Preah Soramrith Kosamak Kirirom National Park is on Kirirom Mountain, in Damrei Phong village, Kirirom commune, Phnom Sruoch districts, about 117 kilometers southwest of Phnom Penh. The mountain is 700 meters high. A natural site, it once was Preah Kosamak town. This well-conserved park, abundant in fresh air, has waterfalls and is full of tall pine trees and orchid flowers.

There are not many types of larger wildlife in evidence on Kirirom, but it is an ideal spot to glimpse some of the country’s unique birdlife and birdwatchers even come from overseas to visit. The national park is more interesting during or just after the rainy season; not that many fires on the ground and waterfalls having well water.
