What to See in Virachey National Park

Scale and Remoteness

Virachey is Cambodia’s largest protected area, stretching from dense evergreen forest to open grassland plateaus and mountains along the Laos and Vietnam borders. Visitor numbers are tiny by Southeast Asian standards — multi-day treks here can go entire days without encountering another travel group.

Multi-Day Trekking Routes

Routes range from roughly 3-day introductory treks to demanding 7–10 day expeditions deep into the park’s interior, camping overnight along the way. A certified local guide is mandatory for all routes — this isn’t a park set up for independent hiking.

Indigenous Communities and Wildlife

The park’s fringes are home to indigenous highland communities, and the forest interior shelters gibbons and other wildlife rarely encountered elsewhere in Cambodia, though sightings on any single trek are far from guaranteed given the dense forest cover.

How to Get to Virachey National Park

All treks are organized from Banlung, Ratanakiri’s provincial capital.

To Banlung: Around 585km/9–10 hours by road from Phnom Penh, or a shorter drive/flight connection via Siem Reap
Booking treks: Arrange through the park headquarters in Banlung or a licensed trekking operator well in advance — permits, guides, and porters all need pre-arrangement

Best Time to Visit

Stick to the dry season (November–March). Wet-season trails become difficult and leech-heavy, and some routes are closed entirely during the heaviest rains.
