Entrance to the Emerald Cave

Inside the Emerald Cave
Marvel at the dramatic scenery of limestone karst islands and snorkel around the islands of Ko Lanta’s National Marine Park. Jump from the long tail boat into the warm crystal clear waters of the Andaman sea and discover fantastic marine life.
Even if you’re not so interested in getting in the water, the trip is well worth it simply to enjoy the amazing island scenery. The islands are close together and your boat will sail amongst them for a truly unique experience – revealing the wonders of the Andaman Sea.

View from the beach at Ko Ngai
While most of the tour is on the boat, most operators will also stop at Ko Ngai where you can walk along the beach or stretch out on the sand and work on your tan. There’s also a few resorts on the island so bring along a few baht so you can have an ice cream or refreshing fruit shake!
The 4 Island Tour is a must on your visit to Ko Lanta. If you’re staying in Kantiang Bay then boats leave directly from Kantiang Beach. Most tour operators will offer long tail trips but you can also inquire about speedboats.
Simply Life Tour offer private longtail charter boat trips.
