General Info

It is an archipelago that consists of 40 islands, suitable for both snorkeling and scuba diving.

Islands for snorkeling include Koh Ngam Noi, Koh Matra, Koh Thonglang, Koh Rangkajiu, and Koh Lawa. And islands for scuba diving include Koh Ngam Noi, Koh Ngam Yai, and Koh Lak Ngam.

This national park is the first place in Thailand that hosts an underwater nature trail. One of the trails is for scuba diving (at Koh Lak Ngam). The other two are for snorkeling (at Koh Matra and Koh Ngam Yai). All of which have underwater information signs, and tourists will receive a guide sheet to lead the way.

Most islands are small rocks without residence, except for some islands where there are huts of locals who get concessions to collect swiftlets’ nests. There are only two islands that have accommodations for tourists: Koh Matra and Koh Kula. On Koh Matra, there is only one accommodation called Baan Lung Khao, while on Koh Kula are accommodations provided by national park and camping grounds.

The park office is on the mainland, where nearby is the Thung Kha nature trail. You can take a boat tour to see the mangrove forest. At night, you can take a boat ride to see fireflies at Tha Taphao Canal.
