An ancient rainforest split by a deep turquoise lake.
introduction
Overview
Khao Sok sits in southern Thailand, divided into two distinct zones separated by an hour's drive. Khlong Sok Village hosts national park headquarters and main forest walking trails. Cheow Lan Lake offers floating raft houses anchored beneath limestone karst peaks. You move between them by local minivan or songthaew, balancing deep jungle hikes with water transport.
Pier versus village choice
Surat Thani buses drop off on Route 401, a short walk from park headquarters. Cheow Lan Pier sits 65 km further east.
Ancient ecosystem
Khao Sok contains one of the world's oldest evergreen rainforests, predating the Amazon basin.
Park fee double-pay guard
Your 300 THB park entry ticket lasts 24 hours. Plan lake and jungle entries within one calendar window to avoid paying twice.

Southern spices and jungle bamboo cooking
Food in Khao Sok relies on southern Thai staples, where wild turmeric, stink beans, and intense curries dominate. Local guides prepare traditional jungle meals inside hollow bamboo stalks over open campfires during overnight treks. Village eateries cater to international palates alongside fiery regional options.

history
A short history
Khao Sok's dense canopy served as a secure base for Thai Communist insurgents between 1975 and 1982. Their presence kept commercial logging and mining firms out of the region, unintentionally protecting the primary rainforest. In 1980, the Thai government established the area as Thailand's 22nd national park, followed by the 1982 flooding of the central valley to build Ratchaprapha Dam.
