4 Islands: Koh Ngai, Koh Mook, Koh Kradan & Koh Chuack: The islands belong to Trang province. But can easily be reached by speedboat from Koh Lanta. Koh Ngai is covered with a lot of hard corals around the island and it is good for people who like shallow water. Koh Mook is not famous for the corals reefs but it’s has it own attraction. The Emerald Cave is the biggest attraction of the trip.

You need to swim into the cave and it is very dark but our guide will lead you safely through the cave. When you are in the cave you’ll find out that you have a feeling of entering into a paradise.

Koh Kradan is very famous for underwater weddings in Thailand. Every year many couples get married here. It has a very nice beach and you may do snorkeling from the beach as well too. Lunch will be served on the beach.

Koh Chuack is actually not an island, but just a big rock. It has gotten its name from a Thai word which means rope. Because usually the sea around the rock has a very strong current and many Thai tourists can’t swim well so the guide has to tide a long rope at the back of the boat and let them hold on to it for snorkeling.
