Kaeng Krachan National Park

Spanning an area of over 2,900 square kilometres, the Kaeng Krachan National Park is the largest national park in the entire country. You’ll find this park along the Burmese border in western Thailand, and it is adjoined with the Burmese Tanintharyi Nature Reserve on the other side.

This national park consists chiefly of tropical rainforest growing on the eastern slope of the Tenasserim Mountain Range. The biodiversity is high, and includes both tropical and subtropical species. Despite being a national park, prive plantations do exist here.

Many of the tourist that visit Kaeng Krachan National Park have their lodging in the nearby beach town Hua Hin, on the Gulf of Thailand. Phetchaburi City, also located on the gulf coast, is another option.
