Isolated, eerie, and beautiful, Cheow Lan Lake sits in the heart of Khao Sok National Park. Don’t take the risk of self-driving. Enjoy it with a guide in a group no larger than 10 on this all-inclusive door-to-door tour. Hike to a secret cave, ride a bamboo raft, enjoy a Thai lunch in a floating restaurant, and swim, kayak, and relax. Along the way, visit a local market.
