Tartain Waterfall: The Remote Jungle Secret of Lipa Noi

Overview

If you are looking for the absolute opposite of a crowded tourist trap, Tartain Waterfall (often spelled Tartan) is your destination. Hidden deep within the rugged mountains of Lipa Noi, this is widely considered the most remote and “untouched” waterfall on Koh Samui. It is not managed by the government but by a local family who has owned this land for generations, preserving a slice of old Samui that many visitors never get to see.

Reaching Tartain is a rite of passage for the island’s more adventurous souls. It requires navigating steep mountain roads and a challenging jungle trek, but the reward is a multi-tiered paradise where you are likely to be the only person in sight.

A Private Jungle Oasis

Unlike the more commercialized falls on the island, Tartain is situated on private property. The family that manages the site has done a remarkable job of balancing accessibility with preservation.

At the entrance, you’ll find a small bamboo hut where the owners collect the entry fee. This fee is essential for the maintenance of the trails, which are carved directly into the hillside.

• Hospitality: The owners are known for their warm Thai hospitality. They often provide visitors with a bamboo walking stick: a tool you will quickly realize is indispensable for the steep climb ahead.
• Amenities: At the base, there are several shaded bamboo pavilions and hammocks where you can relax before or after your hike. A small stall sells cold coconuts, water, and basic snacks.

The Hike: Level 1 to 9

The hike at Tartain Waterfall is a serious undertaking. It is not a casual stroll but a vertical climb through a dense, humid rainforest. The trail is divided into nine levels, each progressively more difficult to reach.

• Lower Levels (1-3): These are relatively easy to access and feature beautiful cascades and small pools suitable for cooling off.
• Middle Levels (4-6): The incline increases significantly. You’ll be climbing over rocks and using tree roots as natural handholds. This section is where the walking stick really earns its keep.
• Upper Levels (7-9): Only recommended for those with a high level of fitness. The path becomes narrow and can be very slippery, especially after a rain shower. Level 9 offers a sense of total isolation and a stunning view of the surrounding mountain peaks.

What to Expect

The waterfall itself is a series of long, sliding cascades that flow over dark, mossy granite boulders.

• Swimming: While there aren’t massive lagoons like at Na Muang 1, there are several natural plunge pools at various levels. These pools are deep enough for a refreshing dip and are incredibly invigorating.

• Nature: Because of its remote location, wildlife is abundant. Keep an eye out for giant butterflies, colorful lizards, and the occasional troop of monkeys in the high canopy.
• Solitude: The greatest draw of Tartain is the silence. Away from the roar of scooters and the chatter of tour groups, the only sounds are the cascading water and the intense hum of the jungle.

Getting There

Reaching the trailhead for Tartain Waterfall is an adventure that requires a reliable vehicle and a bit of nerve.

• The Route: From the main Ring Road (Route 4169), follow the signs toward the interior of the island, heading toward the Secret Buddha Garden. Look for the small, hand-painted signs for “Tartain Waterfall” or “Tartan Waterfall.”
• Road Conditions: The road is paved for much of the way but is exceptionally steep with sharp hair-pin turns. In the final stretch, the road turns into a dirt track that can be difficult to navigate after heavy rain.
• Vehicle Choice: A 4WD vehicle is the safest option. If you are on a scooter, ensure it has a powerful engine (at least 125cc or 150cc) and that your brakes are perfectly functional. Novice riders should not attempt this drive.

Best Time to Visit

Like most of Koh Samui’s natural water features, Tartain is highly seasonal.

Season	Water Level	Difficulty	Experience
Oct - Dec	High	Hardest	★★★★★ Spectacular cascades, but paths are very slippery.
Jan - Feb	Moderate	Moderate	★★★★ Perfect for swimming and exploring all 9 levels.

Practical Tips

To make the most of your visit to this remote hidden gem, keep these tips in mind:

• Footwear: Leave the flip-flops at home. You need proper hiking shoes or sports sandals with a very strong grip.
• Insect Repellent: The mosquitoes here are relentless. Apply a strong repellent before you leave your vehicle and bring the bottle with you.
• Supplies: While the owners sell drinks, it’s wise to bring at least one large bottle of water per person. The humidity in the jungle will dehydrate you quickly during the climb.
• Safety: Always let someone know where you are going. Since Tartain is so remote, cell service can be spotty, and there are few other visitors to help if you take a spill.
