This is one of Thailand’s most amazing experiences, whether you are a nature lover or not. While it is only a 1 hour drive East of Khao Lak, it is very undeveloped and such an exciting place to visit. The park is very spectacular with dripping thick native verdant rainforest, punctuated by towering outcrops of limestone cliffs or karsts, waterfalls and sparkling streams, an island studded lake, several caves, and many trails, mostly along rivers. The heart of Khao Sok Natonal Park is the Chiaw Lan Dam (also known as the Ratchaprapha Dam) which was constructed across the Paseang river. This Chiaw Lan Lake occupies some 165 sq km and the vast area of water is actually retained by several small dams and the surrounding rock formations are overgrown with dense lush jungle.

Since then the area has gained more and more notoriety yet still retains it’s wild charms. The reservoir was completed in 1987 and the lake is now considered one of the most beautiful places in Thailand
