala.") is a province (khaet) of Cambodia. Bordering the provinces of Kratié to the west, Stung Treng to the northwest, Ratanakiri to the north and the country of Vietnam to the east and south, it is the most sparsely populated province in the country despite being the largest in land area. The province was created in 1961 from the eastern part of Kratié Province. The capital is the town of Senmonorom.

Mondulkiri is an eastern province of Cambodia, which is the most sparsely populated province in the whole country although being the largest province in Cambodia. The province is chock full of natural beauty, with thickly forested mountains, powerful waterfalls and the lush green rolling hills of the western side.

Fishing although there is nothing organized as of yet. Mondulkiri's rivers and streams would probably make for some good fishing. Bring your own lightweight gear and give it a try. Sen Monorom would be a great place for mountain biking. There are now no rentals there, so you would have to bring one along on the airplane.
