The Similan Islands are a group of nine uninhabited islands located in the Andaman Sea, about 70 km northwest of Phang Nga Province in Thailand. They are part of the Mu Ko Similan National Park and are known for their white sandy beaches, crystal clear waters, and abundant marine life. The islands are named after the word "Similan," which means "nine" in Malay, and are numbered from north to south
. The nine islands are: Koh Ba Ngu, Koh Ba Kang, Koh Ba Laeo, Koh Ba Nai, Koh Ba Nok, Koh Ba Nai, Koh Ba Kho, Koh Ba Mu, and Koh Ba Khao. The Similan Islands are popular among snorkelers and divers, who come to explore the many reefs and underwater rock formations that are home to a diverse array of marine life, including tropical fish, sharks, dolphins, and manta rays. The islands are also home to a variety of land-based activities, such as hiking and camping, and offer a peaceful and natural setting for tourists looking to escape the crowds. In addition to their natural beauty, the Similan Islands are known for their cultural significance. They are home to several ancient ruins and artefacts, and are believed to have been used as a trading hub by the ancient Chinese and Indian empires. The Similan Islands are a popular tourist destination and can be visited by boat from the mainland. The islands are only open to the public from November to May, as the monsoon season makes them inaccessible during the rest of the year. If you're planning a visit to the Similan Islands, be sure to bring plenty of sunscreen, a hat, and a good camera, as the islands offer some of the most breathtaking scenery in Thailand.
