Koh Samui is not just beaches. The island's interior, hidden behind the ring road, holds tropical jungle with waterfalls, rocky trails and viewpoints. It's a parallel version of the island, discovered by those who venture away from the coastline.

Na Muang 1 — Most Accessible

Na Muang is the most famous waterfall on Samui. Located in the island's center, 12 km from Chaweng. Water drops about 18 metres into a natural pool with a distinctive purple-violet hue (from the rock composition). The pool is shallow at the edges and deeper in the center — swimming is popular here.

The walk from the road takes 10–15 minutes on a paved path. There is parking on-site. Best time to visit: morning, before the tourist buses arrive. During the rainy season (October–November), the water flow is at its strongest, but paths can be slippery.

Na Muang 2 — For Hikers

The second waterfall sits higher up the trail from the first — about 1.5 km of uphill forest path. At approximately 80 metres high, it's narrower and taller than Na Muang 1. The trail is moderately challenging: non-slip footwear is essential, but no serious fitness level is required. There are short stream crossings along the way. Swimming is permitted.

The climb from the Na Muang 1 parking area takes around 45 minutes. Plan on 2–3 hours for the round trip to Na Muang 2.

Hin Lad — In the Nathon Jungle

Hin Lad is located near Nathon, the island's administrative center, on Samui's western side. Less touristy than Na Muang, it tends to be quieter. The trail to the falls passes through a small Buddhist monastery. Along the way you'll encounter exotic birds, butterflies and tropical trees. The waterfall drops about 15 metres.

Tarnim — Hidden Gem

The most remote of the well-known waterfalls. Deep in the island's interior, harder to reach. Part of the approach is via a dirt track suitable for motorbike or 4WD. There's a small natural pool for swimming. Because of the difficulty of access, this one draws the fewest visitors — if you want solitude, this is your waterfall.

Trekking and Viewpoints

Samui has several spots with panoramic views of the island and sea. The most accessible are the viewpoints along the central mountain road (Route 4169). At 300–400 metres elevation, these spots offer simultaneous views over several sides of the island.

The ideal time for trekking is morning — before 10:00, before the heat builds. After 14:00, the tropical jungle is hot and humid. Bring water, a hat, sunscreen and closed-toe shoes. Insect repellent is particularly useful during the rainy season.

Practical Tips

  • Transport: a rented motorbike or car is most convenient for reaching the waterfalls. Taxis and songthaews are available but run on no fixed schedule.
  • Entrance: most waterfalls are free; some charge a small parking fee (฿20–50).
  • Safety: don't swim at waterfalls during heavy rain — water levels rise rapidly.
  • Best season: February–April and June–September offer good visibility and moderate crowds.

The Samui jungle is a different island — green, humid, quiet, with the scent of flowering trees and the sound of birds. Thirty minutes from tourist Chaweng, you're in tropical forest that looks entirely untouched.
