A day loop into Thailand's first national park (1962) and a UNESCO World Heritage Site. Khao Yai is one of Asia's most accessible rainforest parks — elephants, gibbons, hornbills, and pythons all live within an hour of Pak Chong town. The Thanarat Road climbs from lowland farms into evergreen forest, past the visitor centre at 760m, then descends to the Haew Suwat waterfall used as a location in Danny Boyle's 1999 film "The Beach". Best in cool season (November–February).
