Khao Sok National Park — Jungle Lodges & Cheow Lan Lake Tours
Thailand's ancient rainforest hides one of the planet's most dramatic landscapes: towering limestone karsts, a flooded valley lake dotted with floating raft houses, and some of the oldest jungle on earth. This guide covers getting there, Cheow Lan Lake tours, jungle activities, where to stay and 2026 prices.
Why Khao Sok?
Khao Sok National Park protects the oldest rainforest in the world — a continuous evergreen jungle estimated at 160 million years, older than the Amazon and the Congo basin. Its signature scenery comes from the dramatic limestone karsts: sheer, jungle-clad cliffs that erupt from the valley floor and, further in, from the flooded waters of Cheow Lan Lake.
The park is also a wildlife stronghold. Elephants, gibbons, Malayan sun bears, wild boar, deer and over 300 bird species live inside its boundaries, and much of it is only reachable by longtail boat or on foot with a guide. It sits conveniently between Phuket, Krabi and Surat Thani, making it an easy 1–3 night detour on any southern Thailand itinerary.
Getting There
Khao Sok has no airport and no train station. Everyone arrives by road, and the gateway is the small village of Khlong Sok on Route 401, right at the park's eastern edge. Travel times are approximate and depend on traffic and the service you pick:
| From | Time | Typical Service | Notes |
|---|---|---|---|
| Phuket | ~3 hours | Shared van / bus | Direct vans run daily from Phuket Town and the airport; most drop you at Khlong Sok. |
| Krabi | ~2 hours | Shared van / bus | Via the 415/401 junction — a short, scenic run north. |
| Surat Thani | ~1.5 hours | Local bus / van | Good stopover if you are coming from the Gulf coast or Bangkok by train. |
Book long-distance vans online in advance during high season (December–April) — same-day walk-ups sell out. If you are continuing from Khao Sok to the Gulf islands, the Surat Thani to Koh Samui route guide covers the onward bus + ferry leg.
Cheow Lan Lake (Ratchaprapha Dam)
Cheow Lan Lake is Khao Sok's showpiece — a 165 km² reservoir created in the 1980s when the Ratchaprapha Dam flooded a valley between the karsts. Dozens of floating raft houses now sit on its turquoise water, and the only way to explore is by longtail boat from the pier at Ban Ta Khun. Most travellers take a day tour, but staying overnight is the experience people remember for years.
🏠 Raja II Raft Houses
The classic lake stay — floating bungalows with decks, full board and sunset views over the karsts.
🛶 Longtail Lake Tours
Guided loops past the karst viewpoints, hidden caves and floating villages. Lunch included on day tours.
🗻 'James Bond' Karst
The lake's most photographed limestone pillar — a mini version of the famous Phang Nga formation, best at sunrise.
💧 Water Levels
Dry season (Nov–Apr) = full, clear water and every cove navigable. Late wet season (Oct) can lower levels.
Day-tour price guide: roughly THB 1,500–2,500 per person including longtail boat, guide and lunch — the range depends on group size, pick-up point and whether you add a cave or hike. Full-day tours usually cover the main viewpoints, a bamboo-raft or cave stop, and swimming-free lake cruising. If the karst scenery tempts you towards Phang Nga Bay as well, see our James Bond Island tour guide.
Jungle Activities
🥾 Day Hikes (1–4 hrs)
Short self-guided loops from the park HQ up to longer guided treks to waterfalls, viewpoints and the lake rim.
🌙 Night Safaris
Flashlight walks or boat cruises after dark to spot civets, owls, frogs and, on the lake, wild elephants on the shoreline.
🐘 Elephant Ethics
Skip riding and show venues. Khao Sok's wild elephants are best seen from raft houses at night — ethical and unforgettable.
🛶 Bamboo Rafting & Caves
Gentle river floats and guided cave trips (e.g. Coral Cave) add variety to a lake-based stay.
A note on elephants: Khao Sok is one of the best places in southern Thailand to see wild elephants — herds regularly come down to Cheow Lan Lake's edge at dusk and night to drink and feed. Guests at raft houses often hear them from their decks. There are also several elephant camps near the park; if you visit one, choose a sanctuary that only observes and feeds, never one offering rides or shows.

When to Go
December to April (dry season) is the best time to visit. Days are hot and mostly rain-free, Cheow Lan Lake is at its fullest and clearest, trails are firm, and wildlife gathers near water sources. This is also peak season, so book transport and raft houses well ahead.
May to November (wet season) brings afternoon downpours, greener jungle, roaring waterfalls and far fewer crowds — plus cheaper rooms. The trade-offs: slippery trails, lower lake visibility after storms, and leeches on any forest walk. Many travellers still enjoy it, but pack leech socks and quick-dry gear.
Safety in the Jungle
🦟 Leech socks
Essential on any wet-season trail. Buy them in Khlong Sok for ~100–200 THB and tuck trousers into them.
🧭 Guides required
Deep-jungle treks and multi-day routes must be done with a licensed guide — the forest is easy to get lost in.
🚫 No swimming in the lake
Cheow Lan has strong currents and submerged trees — boats and raft-house decks only, no swimming.
🐍 Wildlife distance
Give elephants, snakes and macaques space. Never feed monkeys, and keep food sealed at raft houses.

When is the best time to visit Khao Sok?
December to April is the dry season and the best time to visit — warm days, clear water and full lake levels. May to November is wetter but the rainforest is at its greenest; expect rain, mud and leeches on jungle trails.
Is it safe to swim in Cheow Lan Lake?
No. Swimming is not recommended — the lake is deep with strong underwater currents and submerged trees. Stick to boat tours and raft-house decks. On jungle hikes, wear leech socks and always go with a guide in the deep forest.
