About Kaeng Krachan National Park

Kaeng Krachan National Park is Thailand’s largest national park, renowned for its lush evergreen forests, diverse wildlife, and scenic waterfalls, making it a top destination for nature lovers and outdoor adventurers.

Wilderness Landscape & Natural Heritage

Kaeng Krachan National Park, established in 1981, covers over 2,900 square kilometers on the border between Thailand and Myanmar. It features dense tropical rainforest, undulating hills, and a large reservoir created by the Kaeng Krachan Dam. This park is part of a vital conservation corridor in western Thailand, protecting some of the region’s most distinctive wildlife, including gibbons, Asian elephants, and elusive clouded leopards. Birdwatchers visit for rare species such as hornbills and pittas. The park showcases various natural attractions like Pa Wai Waterfall, which plunges into emerald green pools, and scenic viewpoints offering expansive vistas over forested mountains. Hiking is popular here, with trails winding through old-growth forest and offering chances to encounter wildlife and unique plant species. The park’s remote location and minimal light pollution also make it a favored spot for stargazing. Visitors can camp or stay overnight at ranger stations to experience the wilderness fully. Despite its ecological importance, portions of the park are closed periodically to protect sensitive habitats and hours must be observed when visiting the dam and reservoir areas. Kaeng Krachan is a vital refuge for biodiversity and a destination that combines serenity with rich opportunities for trekking, wildlife watching, and exploring pristine rainforest.
