Overview
Tartain Waterfall (น้ำตกตาเตียน) is not for the faint of heart. Located deep in the central mountains of Koh Samui, near the Secret Buddha Garden, it offers what many consider to be the most physically demanding short trek on the island. This is a family-run site that has preserved its “raw” jungle feel, eschewing concrete paths for rope-assisted scrambles and bamboo railings.
The trek to Tartain is often described as a “jungle gym” experience. You’ll spend more time using your hands than on many other trails, hauling yourself up steep muddy inclines and balancing on narrow ridges. The reward at the top is a beautiful, intimate waterfall with a refreshing plunge pool and a series of hammocks and swings that feel like a private treehouse in the clouds. If you want a true adventure that tests your grip and your grit, Tartain is the trail for you.
Trail at a Glance:
- Distance: ~1.2 km round trip (vertical focus)
- Duration: 30 min ascent; 2 hours total
- Difficulty: Challenging (Technical/Steep)
- Highlights: Rope climbs, bamboo forest, jungle plunge pool
- Entry Fee: 100 THB (includes walking stick)
Trail Details — The Climb
The trek begins at a small mountain hut where you pay the 100 THB (~3 USD) entry fee. The local staff will provide you with a bamboo walking stick, which you should absolutely take—it will be your third leg on the slippery descent.
Level 1 to 5: The Forest Walk
The first few hundred meters are a steady incline through dense tropical forest. You’ll pass under giant banyan trees and through patches of bamboo. Even in this “easy” section, the humidity is intense, and the path is narrow.
Level 6 to 9: The Vertical Scramble
The trail quickly becomes “technical.” You will encounter several sections where the incline is nearly 45 degrees. Thick nautical ropes are tied to trees to help you pull yourself up. This is the “Level 9” challenge that Tartain is famous for. You’ll be climbing over rocks and through tight gaps in the vegetation, often with the sound of the waterfall thundering nearby but hidden from view.
The Summit Reward
After the final rope section, the trail levels out onto a series of wooden platforms built directly into the cliffside.
- The Plunge Pool: At the top, there is a natural basin where the waterfall drops about 10 meters. The water is ice-cold and incredibly refreshing after the exertion of the climb.
- The Jungle Swings: The family that maintains the site has built several sturdy jungle swings and hammocks. You can swing out over the valley, with the vast Samui jungle spreading out beneath your feet.
- Relaxation Decks: There are small bamboo huts and benches where you can sit and listen to the forest. Since this is one of the island’s most remote spots, you’ll often have this paradise to yourself.
Difficulty & Duration
| Activity | Time | Difficulty | Terrain |
|---|---|---|---|
| Ascent | 20-30 min | Challenging | Vertical, ropes, mud |
| At the Falls | 1 hour | Relaxing | Rock pools, hammocks |
| Descent | 25 min | Moderate | Slippery; requires sticks |
Despite its short distance, the Tartain trek is rated as Challenging. It requires significant upper body strength for the rope sections and good balance for the slippery return journey. It is not recommended for those with mobility issues or a fear of heights.
Getting There
Tartain is located in the central interior, near the highest point of the island.
- The Mountain Road: The journey starts from the road opposite Wat Khunaram (the Mummified Monk). Follow the signs for “Magic Garden” or “Secret Buddha Garden.”
- The Turn-Off: Continue past the Magic Garden for another 2-3 kilometers. Look for the colorful hand-painted signs for “Tartain Waterfall” or “Jungle Gym.”
- Vehicle Requirements: The road is paved but extremely steep. Do not attempt this on a weak 110cc scooter or a car with poor brakes. A 4x4 or a powerful motorbike is essential.
- Parking: There is a small dirt area at the base of the trail where you can leave your vehicle.
Best Time to Visit
Like most mountain waterfalls, Tartain is highly dependent on the rain.
| Season | Months | Rating | Condition |
|---|---|---|---|
| Post-Rain | Dec – Feb | ★★★★★ | Perfect flow; greenest jungle; trail is firm. |
| Monsoon | Oct – Nov | ★★★ | Maximum flow; trail can be dangerously slick. |
| Hot/Dry | Mar – June | ★★ | Water may stop; trek is still good for exercise. |
| Summer | July – Sept | ★★★★ | Good for a cool dip; manageable trails. |
Practical Tips
- Footwear: Wear proper hiking shoes or boots. Sandals are not safe for the rope sections.
- Gloves: If you have sensitive hands, a pair of light gardening gloves can help with the rope friction.
- Hydration: Bring plenty of water. You will sweat significantly on the ascent.
- Leeches: During the monsoon season, leeches can be present in the damp leaf litter. Check your ankles at the top.
- Descent Safety: Use the provided bamboo stick. The descent is often harder than the climb because of the slippery mud.
