The rolling hills of the Kirirom National Park are zigzagged with well-trodden trails and dotted with waterfalls, lakes and abundant wild plants. An important wildlife sanctuary, the park's slopes are home, despite illegal logging, to forests of Pinus merkusii, a pine tree not found anywhere else in Cambodia. Although poaching has taken its toll, species of deer, wild ox (gaur and banteng), elephant and leopard still inhabit the depths of the park.
