Khlong Phanom National Park, Surat Thani
Khlong Phanom National Park is a lush rainforest nestled along the limestone mountain range in western Surat Thani province. Lying between Khao Sok National Park and Cheow Lan Lake, the landscape is dominated by steep limestone peaks, deep valleys, evergreen forest, clear streams and tranquil waterfalls. It is an ideal destination for travellers who love truly wild nature and prefer quieter, less crowded places.
Park Overview
History of the National Park
Originally, the Khlong Phanom area formed part of a continuous block of rainforest in southern Thailand, characterised by rugged limestone mountains and numerous small streams. For many years, the region was used for logging and agriculture. However, surveys revealed its importance as a major headwater area for the Tapi River basin and a refuge for rare wildlife, prompting government agencies to seek stronger protection.
Following extensive assessments of forest resources, wildlife and watersheds, the area was designated as “Khlong Phanom National Park” in 2000. The park was created to conserve its evergreen forest, unique limestone ecosystem and to prevent further encroachment and degradation of this valuable landscape.
Size and Conservation Significance
Khlong Phanom National Park covers roughly 400–410 square kilometres. More than 80% of the area consists of steep limestone mountains and hills, blanketed by dense evergreen forest. This forest acts as a natural “sponge”, absorbing and slowly releasing water throughout the year.
The park is the headwater source for several important streams, including Khlong Sok, Khlong Saeng and Khlong Phanom, which collectively feed into the Tapi River. These waters are vital for agriculture, domestic use and freshwater ecosystems in Surat Thani province.
The intact forest also supports a range of rare and endangered species, such as wild elephants, Malayan tapir, serow and several hornbill species, underlining the park’s conservation value.
Role of the Park for Local Communities & the Tapi River Basin
Beyond its ecological functions, Khlong Phanom plays a crucial role for surrounding communities. The park’s headwater forests help regulate stream flow, reducing flood and landslide risks during the rainy season and ensuring reliable water supplies for agriculture and daily use during drier months.
From a socio-economic perspective, the park supports local livelihoods through eco-tourism. Community members can earn income as trekking guides, boat operators, homestay hosts, restaurant owners and providers of various tourism services. When managed responsibly, this income helps to strengthen local economies and encourages communities to actively participate in forest protection.
