Why go
Khao Sok is one of the oldest rainforests in the world, with huge trees, hornbills and the giant Rafflesia flower.
Cheow Lan lake has floating bungalows among karsts.
Night safaris are memorable.
Jungle trails lead to waterfalls and caves.
Gibbons and hornbills are common at dawn.
Cheow Lan lake is the highlight for most visitors. Formed by the Ratchaprapha dam, it's a vast emerald lake surrounded by limestone cliffs rising straight from the water. Floating raft houses, simple bamboo bungalows on the water, let you wake up to mist drifting between the karsts and swim straight from your doorstep.
In the forest itself, guided walks lead to waterfalls, caves full of bats and, if you're very lucky in the right season, the giant Rafflesia flower, which can be nearly a metre across.
The story
The lake was created by a dam in the 1980s.
The forest is older than the Amazon.
The dam flooded valleys, creating the lake.
Locals tell legends of forest spirits.
The rainforest of Khao Sok is often described as older than the Amazon, having survived through ice ages in a stable climate. It is home to elephants, tigers (rarely seen), clouded leopards, tapirs and hundreds of bird species.
When the dam was built in the 1980s, valleys and villages were flooded, and wildlife rescue operations moved animals from the rising water. The story is still remembered locally.

Getting there
Drive north; tours include transport.
Tours include transfers.
