Khao Sok
The world's oldest rainforest, older than the Amazon. Virtually unknown.
Khao Sok is Thailand's least visited major national park and home to the world's oldest rainforest. In 1987, a dam created Cheow Lan Lake: 165 km² of water dotted with 160 limestone islands and floating bungalows. Below is everything you need to know before heading into this part of Thailand.

Who it suits
- Nature lovers and hikers wanting something entirely different from the beach

- Travellers wanting to see Cheow Lan Lake: a night in floating bungalows among the cliffs
- Anyone on the Krabi, Phuket, Koh Samui route looking for a nature stopover
Less suited if…
- Beach-goers: Khao Sok has no beach; combine it with Krabi or Koh Lanta
- Those who value comfort over adventure: accommodation is simple and there are no luxury options
The sound of gibbons before sunrise is the best alarm clock on earth.

⚠️ Mistake to avoid

Questions
Frequently asked questions
When is the best time to visit Khao Sok?
November to April is the driest season, ideal for trekking and exploring the lake. But Khao Sok is also remarkable in the wet season (May, October): the rainforest is vivid green, there are fewer visitors and the lake rises, making the cliffs stand out even more dramatically. The rainy season is also when the Rafflesia flower blooms (the world's largest flower). Go whenever you can.
How do I get to Khao Sok?
Khao Sok sits on the route between Krabi/Phuket (2 hours) and Koh Samui (via Surat Thani, 2 hours). Minibuses depart daily from Krabi, Phuket, Surat Thani and Koh Samui. There is no train to Khao Sok itself; the nearest stations are Phun Phin (Surat Thani) and Chumphon. A car or minibus is the most practical option.
How many days do I need in Khao Sok?
A minimum of 2 nights, though more is better. Day 1: arrival and jungle trekking. Day 2: overnight on Cheow Lan Lake. Day 3: return and optional kayaking. With one night you'll miss the lake. With three nights you can fit in the night walk, cave route and gibbon spotting.
Is Khao Sok suitable for children?
Yes, if you plan well. Kayaking and a lake overnight are wonderful for children over 6 years old. Naam Talu Cave is only for children over 10 (physically demanding). Night walks are suitable for children over 8. Account for heat and insects: a good insect repellent is essential.
Can I combine Khao Sok with a beach?
Yes, and this is the most popular combination. Khao Sok sits perfectly between Krabi (2 hours) and Koh Samui (2 hours via Surat Thani). Fly into Krabi, head to Khao Sok (2 nights), then on to Koh Samui or Koh Lanta for a week at the beach. Or from Bangkok by train to Surat Thani, then bus to Khao Sok, then ferry to Koh Samui.

The world's oldest rainforest, a lake ringed by 160 limestone cliffs and gibbons that begin singing before sunrise. Still one of Thailand's most untouched natural areas.
