Why Visit the Similan Islands
Beaches. The Similan Islands are often referred to as the “Thai Maldives” for good reason. With powdery white sand, coral-rich shores, turquoise seas, and secluded beaches, they are a paradise. The volcanic origin of the islands ensures crystal-clear waters and excellent visibility.
Nature. The lush flora includes eucalyptus, jackfruit, bamboo, and rattan, while the fauna features monkeys, squirrels, langurs, flying foxes, and exotic birds.
A unique feature of the Similan Islands is the presence of giant boulders on the southern and western shores. On Island No. 8, you’ll find a famous 25-meter-high landmark called “Sail Rock”, which has a viewing platform. Climbing it is easy, and the breathtaking views from the top make it worthwhile. This rock is miraculously balanced on a single edge, leading to a fun tourist tradition of placing small branches underneath for support.
Snorkeling and diving. The underwater world of the Similan Islands is incredibly vibrant, boasting stunning coral reefs that are particularly appealing to divers. The Similan Islands are also considered one of the best places for snorkeling. Here, you can swim not only among schools of colorful exotic fish but also alongside sea turtles — a rare and unforgettable experience. Diving is a popular activity not only in the Similan Islands.
