Kaeng Krachan National Park
Park Thailand's largest national park, rich in biodiversity
Thailand’s largest national park, Kaeng Krachan spans rainforest, misty hills and reservoir shores; visitors come for overnight wildlife spotting, birdwatching, waterfalls and eco-lodges along dirt forest roads.
Kaeng Krachan National Park is Thailands largest protected area, covering extensive lowland and montane rainforest along the Myanmar border. The park protects large continuous forest tracts, watershed areas and a reservoir that supports diverse wildlife and birdlife.
Visitors go for rainforest hikes, birdwatching, reservoir views, and to see waterfalls and remote forest camps; wildlife recorded in the park includes large mammals and a rich assemblage of forest birds. Facilities are focused on a few ranger stations, campsites and designated viewpoints rather than extensive tourist infrastructure.
The park was designated to protect the watershed and remaining lowland forest and to provide contiguous habitat across provincial boundaries. It remains an important conservation area with restricted and managed access in interior zones.
Kaeng Krachan lies in western Thailand, straddling Phetchaburi and Prachuap Khiri Khan provinces along the border with Myanmar, southwest of Bangkok.
- Access note: Access is mainly by road from Phetchaburi or Prachuap Khiri Khan; sections of the park become difficult in heavy rain and some interior roads are unsealed.
What to See #
- Kaeng Krachan Reservoir: Kaeng Krachan Reservoir formed by a dam is a central water feature inside the park and a focus for wildlife and bird activity.
