Virachay National Park

National Park Mountainous national park with dry forest habitats

Overview - Virachey National Park is a large protected area in northeastern Cambodia established in 1993 to conserve extensive tracts of evergreen forest and mountainous terrain. It covers several thousand square kilometres across remote parts of Ratanakiri and neighboring provinces.

What visitors find - The park offers long-distance trekking, riverine travel, and wildlife observation in a sparsely populated landscape; trails and access are limited and journeys are typically multi-day and guide-dependent. The area’s remoteness is a draw for experienced eco-travelers seeking intact forest and river systems.

History - Created to protect intact forest and biodiversity in the Annamite Range, the park has seen conservation programs and community-based initiatives alongside ongoing challenges from illegal logging and hunting. Management has included zoning and cooperation with local ethnic communities.

Location - The park lies in Cambodia’s far northeast, encompassing parts of the Annamite Range and plateaus in Ratanakiri and adjacent provinces, with Banlung as the nearest major town and administrative hub.

  • Establishment and scale: Designated in 1993 and covering several thousand square kilometres, the park spans remote northeastern Cambodia and includes rugged terrain and limited road access.
  • Wildlife highlights: Contains habitat for species such as Asian elephant and various gibbon species, with conservation and anti-poaching efforts ongoing due to its remoteness.

What to See #

  • Annamite highlands: An area of the Annamite Range and adjacent plateaus characterized by evergreen and semi-evergreen forest that form the park's core habitats for large mammals and primates.

How to Get to Virachay National Park #

Virachey National Park (northeast Cambodia) is very remote. The usual access is from the provincial towns of Banlung (Ratanakiri) or Stung Treng - you should arrange a 4x4 transfer or an organized tour from those towns as access into the park is via long unpaved forest roads and tracks; expect several hours of driving from the nearest towns and no regular public bus service into the park.

Tips for Visiting Virachay National Park #

  • Visit in the dry season (roughly November-April) and aim for early morning starts - trails and lowland forest are far more passable and wildlife is more active before midday heat.
  • Access is remote and infrastructure is limited; arrange permits and a ranger-guided multi‑day trek through a reputable operator based in Banlung or Stung Treng rather than attempting independent overland routes.
  • Many visitors only do short roadside stops - to see the park's best habitat and waterfalls plan a longer itinerary (overnight camping or village stays) so you can reach quieter interior sections that most day-tripters miss.
