Although evidence of tiger presence has not been recorded recently, monitoring by Free-land Foundation in collaboration with Department of National Park rangers has discovered tigers (the Indochinese tiger subspecies) in other parts of eastern Thailand where they were previously thought to have been completely extirpated.[1] Its waterfalls include the 80 meter Heo Narok, and Heo Suwat made famous from the film The Beach. Namtok Sarika is popular with the Thais.
