Cheow Lan Lake – Thailand’s Hidden Jewel in Khao Sok

Nestled within the breathtaking Khao Sok National Park in southern Thailand, Cheow Lan Lake is one of the country’s most stunning and lesser-known destinations. Formed by the construction of the Ratchaprapha Dam in the 1980s, this emerald-green lake is dotted with towering limestone karsts, lush jungle, and floating bungalows that seem to drift between the clouds and water. Unlike Thailand’s bustling beaches or cities, Cheow Lan Lake offers a serene and almost surreal escape, where nature dominates every view. For those seeking adventure, tranquility, or a chance to immerse in untouched wilderness, this is a destination not to be missed.

What to See
Cheow Lan Lake is a feast for the eyes and soul. The iconic limestone cliffs rising vertically from the water are reminiscent of Halong Bay in Vietnam but with a uniquely Thai character. A boat trip across the lake is the best way to take in its vast beauty, with stops at hidden caves like Pra Kay Petch Cave or Coral Cave, known for their dramatic formations. Wildlife enthusiasts will love exploring the surrounding rainforest, home to elephants, gibbons, hornbills, and even wild cats. The highlight for many visitors is staying overnight in one of the floating raft houses, where you can wake up to the sound of the jungle and the mist rolling across the water. Kayaking, swimming, and stargazing are just a few of the activities that make a visit unforgettable.

Travel Tips
Access to the lake is through Ratchaprapha Pier, about 1.5 hours from Surat Thani. Private transfers and local buses are available.
Overnight stays in floating bungalows should be booked in advance, especially during high season (November–April). Options range from rustic bamboo huts to more comfortable eco-resorts.
Most tours include meals, guided activities, and boat transfers. Consider a 2–3 day stay to truly experience the area.

Final Thoughts
Cheow Lan Lake is one of Thailand’s true hidden gems, offering a different kind of beauty compared to its famous islands and beaches. With its waters or simply admiring the sunrise from your bungalow, Cheow Lan promises a once-in-a-lifetime experience.
