The Similan Islands are a beautiful chain of islands off the coast of Thailand. The islands are surrounded by white sandy beaches and are home to a rich marine biodiversity, which is why they are a popular destination for scuba divers. The diving here is fantastic, with crystal clear waters and more than 50 dive sites that offer something for everyone, from beginner divers to seasoned professionals.
While it is not the easiest place to get to, it is certainly worth it when you arrive, as The Similan Islands is one of the best diving spots in Southeast Asia.
These nine small islands off the western coast of Thailand have hundreds of coral reefs and are home to an abundant variety of marine life, including rainbow-colored fish, sea turtles, and more. It is hard to choose just one island to focus on, but Pinnacles is a great place to start. Especially during the less-crowded off-season months. At Pinnacles, swimmers can access the water via a natural tunnel that connects to the open ocean.

- Koh Bon
The Similan Islands are a group of islands distributed between the Andaman Sea and the Strait of Malacca.

- Koh Rang
Although Koh Rang is smaller than the nearby islands, it is famous for its colorful coral and marine life. The best time to go is when the weather is clear, as it is during the monsoon season that the island is most popular among tourists, and there are fewer chances to see the sea life.
