This exhilarating hike is one of the best adventures that the Khao Sok national park has to offer! The trailhead is located in the western part of the Cheow Lan lake, near the Tone Toey raft house, and begins in a section of dense jungle. After about 45 minutes hikers arrive at the mouth of the cave. Here, everyone ventures underground: the exit is located far away, and the only route is through the cave.
Entering the cave, hikers will be underground for nearly an hour. Nam Talu cave has many beautiful chambers, but the gem is the river of cold, crystal clear water. Hikers will follow the river, often wading through it. In a couple of places they will need to climb up and down small waterfalls.
