Ratchaprapha Dam – The Jewel of Khao Sok

Ratchaprapha Dam (เขื่อนรัชชประภา), also known as Cheow Lan Dam, is a breathtaking hydroelectric dam located in Surat Thani Province. Built in 1982 across the Khlong Saeng River, it forms the spectacular Cheow Lan Lake, famous for its towering limestone karsts, emerald-green waters, and floating raft houses.

Often compared to Guilin in China or Halong Bay in Vietnam, Ratchaprapha Dam is a top destination for nature lovers, adventurers, and those seeking tranquility within Khao Sok National Park.

Key Features of Ratchaprapha Dam

1. Spectacular Scenery – Limestone Cliffs & Turquoise Waters

The Cheow Lan Lake, created by the dam, is the main attraction. Covering 165 square kilometers, it features hundreds of limestone karsts rising dramatically from the water, resembling a lost world of misty peaks and untouched wilderness.

    • Dam Viewpoint – A panoramic view of the lake and lush forest.
    • Three Brothers (Sam Khao Karst Formation) – The most iconic limestone cliffs.

    • Pra Kay Petch Cave (Diamond Cave) – A stunning cave with sparkling rock formations.
