Than Bok Khorani National Park

Than Bok Khorani National Park is a protected national park in Ao Luek District, Krabi Province, southern Thailand. Established in 1998, it covers about 104 sq km of limestone karst mountains, mangrove forests, waterfalls, caves and coastal islands in the Andaman Sea. It is notable for its emerald pools, the Than Bok Khorani waterfall, sea caves with prehistoric paintings, and islands such as Koh Hong.

Visitors can expect a diverse natural landscape of limestone cliffs, dense mangrove forests, freshwater streams and coastal islands. The park centre features a short nature trail through shaded forest to the Than Bok Khorani waterfall and emerald pools. Visitors can explore caves such as Tham Lot and Tham Phi Hua To by foot or kayak, paddle through mangrove channels, view stalactites and stalagmites, and take boat trips to offshore islands with beaches and lagoons.

Established on 30 September 1998 as Thailand's 88th national park, covering 104 sq km across Ao Luek, Mueang Krabi and Khlong Thom districts. The park is archaeologically significant for Tham Phi Hua To and other caves containing prehistoric rock paintings, shell middens and human remains estimated to be around 2,000-3,000 years old.

Tham Phi Hua To Cave is culturally significant for its ancient rock paintings depicting human figures and animals, reflecting early human habitation in southern Thailand. The caves and limestone landscape hold local cultural value and are interpreted for visitors through guided tours and visitor centre displays.
