A Khao Sok lake tour is a guided long-tail boat trip on Cheow Lan Lake, the reservoir behind Ratchaprapha Dam inside Khao Sok National Park. A one-day lake tour costs ฿1,550–2,895 per adult with lunch, runs roughly 08:30–17:30 from Khao Sok village, and visits karst pillars, a cave and a floating raft house. Overnight versions start around ฿2,500. Most listings exclude the ฿300 lake fee and ฿40 pier fee.
It's the single best thing to do in Khao Sok, and it's easy to get slightly wrong: wrong season, wrong raft, fees you didn't expect. Here's how to get it right.

Introduction to Khao Sok Lake Tours
What is a Khao Sok Lake Tour?
A Khao Sok lake tour is a day or overnight trip onto Cheow Lan Lake with a boat driver and usually a guide. The reservoir drowned a valley of limestone peaks, so today more than 100 islands and pillars stand out of emerald water, surrounded by rainforest that runs to the horizon. People compare it to Guilin, Ha Long Bay and Phi Phi. Unlike those, it's fresh water and nearly silent.
What makes it different from other boat trips in Thailand: you sleep on it if you want to. Raft houses (floating bungalows) are moored in the lake's arms, and the boat safaris at dusk and dawn are when gibbons call and elephants sometimes come down to the shore. It's natural beauty with a bit of adventure: caves you wade through, trails with leeches in the wet season, and no phone signal on many arms of the lake.
Types of Tours Available
The different lake packages on sale:
- One-day lake tour (group): boat, a cave or short jungle walk, lunch on a raft, swimming and kayaking. The standard Khao Sok boat tour.
- Private long-tail tour: your own boat for 4 hours or a full day; GetYourGuide lists private 4-hour boats from about €140–147 per group.
- 2 days / 1 night: the day tour plus a raft-house night, evening and dawn safaris and a second cave or trek.
- 3 days / 2 nights: more of the same at a slower pace; about ฿400–500 extra.
- Floating resort stays: air-conditioned bungalows at places like 500 Rai or Keeree Tara, sold as packages.
- Jungle-and-lake combos: a night in the village or a jungle camp plus a night on the lake (Elephant Hills, Our Jungle House).
The unique feature of Cheow Lan Lake tours is the combination of jungle trekking and floating bungalows in one trip. See the floating bungalows tour for the overnight in detail.

The national park fee explained: Cheow Lan Lake has its own ticket, ฿300 per adult and ฿150 per child (3–14), paid separately from the ฿200 headquarters ticket, plus a ฿40 pier cleaning fee. Thai citizens pay ฿40/฿20. If you sleep on the lake, the ticket covers both days. Full details on the entrance fee page.
Tips for budgeting: carry ฿500–1,000 cash per person for fees, drinks and a tip for the boat driver; the rafts sell beer and snacks, but there are no ATMs on the water. Buying snacks at Ban Ta Khun market on the way is cheaper.
Accommodation Options
Floating bungalows on Cheow Lan range from bamboo huts with a mattress and fan to air-conditioned villas with private decks. Other accommodation types:
- Park-run raft houses such as Nang Prai (central, "Little Guilin" views) and Khlong Kha (the lake's south end): basic, scenic, often booked long ahead for the modern rooms.
- Private raft houses such as Praiwan, Saichon or Smiley Lake House: tour-package standard.
- Floating resorts: Panvaree The Greenery, 360 Issara, Keeree Tara, 500 Rai.
- Village hotels in Khao Sok: sleep on land and do the lake as a day trip.
| Option | Pros | Cons |
|---|---|---|
| Basic raft house | Cheapest night on the water, the full lake experience | Shared bathroom, power only in the evening, thin walls |
| Floating resort | Air-con, private bathroom, better food | ฿7,999+ packages, sometimes far from the pier |
| Village hotel + day trip | Comfort, restaurants, flexibility | You miss dusk and dawn on the lake |
Activities and Experiences
Exciting Activities Included
Jungle trekking on a lake tour is usually a 30–90 minute walk from a landing to a cave: Diamond Cave (Pra Kay Petch), Coral Cave in Klong Saeng Wildlife Sanctuary (extra ฿200 ticket), or Nam Talu, a river cave where you wade and sometimes swim (closed 1 June–30 November). Some groups see fruit bats hanging in the caves.
Longtail boat rides are the backbone: 45–80 minutes out to the rafts, then short hops between pillars, coves and landing points. Sit forward for photos, back for less spray.
Wildlife safari opportunities come on overnight tours: a late-afternoon boat ride and another around 07:00, when the lake is calm and gibbons call. Hornbills are regular; wild elephants on the shoreline are a lucky bonus, most often in the dry season. Swimming and kayaking fill the gaps.
Tour Duration and Itinerary
Typical durations: 7–9 hours for a day tour from Khao Sok village, 11–13 hours from Krabi or Phuket, and 24–30 hours for an overnight. Sample itineraries:
One-day lake tour from Khao Sok
- 08:30 pickup in Khao Sok village, drive east on Highway 401
- Short stop at Ban Ta Khun market
- About 10:00 at Cheow Lan Pier; pay fees; board the long-tail
- Boat past the three limestone pillars to a cave landing; short hike
- Lunch on a raft house; swim or kayak
- Return to the pier mid-afternoon; back in the village about 17:30
2 days overnight Khao Sok lake tour (Smiley's published schedule): meet 08:20, minivan 09:30, 7-Eleven stop 10:30, boat 11:30, lunch at the lake house 12:30, Guilin rock and Diamond Cave plus sunset boat at 16:00, dinner 18:45; next morning boat safari, trek to Bang Hoi waterfall at 09:00, lunch 12:00, boat back 13:30, village 16:00.
Highlights of Cheow Lan Lake visits: the three pillars, the first sight of the rafts, the dawn mist. You'll get all three on an overnight. A day trip gives you the first two.
Logistics and Travel Information
Transportation and Logistics
How to reach Khao Sok Lake from Surat Thani: Surat Thani airport is about 1 hour's drive from Cheow Lan Pier; a taxi costs about ฿1,600. Minivans from Surat Thani drop at Ban Ta Khun, about 13 km from the pier, where songthaews (shared pickups) run roughly hourly or leave at once for ฿600. If your tour starts at the pier the same day, take a taxi; public vans often arrive too late.
Logistics of using long-tail boats: boats are arranged through tour operators or raft houses, not hailed at the pier. In high season they run short, so arrange the boat when you book, not on arrival. Boats don't operate before sunrise or after sunset, and the furthest rafts are up to 1 hour 20 minutes out.
Travel tips for a smooth journey:
- Leave big bags in the village; take a daypack and a dry bag.
- Bring cash; the shop stop on the way (Ban Ta Khun market or a 7-Eleven) is your last chance for an ATM.
- Expect little or no phone signal; only AIS covers parts of the lake.
- Pack a head torch, sandals that grip, and a long-sleeved layer for dawn.
Guided Tours and Expertise
Guides turn a boat ride into a lake tour. They know which coves elephants use, where gibbon families sleep, when a cave is safe after rain, and how to read a storm coming over the ridge. On raft houses, guides also run the evening and morning safaris.
The expertise varies. Premium operators (Elephant Hills, Khaosok.com tours) use TAT-licensed English-speaking guides; budget group tours sometimes send a boat driver who speaks little English. Benefits of choosing a guided tour: safety in caves, far better wildlife spotting, and someone to handle fees and bookings. For private wildlife-focused guiding, look at the Wildlife Explorer tour.
Booking and Timing
Booking Your Khao Sok Lake Tour
Steps to book a tour:
- Decide day trip or overnight, and which raft standard.
- Pick a departure: Khao Sok village, Khao Lak, Phuket, Krabi or Surat Thani.
- Message two or three operators with dates and group size; compare inclusions, not just price.
- Confirm the raft name, what's included (fees? transfers?) and the cancellation policy in writing.
- Pay the deposit; bring the balance and the fees in cash.
Recommended booking platforms: direct with local operators such as Khao Sok Center Tour, Smiley or Our Jungle House; your guesthouse desk; or GetYourGuide for card payment and reviews. Tips for securing the best deals: book direct in the village in the low season, share a private boat with other travellers, and avoid street agents in high season (there are stories of overbooking at the pier).
Best Time to Visit Khao Sok Lake
Ideal seasons: December to April for dry weather and clear mornings; January to March is the driest stretch. The rainy season runs from late April to early December, with most rain between May and October, usually as heavy afternoon bursts rather than all-day drizzle. Temperatures sit between about 22°C and 36°C all year.
Weather considerations: lake levels and boat availability change with the season. Nam Talu Cave closes 1 June–30 November. May to early July and September to early November have the easiest boat availability. Events and festivals to consider: there's no lake festival as such, but Thai holidays such as New Year and Songkran (mid-April) fill rafts with domestic travellers, so book those dates early.
FAQ
How much does a Khao Sok lake one-day tour cost?
A Khao Sok lake one-day tour costs ฿1,550–1,800 per adult from Khao Sok village; a Krabi operator lists ฿2,895 with Diamond Cave included. From Krabi or Phuket, private per-head prices run ฿2,099–5,799 depending on group size. Add ฿340 in lake and pier fees unless they're included.
Can you visit Khao Sok without a tour?
Yes, you can visit Khao Sok without a tour. The headquarters trails, the Sok River and the village are easy on your own. The lake is harder: you can reach Cheow Lan Pier by taxi or minivan and songthaew, but boats and raft houses are best arranged in advance through an operator or raft house.
Are there tigers in Khao Sok?
No tigers have been seen in Khao Sok for decades. A few may survive in remote forest, but they don't appear even on camera traps, and no lake tour will show you one. Gibbons, hornbills and, occasionally, wild elephants are the realistic highlights.
What are the best tours to Khao Sok National Park?
The best tours to Khao Sok National Park are an overnight Cheow Lan Lake tour with a raft-house night, a private long-tail day on the lake, and, for wildlife, a small-group or private guided trip. From Khao Lak, the land tours with trekking and bamboo rafting are the easiest day out.
