Koh Lanta Snorkeling

Koh Lanta is a peaceful island located in the Krabi province, and it’s known for having some of the healthiest coral reefs and diverse marine life in Thailand. The famous Emerald Cave is a must-visit snorkeling site, where you can swim through a dark cave and emerge into a hidden lagoon. Koh Rok and Koh Haa are also popular snorkeling spots, if you are lucky, you might even spot some sea turtles!

Emerald Cave

The Emerald Cave will likely be the highlight of your snorkeling trip in Koh Lanta! This cave is located on the west coast of Ko Muk island and is accessible only by boat and requires a swim through a narrow and dark passage of about 80 meters in length. Once you emerge at the other end of the passage, you are rewarded with a stunning sight of the emerald-colored waters and white sandy beach.

It is a unique experience that is not to be missed! Depending on the time of year you go, the swell is variable. When we went, it was quite strong, so it was tiring to swim back through the passage after visiting the emerald cave.
