Khao Sok National Park is a unique mix of very diverse ecosystems. Home to rainforest that’s older than the Amazon, the park also contains a limestone mountain range covered in karst formations, many kilometers of trails, and even a river you can explore on canoes or bamboo rafts. The park is home to Malayan sun bears, tigers, and wild elephants, and sightings aren’t rare once you get deep into the evergreen rainforest. The park is also famous for its eco-luxury camps, where tents come with en-suite bathrooms, deluxe bedding, their own kayak, and some of the best meals you’ll try in Thailand.
