Khao Sok is an incredible national park in southern Thailand full of limestone cliffs, caves, waterfalls, and some of the best-preserved jungle habitat in the country,  The forests here are so thick they're almost totally inaccessible, but a dam has created a huge reservoir right in the middle of the park. Traveling by boat on Cheow Lan Lake lets you get right up close to the jungle.

Most people book either a one-day tour two-day or a three-day  visit with an overnight. Stay at one of the floating bungalows on the lake. These trips usually include a jungle trek
