Exploring Khao Sok National Park: Top Activities and Attractions

What to do in Khao Sok National Park: take a long-tail boat across Cheow Lan Lake and sleep on a raft house, float or paddle the Sok River (tubing ฿300–500), walk the Ton Kloi waterfall trail (the first 2.9 km need no guide), join a night safari (฿600–800), and, from December to March, hike to a blooming Rafflesia. Two to three days covers the best Khao Sok activities without rushing.

Below, every activity worth your time, grouped by water, land and village, with prices, seasons and a sample plan.

Overview of Khao Sok National Park

Introduction to Khao Sok National Park

Khao Sok National Park was established in 1980 as Thailand's 22nd national park and covers 739 km² of Surat Thani province. Its significance is simple: it protects one of the largest surviving blocks of evergreen rainforest in southern Thailand, joined to Klong Saeng Wildlife Sanctuary, and it holds Cheow Lan Lake.

The park's natural features: limestone mountains up to 960 m, rivers and waterfalls, caves, and the reservoir with its karst pillars. The activities available split into two areas about an hour apart: the headquarters side (village, trails, river, night safaris) and the lake side (boats, rafts, caves). The visitor center is open daily from 08:00 to 16:30.

Water Adventures in Khao Sok

Exploring Cheow Lan Lake

Boat tours and scenic views are the core of any visit: long-tail boats run from Cheow Lan Pier past the karst pillars nicknamed the "Guilin of Thailand", into side arms and coves, to caves and raft houses. The floating bungalows experience adds a night on the water with dusk and dawn safaris, arguably the single best thing to do in Khao Sok.

Fishing and kayaking opportunities: kayaks come free at most raft houses, and paddling the shoreline at dawn is lovely. Fishing isn't part of standard tours, and rules inside a national park are strict, so ask the raft house before bringing a rod. Swimming off the rafts is normal; wear the life jacket.

Activities on the Sok River

Canoe trips and river tubing are the relaxed side of Khao Sok. A guided canoe trip (about ฿800) drifts under limestone cliffs and overhanging jungle; tubing (฿300–500, about 1.5 hours) needs enough water and is better in the wet season. Bamboo rafting costs around ฿1,200. In the mid to late dry season the river can be too low for a smooth float.

Wildlife spotting along the river: kingfishers, monitor lizards, macaques, snakes on branches, and sometimes gibbons crossing overhead. Best times for river activities: mornings for wildlife and calmer air; June to November for tubing with some current.

Land Adventures and Wildlife

Jungle Trekking and Hiking

Popular trekking routes from the headquarters, with published distances:

• Ton Kloi Waterfall Trail, 7 km along the Sok River. The first 2.9 km, to a ranger checkpoint, need no guide: Wing Hin Waterfall (20 m tall, about 2.8 km), Wang Yao pool and Bang Hua Rat Waterfall (about 3 km). Beyond the checkpoint a guide is required: Bang Liap Nam Waterfall (4.5 km), Than Sawan Waterfall and Tang Nam Gorge (about 6 km), ending at Ton Kloi Waterfall. It has become very busy since the 2023/24 season.
• Sip Et Chan Trail, roughly 4–6 km one way (sources differ) north along the Bang Laen River to an 11-tiered waterfall; bamboo woodpeckers and great hornbills are possible.
• Rafflesia trail, 4.9 km, moderate to challenging, guide required; quieter than Ton Kloi.
• Khlong Pae Nature Trail, 6.5 km, starting 10–12 km east of the village (km 99) and ending at Cheow Lan Lake; guide required.

Guided vs self-guided hikes: self-guided is fine for the first stretch of Ton Kloi; beyond checkpoints and on the other trails, guides are mandatory or strongly advised (a half day costs about ฿600, a full day ฿900–1,200). Safety tips and what to bring: start early, carry 1.5 litres of water, wear shoes with grip, use repellent (leeches in the wet season), keep food away from macaques, and be back before the visitor center closes at 16:30.

Wildlife Watching Opportunities

Common wildlife species in the park: long-tailed macaques and banded langurs around the headquarters, gibbons (mostly heard), hornbills, kingfishers, and many snakes, lizards and frogs along the trails. Wild boar and deer sometimes appear. Elephants are seen from the lake now and then. Tigers haven't been seen for decades.

Best spots for wildlife observation: the lake's quieter arms at dawn and dusk; the headquarters trails at night (reptiles and amphibians are most active in the evening); remote Klong Saeng inlets on private trips. For a dedicated trip, see the Wildlife Explorer tour.

Tips for responsible wildlife watching in the rainforest: keep your distance and your voice down, never feed animals, don't use flash on nocturnal animals, stay on trails, and don't handle snakes or frogs whatever the guide does for photos.

Cultural and Guided Experiences

Guided Tours in Khao Sok

Types of guided tours available: lake day and overnight tours, jungle treks, night safaris, canoe and rafting trips, birdwatching, private wildlife trips, and elephant sanctuary visits outside the park. The benefits of a guided tour: guides find wildlife you'd miss, are required on several trails, and handle lake logistics (boats are hard to arrange on arrival in high season).

How to book a tour: at a tour desk in Khao Sok village (many are in guesthouses), directly with local operators by WhatsApp, or online. Compare the options in Khao Sok tour packages, or look at local desks such as Khao Sok Center Tour.

Visiting Khao Sok Village

Cultural experiences in the village are low-key: family-run guesthouses, Thai cooking classes sold at some hostels, massages, the Buddhist temple Wat Sok Tham Phanthurat a few kilometres out, and the market stop at Ban Ta Khun on the way to the lake.

Local cuisine and dining options: southern Thai curries and stir-fries at small restaurants near the gate (Pawn's Restaurant and Thaiherb are close by), coffee and breakfast at Hungcup Slow Bar next to Coco Hostel, Little Wild Cafe at the end of the main street, and a bakery next to Coco. Accommodation choices: from ฿300 rooms and hostels to resorts from about ฿1,500, plus camping at the headquarters (฿30 per person, tents from ฿225 a night). See where to stay in Khao Sok.

Planning Your Visit

Creating a Multi-Day Itinerary

Suggested itineraries for 2–3 days:

Balancing activities and relaxation: keep one half-day empty for rain, and don't stack a full-day trek before the lake. Tips for a memorable visit: sleep on the lake if at all possible, go out on the dawn boat, bring cash for fees, and leave your big bag in the village.
