Overview
The Hin Lad Waterfall Trail is one of the most rewarding short hikes on Koh Samui — a riverside path through dense tropical rainforest that starts at a Buddhist temple and ends at the island’s second-largest waterfall with natural swimming pools at multiple levels.
At just 2.6 km round trip with 130 meters of elevation gain, it’s accessible to anyone with moderate fitness. But the trail feels far more adventurous than its stats suggest — you’ll navigate tree roots, boulder sections, river crossings, and increasingly wild jungle as you climb toward the main cascade.
The combination of temple, jungle, and waterfall makes this unlike any other hike on the island. And it’s completely free.
Key facts: 2.6 km out-and-back · 130m elevation gain · 30-40 min each way · Moderate difficulty · Multi-tiered waterfall with swimming · Buddhist temple trailhead · Free · Near Nathon

The Route — Step by Step
Temple grounds (0 km)
The trail begins at Wat Namtok Hin Lat, a small forest monastery. Explore the peaceful gardens, Buddha images, and meditation areas before starting the hike. Two paths lead from the temple — take the right path, which is easier, better marked, and follows the river.
Concrete steps to jungle (0-0.1 km)
The first ~20 meters are concrete steps descending toward the river. This is the only paved section. Beyond this, the trail becomes entirely natural.
Riverside path (0.1-0.6 km)
The path follows the river upstream through dense evergreen rainforest. Terrain is a mix of dirt, tree roots, and sandy patches with moderate hills throughout. You’ll pass several lower plunge pools — good for a quick dip on the way up or down.
Boulder section (0.6-1.0 km)
The trail gets wilder. Expect larger rocks to navigate over, fallen trees to duck under, and spots where the path splits with unclear markings. The river is always on your left — use it as a guide. The canopy thickens and the jungle sounds intensify.
Final approach (1.0-1.2 km)
The last section involves navigating very large boulders — this is the toughest part. These rocks can be difficult for children or anyone with knee issues. The sound of the main waterfall grows louder as you approach.
Main waterfall (1.2 km)
The trail ends at the base of Hin Lad’s primary cascade — a multi-tiered waterfall dropping approximately 30 meters over granite boulders into a large natural swimming pool. Above the main fall, additional tiers continue upward, but most hikers stop at the base pool.
Swimming Spots
One of the best parts of this trail is the water access at multiple levels.
Main waterfall pool
The large pool at the base of the primary cascade — the main destination. Deep enough for swimming, surrounded by smooth boulders perfect for sitting and drying off. The water is cool and refreshing, especially welcome after the uphill hike.
Lower plunge pools (3-4 pools)
Several pools at different levels below the main waterfall, accessible along the trail. These are smaller and shallower but often less crowded. Good for a quick cool-down during the hike.
Upper tier pools
Above the main falls, additional pools exist at various cascade levels. Accessing these requires scrambling over rocks and is less straightforward.
Swimming conditions: Pools are fullest during and after rainy season (September-December). During dry season (February-May), water levels drop and pools may be shallow. Always check depth before jumping — rocks can be hidden beneath the surface.
The Temple Start — Wat Hin Lad
The trailhead doubles as a cultural attraction. Wat Namtok Hin Lat is an active forest monastery worth exploring for 15-20 minutes before or after the hike.
What to see
- Garden paths with tropical plants and water features
- Buddha images set in natural niches among boulders and jungle
- Meditation areas — simple shelters for sitting practice
- Resident monks who offer informal meditation workshops
The temple is busiest on weekends when Thai families come for merit-making and picnics. Weekday mornings are most serene.
Flora and Fauna
The trail passes through dense evergreen tropical rainforest within the Koh Samui Nature Reserve. The heavy canopy, river habitat, and temple grounds (where hunting is forbidden) create a haven for wildlife.
Vegetation
- Towering dipterocarp and tropical hardwood trees
- Dense bamboo groves
- Vibrant ferns and palms lining the trail
- Epiphytic orchids on canopy branches
- Tropical fruit trees visible along the path
- Creepers and vines crossing overhead
Wildlife
- Butterflies — diverse species, especially near the water
- Lizards — monitor lizards and smaller species on rocks and tree trunks
- Birds — kingfishers, sunbirds, bulbuls; best in early morning
- Insects — the jungle soundscape is dominated by cicadas and crickets
Trail Running
Hin Lad has gained recognition in the trail running community. Great Runs lists the waterfall path as a running route — 1.2 km with 130m of hill training potential.
Events
The Samui Festival Marathon and Trail 2019 used the Hin Lad area for its 35 km trail race. The annual Samui Trail race (registered with ITRA — International Trail Running Association) covers similar jungle terrain in southern Samui with distances from 7 km to 55 km.
The trail’s combination of steady elevation gain, varied terrain, and natural shade makes it excellent hill training — though the rocky sections demand careful footing at speed.

2.6 km round trip (1.2 km each way) with 130 meters of elevation gain. Allow 30-40 minutes to reach the main waterfall and 1.5-2 hours total including swimming time.
Is the Hin Lad trail difficult?
Moderate. The sustained uphill on uneven terrain (roots, rocks, mud) makes it more challenging than a paved path, but it’s manageable for anyone with basic fitness. The final boulder section near the waterfall is the hardest part.
Do I need a guide for Hin Lad?
No — the trail is self-guided and free. Take the right path from the temple entrance and follow the river upstream. The path gets vague deeper in but the river serves as a reliable guide.
Can I swim at Hin Lad Waterfall?
Yes — there are 3-4 natural pools at different levels along the trail, plus a large pool at the base of the main waterfall. Pools are fullest September-December.
How does Hin Lad compare to Na Muang trail?
Hin Lad is quieter, more atmospheric (temple start, dense jungle), and feels more adventurous despite being shorter. Na Muang 1 is much easier (flat 100m walk) with a bigger swimming pool. Na Muang 2 is harder and taller (80m). Choose Hin Lad for jungle immersion; Na Muang for dramatic waterfalls and easier access.
Is there an entrance fee for Hin Lad?
No — the trail, temple, swimming, and parking are all completely free. Donations to the temple are welcome.
