Thailand Khao Sok

The South’s most popular nature reserve, Khao Sok National Park is home to 738-sq-km of virgin lowland jungle, towering limestone karsts, waterfalls, caves and the dazzling man-made Cheow Lan Lake. Also known as Ratchaprapha, the lake was formed in the 1980s by one dam and countless vertical limestone castles sculpted by nature's hand. Due to its size, the park houses a number of rare species, including tigers, gibbons, hornbill birds, a variety of orchids and the giant parasitic Rafflesia flower. The park is also known as a top destination for watersports, caving and trekking.

Experience

Khao Sok is one of Thailand's best-known national parks, and makes a convenient stop-off for family itineraries calling at Thailand's southern beach destinations. The park’s centrepiece is a reservoir, Ratchaphrapa or Chiew Lan, one of the most magnificent bodies of fresh water in Southeast Asia. The emerald water glistens between 1,000-metre high limestone mountains. You can take a boat tour lasting a few hours or a full day, or you can spend a night at one of 17 raft-house lodgings. They all come with kayaks. West of the reservoir are caves and waterfalls, and a trail guide is required to access most of them. This area is also where you'll find the rafflesia kerrii, the fire-red, so-called dinosaur flower that smells rank and is one of the world's largest flowers when it blooms in the dry season. Though large mammals are rare, Khao Sok is full of birds and reptiles. Most people will visit as part of an organised tour that includes accommodation, transfers in/out of the park, and guided nature hikes.
