Cheow Lan Lake · Khao Sok National Park · Thailand
Your trusted local guide for unforgettable experiences at one of Thailand's most spectacular natural wonders.
A Journey into Thailand's Emerald Wonderland
Arriving at Cheow Lan Lake in Khao Sok National Park is a moment that leaves a lasting impression. As the longtail boat glides across the calm emerald water, towering limestone cliffs rise dramatically from the lake, surrounded by one of the oldest rainforests on Earth. Every direction reveals spectacular scenery, making this one of the most breathtaking natural landscapes in southern Thailand.
Located in Surat Thani Province, Cheow Lan Lake covers around 165 square kilometres and was created after the construction of the Ratchaprapha Dam in the 1980s. Over the years, nature has transformed the reservoir into a remarkable destination where dense jungle, hidden coves, and impressive karst mountains create an unforgettable panorama.
The journey across the lake is an attraction in itself. Traditional longtail boats pass through narrow channels, quiet bays, and towering rock formations that reflect perfectly on the still water during calm mornings. Mist often drifts across the surface at sunrise, creating magical views that photographers and nature lovers will never forget.
Cheow Lan Lake is also home to floating raft houses where visitors can spend the night surrounded by untouched wilderness. Waking up to the sound of gibbons echoing through the forest and watching hornbills fly overhead is an experience unlike anywhere else in Thailand.
Wildlife thrives throughout the national park. Lucky visitors may spot macaques, dusky langurs, giant squirrels, monitor lizards, colourful kingfishers, and countless tropical birds, while the surrounding rainforest also shelters elephants, tapirs, and many other rare species, though these are much harder to see.
Popular activities include longtail boat tours, kayaking, canoeing, jungle trekking with experienced guides, cave exploration, wildlife safaris, and swimming in the warm freshwater lake — each offering a different perspective of this extraordinary landscape.
The first view of Cheow Lan Lake is more than a beautiful landscape — it is a reminder of Thailand's remarkable natural beauty. Towering cliffs, emerald water, ancient rainforest, and peaceful silence combine to create a destination that belongs on every traveller's bucket list. Whether visiting for a day or staying overnight on a floating bungalow, Cheow Lan Lake delivers unforgettable memories from the very first moment of arrival.
The best time to visit is during the dry season from November to April, when the skies are generally clearer and the lake is especially calm. Early morning departures offer the most peaceful atmosphere, cooler temperatures, and the best light for photography before the larger tour groups arrive.
Lightweight clothing, comfortable walking shoes, insect repellent, reef-safe sunscreen, drinking water, a waterproof bag for cameras and phones, and a light rain jacket — tropical showers can appear at any time of year. Please help preserve this environment by avoiding litter, staying on marked trails, and never disturbing wildlife.
