Pang Sida National Park
Nestled in a remote, mountainous region near the Cambodia border in eastern Thailand’s Sa Kaeo province, Pang Sida national park is less accessible than Khao Yai immediately to the west, but is equally stunning. Pang Sida is also far less touristy; show up on a weekday and there’s a good chance you’ll be sharing the park’s 844 square kilometres only with its wild elephants and many other species of wildlife. If arriving between May and September, you’ll also get to frolic with the thousands of butterflies that emerge from the forest during wet season.
