How to Find the Emerald Lagoon in Railay (Trail, Difficulty & What to Expect)
The Emerald Lagoon on the Railay Peninsula is a small natural pool enclosed by steep limestone cliffs and dense jungle. It isn’t an easy place to find, and reaching it requires a bit of effort. When we were in Railay, it actually took us quite a while to figure out where the trail begins. In this post, we’ll explain exactly where to start, what the hike is like, and what to expect once you get there.

Important: This Hike Is Challenging
Before getting into the directions, it’s worth mentioning that the hike to the Emerald Lagoon can be quite challenging.
Much of the descent is steep and uneven, requiring some scrambling over the rocks. There are sections where you’ll need to climb up and down steep rock faces using ropes for support. You won’t be secured, and parts of the trail are muddy and slippery.
If you don’t feel confident doing that, there is still plenty to do around Railay. But if you’re up for a bit of a challenge, read on.
How to Find the Trailhead
Ropes marking the trailhead to Emerald Lagoon in Railay
The hike to the Emerald Lagoon starts about halfway along the path connecting Railay East and Phra Nang Beach.
The trailhead isn’t clearly marked. There’s no proper sign. The only real indication is a few ropes hanging down a steep rock face. We actually walked past it twice before realizing that this was the starting point.
The Trail
Steep rope-assisted descent to Emerald Lagoon in Railay, Thailand.
Right from the beginning, the trail is very steep. Ropes run along almost the entire ascent to help you pull yourself up. The ground is often muddy, and the red dirt will likely stain your clothes. Ours were completely red by the end of the hike.
At some point, the path splits:
Turn left, and you’ll reach the Railay Viewpoint.
Turn right to continue toward the Emerald Lagoon.
After turning right, the trail begins to descend. You’ll need to carefully lower yourself down steep rock ledges using ropes for support. Some sections are almost vertical, and your footing isn’t always obvious.
The viewpoint is only a short detour and offers one of the best views over the Railay peninsula.

The Emerald Lagoon
Once you reach the bottom, the lagoon opens up in front of you. It is surrounded by steep limestone cliffs covered in dense vegetation. The rock walls rise almost vertically around you, forming a circular opening to the sky above.
The lagoon is fed by ocean water, so its water level changes with the tide. During high tide, it fills up, and you can swim. At low tide, the water level drops significantly, and swimming might not be possible.
A Few Practical Tips
We wouldn’t recommend visiting the Emerald Lagoon alone. The climb up and down can be slippery, and it’s safer to go with at least one other person.
It’s also a good idea to wear shoes with decent grip, as the trail is steep, muddy, and uneven in parts.
