Virachey National Park covers an area of 3,325 square kilometers overlapping the districts of Veun Sai and Taveng about 60 km north of Banlung town. The Virachey Park serves as the largest national park in Cambodia. Many of the trees here are about a thousand years or older; more than a hundred bird species including the Great Hornbill and Red-collared Woodpecker share the park with a diversity of other wildlife species.

The vast forests, grasslands, mountains, and valleys remain largely unexplored and undisturbed by human settlement and may still harbor new and undiscovered wildlife species.
Tigers, elephants, wild cattle, and several spectacular, globally threatened primate and bird species have been spotted here. The northeast of Cambodia has been the home to many indigenous hill tribes people for centuries and remains a center for cultural diversity in the region.
