Thap Lan National Park

Thap Lan National Park is Thailand's second-largest national park, covering 2,236 sq km across Nakhon Ratchasima, Prachinburi, Buriram and Sa Kaeo provinces, with its northern section in Wang Nam Khiao District. Established in 1981, it is notable for containing the world's largest remaining stand of Lan or fan palm trees (Corypha lecomtei) and for forming part of the Dong Phayayen-Khao Yai Forest Complex UNESCO World Heritage Site. The park comprises mixed deciduous and evergreen forests, grasslands, waterfalls and diverse wildlife.

Visitors can expect a large forested national park with dense Lan palm groves, mixed deciduous and dry evergreen forest, open grasslands and low hills. Areas accessible to visitors include marked nature trails, viewpoints, waterfalls such as Lam Mun Bon and Huai Yai, camping grounds and the visitor centre area. The environment is natural and relatively undeveloped, with opportunities for nature walks, wildlife observation, birdwatching and photography. Facilities are basic and focused on nature-based tourism.
