Kirirom namely"Mountain of joy"by the King at the suggestion of a monk from Phnom Penh. A hill of 700m covers an area of 35,000 hectares. It is located 112 km from Phnom Penh off National Highway #4 on the road to Sihanoukville. The natural resort is decorated with many categories of pines imported from Japan. Park rangers charge foreigners a 20,000 riel (=$5) entrance fee.
The area is suitable for a day trip from Phnom Penh, but it is also possible to arrange accommodation. Near the main entrance is the rather expensive Kirirom Hillside Resort. A cheaper and friendlier option is the Chambok Ecotourism Site, a successful and sustainable community project.
Chambok Ecotourism site is just next to the Kirirom National Park. Be prepared for some exercise (4 km trek), interaction with local villagers, and discovery of Cambodia's unique natural biodiversity. It's good for hiking or bike rider to reach beautiful waterfall, Some peoples they bring there foods for eating at waterfall.
