The Ngam Islands in Chumphon Province are a very popular and beautiful snorkeling and diving area in the Gulf of Thailand. The archipelago consists of Koh Ngam Yai, Koh Ngam Noi, and underwater rocks, and is famous for its black coral, sea anemones, and large schools of fish. The islands lie approximately 15–20 kilometers off the coast, and the best time to visit is from November to May.

• Koh Ngam Yai: An island that, due to its bird's nest structure, has no sandy beaches. Its main attraction is the "Buddha's Hand," a high cliff with a finger-shaped crack, and small underwater caves.

• Koh Ngam Noi: A rocky promontory in the middle of the sea, inaccessible on foot. It is a popular dive site where you can admire the lush coral reefs and the many schools of fish.

• Hin Lak Ngam (Hin Pae): An underwater rock formation that is a popular spot for deep divers.

-Travel and best time to travel: The best time to travel is from November to May, as the sea is calm and the water is clear then.
