Main image

Kirirom National Park is a protected forested area in Koh Kong province, Cambodia, known for its pine-covered plateau and higher-elevation landscape. The park is notable for its montane pine stands that contrast with Cambodia’s lowland tropical forests.

The site offers walking trails through pine forest, several small streams and waterfalls, and picnic or camping areas used by day-trippers and local visitors. Terrain is generally upland plateau rather than steep mountains, making it suitable for short hikes and nature walks.

The area was set aside for conservation and recreation during the 20th century and has been used locally for tourism and outdoor recreation since then. Management and facilities have developed incrementally to support visitors rather than as an original large-scale project.

The park sits on an upland plateau in southern Cambodia within Koh Kong province. It occupies higher ground compared with surrounding lowlands and is accessed by road from regional towns.

  • Climate tip: Higher elevations produce a noticeably cooler climate than the lowland plains; mornings and evenings can be cool year-round.

Tips for Visiting Kirirom National Park #

  • Visit Kirirom National Park in the dry season (roughly November-April) when trails, viewpoints and waterfalls are more accessible and the park's pine forest is at its most pleasant.
  • Enter via the main park gate off National Road 4 (the Phnom Penh-Sihanoukville corridor) and allow time to hire a local guide or ranger at the gate - guides help you find the park's best short treks and waterfalls that are easy to miss.
  • Use Phnom Penh as your base for logistics and transport; day trips are possible but staying one night inside or near the park lets you enjoy cooler evenings and sunrise views without a long return drive.
