The park extends over the eastern part of the Cardamom Mountains. It is located 112 km from Phnom Penh off National Highway 4 on the road to Sihanoukville.
Lying at 675m (2,215 ft) above sea level, Kirirom was Cambodia's first officially designated national park[3].
It contains many footpaths through the forests with a number of small lakes and waterfalls and was once used as a refuge by the Khmer Rouge[4].
Among the animals in the park, the following deserve mention: Asian elephant, deer, Gaur, Banteng, leopard, Spotted Linsang, Pileated Gibbon and tiger.
Kirirom is now a popular recreation site. Within driving distance of Phnom Penh, on weekends a significant number of people travel to the park. Many vendors sell various types of food, though some visitors prefer to bring picnic lunches.
