Khao Sok National Park covers 739 sq km of Surat Thani province in southern Thailand. The park contains one of the oldest rainforests on earth — approximately 160 million years old, pre-dating the Amazon — and is home to gibbons, hornbills, langurs, wild elephants, and (rarely seen) tigers and sun bears. The centrepiece is Cheow Lan Lake, a 165 sq km reservoir created when the Rajjaprabha Dam was built in 1982. The lake is surrounded by near-vertical limestone karst towers rising 900 m from the water, creating a landscape that looks like something between Halong Bay and Jurassic Park.
The park sits roughly 100 km east of Khao Lak and 230 km north of Phuket, making it accessible as a day trip from either — though a day trip gives you perhaps 3–4 hours on the lake itself. The full experience requires at least one overnight, sleeping in a floating bungalow on Cheow Lan Lake with the karst walls rising around you in the dark, gibbons calling at dawn, and a boat safari in the morning before most visitors arrive.
Tours to Khao Sok are sold from multiple departure points — Phuket, Khao Lak, Krabi, and from the park village of Khlong Sok itself. The offerings range from efficient day trips to 2-day lake immersions with all meals included. Below are the best-rated tours currently available, with pricing in approximate ranges.

Best Day Trips from Phuket
1. Phuket: Khao Sok and Cheow Lan Lake Tour with Lunch
The most popular day trip from Phuket to Khao Sok. The tour departs Phuket early and makes the 2.5-hour drive to the lake, where you board a traditional longtail boat for a guided water safari through the limestone karst scenery. Hornbills, long-tailed macaques, and monitor lizards are regularly spotted. There is time for swimming in the lake and visiting one of the cave formations accessible by boat.
Lunch is included at a floating restaurant on the lake. The tour returns to Phuket in the late afternoon. Given the transit time, the actual time on the lake is approximately 3–4 hours — enough to understand why the place is worth more time, which usually motivates visitors to book an overnight stay on a return trip.
Duration: full day | Departs: Phuket | Includes: transport, longtail boat, lunch, swimming | National park fee: approximately ฿300 (may not be included — confirm on booking)
2. Phuket: Cheow Lan Lake, Diamond Cave, Hiking, All Included
A fuller-itinerary day trip from Phuket that adds Diamond Cave (a cathedral-scale limestone cavern with stalactite formations) and a jungle hiking segment to the standard lake boat tour. The “all included” description covers lunch at a floating restaurant, the cave visit, and hiking through a section of primary rainforest.
This is the better choice if you want to see more than the lake alone. Diamond Cave requires a 20-minute guided walk through the cavern interior and is one of the more impressive cave systems accessible from the park without specialist equipment. The hiking segment gives a sense of the jungle floor — fig trees, rattan, and the deep shade of a genuinely ancient forest.
Duration: full day (approx. 10–11 hours including transit) | Includes: transport, longtail boat, Diamond Cave, hiking, lunch | Departs: Phuket
3. From Phuket: Private Khao Sok Lake & Rafting
A private day trip from Phuket for couples, families, or small groups who prefer not to share a minivan and boat with strangers. The itinerary covers the lake boat safari, bamboo rafting (navigating the river sections upstream from the lake on a traditional bamboo raft), and the standard cave and swimming stops.
Private transport means early or late departure times can often be arranged, and the guide can adjust the on-water itinerary based on what you want to see. Good for wildlife enthusiasts who want to spend longer in productive zones rather than following a fixed group schedule.
Duration: full day | Format: private | Departs: Phuket | Includes: longtail boat, bamboo rafting, cave
Best Tours from Khao Lak
4. From Khao Lak: Khao Sok & Cheow Lan Lake Tour with Kayaking
Khao Lak is 50 km closer to Khao Sok than Phuket, which translates to roughly an hour less transit each way. This 8-hour tour covers the lake by longtail boat with wildlife spotting, a kayaking segment through the limestone karst channels, swimming in the lake, and lunch at a floating restaurant. The kayaking section is the distinguishing feature — paddling at water level between the karst walls is a qualitatively different experience from viewing them from a longtail.
A good option for Khao Lak resort guests who want a structured active day off the beach without a long drive.
Duration: 8 hours | Departs: Khao Lak | Includes: longtail boat, kayak, lunch, swimming
5. From Khao Lak: 2-Day Cheow Lan Lake & Bamboo Raft Tour
The strongest overnight option for Khao Lak-based travellers. Day one covers the drive to the park, a boat safari through the lake, swimming, a cave visit, and settling into your floating bamboo raft accommodation for the night. All meals are included from lunch on day one through breakfast on day two.
Day two begins with an early morning wildlife boat safari — gibbons are most vocal and visible at sunrise and hornbills cross the lake in the morning light. After breakfast, the tour returns to Khao Lak.
The overnight experience is the point at which Khao Sok moves from impressive to transformative. The sounds of the jungle at night, the near-total darkness, and the lake surface at dawn are experiences that a day trip cannot replicate. If you are in the region for more than a week, this is worth rearranging your schedule around.
Duration: 2 days / 1 night | Departs: Khao Lak | Includes: accommodation on floating bungalow, all meals, longtail boat, cave, wildlife safaris
Best Tours Based in Khao Sok (Khlong Sok)
6. Khao Sok: All-Inclusive Cheow Lan Lake, Diamond Cave, Hike, Kayak
Designed for travellers who are already staying in Khlong Sok village (the main base for independent visitors to the park), this full-day tour covers all the major lake attractions: the boat safari, Diamond Cave, a jungle hike, kayaking through the karst channels, and lunch. The “all-inclusive” framing covers food, activities, and park fees.
This is the best single-day option if you are basing yourself in Khlong Sok for a few nights and want one structured tour day alongside independent jungle walks and evening wildlife spotting.
Duration: full day | Departs: Khlong Sok | Includes: boat, cave, hike, kayak, lunch, park fees
7. Khao Sok Lake: Bamboo Raft House Overnight Stay
The classic floating bungalow overnight — simple bamboo accommodation on the lake, built in the style that Thai fishermen have used for generations. Bungalows have mattresses, pillows, and fresh sheets; shared bathrooms are on the raft structure. Electricity runs for a few hours each evening (approximately 18:00–22:00).
This is the budget-friendly overnight option. The accommodation is basic and the group format means you share meals and boat time with other travellers. But the location is identical to more expensive options — you are on Cheow Lan Lake, surrounded by karst peaks, in Khao Sok National Park — and the experience of the lake at night and at dawn is unchanged by the simplicity of the bungalow.
Duration: 2 days / 1 night | Departs: Khlong Sok | Format: group | Includes: bungalow accommodation, meals, boat safari
Best Tour from Krabi
8. From Krabi: 2-Day Khao Sok Jungle Safari with Overnight Stay
For travellers based in Krabi (approximately 3 hours from Khao Sok by road), this 2-day tour handles the transit, accommodation on the lake, guided boat and jungle activities, and all meals. The itinerary is similar to the Khao Lak 2-day option in structure but designed specifically around the longer Krabi departure point.
Krabi guests wanting to include Khao Sok in a southern Thailand itinerary without the logistics of independent travel will find this the most straightforward option.
Duration: 2 days / 1 night | Departs: Krabi | Includes: accommodation, meals, boat safari, jungle activities
How to Choose the Right Tour
Based in Phuket, one day available: Tour 1 or 2 — they cover the essential lake experience with manageable transit.
Based in Khao Lak: Tour 4 (day trip with kayaking) or Tour 5 (2-day overnight) — shorter drive, more time on the water.
Staying in Khlong Sok already: Tour 6 (all-inclusive day) or Tour 7 (overnight bungalow) — you are already at the park, take advantage of it.
Based in Krabi with 2 days spare: Tour 8 handles everything from a Krabi departure point.
Wildlife as the priority: Any overnight option. Dawn boat safaris in the first morning light are when gibbons, hornbills, and macaques are most active. No day trip can replicate this.
Practical Notes
- Khao Sok National Park entrance fee: approximately ฿300 for adults, ฿170 for children; confirm whether this is included in your tour before booking
- The pier for Cheow Lan Lake is at Ratchaprabha Dam, approximately 65 km from Khlong Sok village; all tours handle this transport
- Best months: November to April (dry season; jungle walks on dry trails, lake at lower levels exposing more karst base); the wet season (May–October) brings heavy rainfall but the jungle is lush and green, birdlife is active, and tourist numbers drop significantly — still very worthwhile
- Independent visitors can reach Khlong Sok by bus from Surat Thani (the nearest rail junction), Phuket, or Krabi; the bus from Phuket takes approximately 2–2.5 hours
- Leeches are present in the jungle after rain; wear enclosed shoes and tuck socks over trouser legs on hiking days
- Wildlife sightings are never guaranteed; gibbons are heard almost every morning but seen less reliably; elephants cross the lake occasionally but rarely on schedule
- Floating bungalows do not have air conditioning; temperatures drop naturally at night on the lake and the sound of the forest is part of the experience
