Na Muang Waterfalls Trail
Na Muang 1 to Na Muang 2
The island's most popular real hike: a jungle trail from the Na Muang 1 area up to the 80-metre Na Muang 2 waterfall. Roughly 2.7 km round trip with about 260 m elevation gain (one local source), 25-40 minutes each way, with mud, roots, rope sections and a boulder scramble at the end.

The story
This is the standard 'jungle hike' on Koh Samui. From the Na Muang 1 car park a signposted trail branches left toward the upper falls (a separate rough 4WD road also exists). 7 km round trip with ~260 m elevation gain.

The trail is well-trodden but unmaintained: expect exposed roots, mud after rain, slippery rocks, a few steep sections with fixed ropes, and a final scramble over boulders to the base of the 80 m cascade. The reward is a rock amphitheatre with the island's tallest waterfall and a rocky pool (swimmable in moderate flow, less inviting than Na Muang 1). Start before 10:00 to avoid heat and crowds.
Do not attempt in or just after heavy rain: flash-flood risk is real, and Na Muang 2's moss-covered rocks have a documented history of serious accidents - never climb the rock face. Entry usually free with ~20-30 THB parking; one source reports a 50 THB fee. Bring at least 1 L of water per person, insect repellent, and shoes with grip (no flip-flops).
Good to know
- Daily, roughly 08:00–17:00. Go in daylight only; the trail to Na Muang 2 is steep and slippery.
- Free · Free entry at Na Muang 1. Parking about 20 THB (scooter) / 60 THB (car).
- Morning (before 10:00); Dec-Jan balances flow and trail safety
