Kaeng Krachan National Park

Kaeng Krachan National Park is Thailand's largest national park, covering 2,915 sq km across Phetchaburi and Prachuap Khiri Khan provinces, with its southern section in Hua Hin District. Established on 12 June 1981, it is part of the Kaeng Krachan Forest Complex UNESCO World Heritage Site inscribed in 2021. The park is notable for dense tropical forest, the Kaeng Krachan Reservoir, Pala-U Waterfall, and rich biodiversity including elephants, leopards and over 400 bird species.

Visitors can expect a large forested mountain park with reservoir, waterfalls and viewpoints. The Hua Hin access leads to dense evergreen forest, the 16-level Pala-U Waterfall, and the Panoen Thung mountain viewpoint (accessible by 4WD). Areas include visitor centres, campsites, bungalows, nature trails and boating areas on the reservoir. The environment is natural and remote, with opportunities for wildlife and birdwatching, photography and trekking through tropical forest.
