Khao Sok National Park is the oldest evergreen forest in the world, with some estimates putting it at well over 150 million years old. The park is also home to a huge array of wildlife including tigers, elephants, leopards and a wide range of monkeys, snakes and birds. While Khao Sok park presents the usual jungle trekking fun, the reason we headed to the park was for its stunning artificial lake right in the heart of the park – Cheow Lan Lake. If you’ve seen photos of floating bamboo bungalows then they’re most likely right here.
