Phnom Nam Lear Sanctuary at a Glance#

Exploring Phnom Nam Lear Sanctuary#

Phnom Nam Lear Sanctuary is one of Mondulkiri’s finest areas for wildlife viewing, an almost idyllic setting with a diverse collection of flora and fauna. It is best known for a striking series of cliffs and waterways, along with several waterfalls to trek to and cool off in, and it is a particular favourite with birdwatchers for its mix of endemic and migratory species.

Treks are organised from Sen Monorom by four-wheel-drive vehicle. Visitors may camp in the reserve or stay in one of several small cottages for a little more comfort. The journey from Sen Monorom is a pleasure in itself, running for around four hours along winding country roads and through beautiful forest.
