Set amid elevated pine forests, Kirirom National Park offers some small waterfalls and decent walking trails. Hook up with a ranger for a 2hr hike up to Phnom Dat Chivit (End of the World Mountain) where an abrupt cliff-face offers an unbroken view of the western mountain ranges.

It's one of the few national parks to have a community tourism programme and proceeds from its educational walks are pumped back into the community.
