On this exciting excursion, a longtail boat drops you and your guide at the northern tip of Klong Long where the Coral Cave trail begins. After a scenic and simple 45-minute hike through the forest you’ll arrive at a private inner lake known as 500 Rai. From here, a Khao Sok National Park ranger will ferry you (via bamboo raft) to the spectacular 10,000 year-old Coral Cave. Once inside, you’ll wonder at authentic ancient rock formations and immerse yourself in the cavernous interior while your informative guide explains the local geology, pointing out favorite formations. Exploring the Coral Cave is a great family activity and a favorite for children of all ages!
