Chiew Larn Lake
Chiew Larn Lake, also known as Ratchaprapha Dam, is located in Khao Sok National Park, Surat Thani Province. It is a tourist destination filled with beauty and tranquility, with stunning limestone mountains lining the emerald green waters, creating a peaceful and serene atmosphere. It is ideal for relaxation and truly connecting with nature.
One of the most interesting and iconic landmarks of Chiew Larn Lake is the “Three Peaks” (Khao Sam Gliew), a group of three limestone peaks located in the middle of the lake. These limestone islands resemble peaks emerging from the water, standing tall amidst the lake, surrounded by stunning scenery. It is a perfect spot for photography and experiencing the wonders of nature.
Chiew Larn Lake
Chiew Larn Dam was officially opened on Wednesday, September 30, 1987, with King Bhumibol Adulyadej presiding over the ceremony to inaugurate the dam and the hydroelectric power plant. The dam was renamed “Ratchaprapha Dam,” meaning “The Light of the Kingdom,” as its primary purpose was to generate electricity.
