Cheow Lan Lake is located in Khao Sok National Park in Surat Thani Province, southern Thailand. It boasts some of the country's most spectacular scenery. Although called a lake, it is actually a vast reservoir created in 1982 as part of the construction of the Ratchaprapha Dam to power a hydroelectric power plant. This flooded villages and mountains, resulting in a stunning artificial lake with limestone cliffs, verdant islands, and lush jungle, sometimes compared to Halong Bay in Vietnam – albeit on a smaller scale. Covering an area of ​​approximately 165 square kilometers, Cheow Lan Lake offers panoramic views of turquoise waters, mountains, karst formations, and jungle. A boat trip on the lake provides the opportunity to experience pristine nature and observe wildlife, including wild elephants that often emerge from the jungle in the late afternoon. What is there to see and do at Cheow Lan Lake? The three imposing limestone cliffs of the Three Brothers, rising from the water, have become a landmark of the lake and the entire Khao Sok National Park. This photogenic spot is often compared to the famous rock formations of Guilin in China. Boat Tours: The best way to explore the lake is by longtail boat (an absolute must to see the Three Brothers). These tours allow you to discover the hidden corners of the lake, observe the local wildlife up close, and admire the spectacular scenery. Boats depart from the Ratchaprapha Dam. You can explore the lake by boat for a few hours, a full day, or even two or more days, booking an overnight stay in a floating bungalow on the lake. An absolute must, but not without its price, as prices for floating hotels in Khao Sok have risen sharply in recent years. Jungle Trekking and Caving: Several tours combine boat trips with jungle trekking. Among the caves that are a must-see are Nam Talu Cave, famous for its stalactite formations and watercourses, and Coral Cave. 4. Wildlife viewing: Khao Sok National Park is home to exceptional biodiversity. Here you can observe gibbons, hornbills, and even wild elephants. A good guide who knows the best viewing spots is essential. Staying in a floating bungalow: An unforgettable experience on Cheow Lan Lake is staying in a floating bungalow. Accommodations range from simple bamboo bungalows with a fan (only for a few hours each night) to luxurious bamboo bungalows. Due to the exceptional location and high demand, prices are correspondingly high.

National Park entrance fee: 300 THB per adult and 150 THB per child (under 140 cm). Excursions: It is recommended to book excursions to Khao Sok in advance and purchase a package that includes transport, boat trip, meals, and, if desired, an overnight stay in a floating bungalow. Individual bookings are usually more expensive. However, for a simple boat trip on the lake, you can go directly to the Ratchaprapha Dam jetty and buy tickets at the ticket office there. In addition to the cost of the boat trip (captain only, no guide), the Khao Sok National Park entrance fee must be paid. Best time to visit: From November to April, during the dry season, to fully enjoy the scenery and activities. Least favorable time to visit: From September to mid-November, towards the end of the rainy season.

Cheow Lan Lake lies roughly halfway between the city of Surat Thani and the land entrance to Khao Sok National Park. The boat landing and Ratchaprapha Pier are about an hour's drive from Khao Sok village. You can reach the lake independently by car; otherwise, all hotels and travel agencies in Khao Sok offer package tours.
