The Similan Islands have been part of Thailand’s protected Mu Koh Similan National Park since 1982. Their name, ‘Similan,’ comes from the Malay word ‘sembilan,’ meaning ‘nine,’ referring to the nine islands in the archipelago. Historically, the islands were used by fishermen, but the rapid growth of tourism and the awareness of their environmental significance led to the area being designated as a national park. The islands are now protected to ensure that their unique ecosystems are preserved for future generations.
The Similan Islands have also become famous as a marine conservation area. Due to their protected status, the islands offer some of the best-preserved coral reefs and marine environments in the region, attracting not only divers and snorkellers but also researchers and marine conservationists.
The Similan Islands are only accessible during certain months of the year. The national park is typically open to visitors from mid-October to mid-May, with the rest of the year being reserved for environmental preservation. During the off-season, the islands are closed to visitors to allow the marine life to regenerate.
Given the popularity of the Similan Islands, tourism is carefully managed to prevent environmental degradation. Visitors are encouraged to respect nature by adhering to eco-friendly practices, such as not touching or disturbing marine life, not leaving trash behind, and following park regulations.
Beyond the incredible underwater life, the Similan Islands are also home to unique wildlife, including various species of birds, lizards, and the endangered green sea turtle. The islands provide a sanctuary for these creatures, making it a haven for wildlife enthusiasts.
Getting to the Similan Islands from Phuket is relatively straightforward. There are several ways to reach the islands, with the most popular being by boat. Most visitors choose to join a day trip or overnight liveaboard tour to the Similan Islands, which are organised by a variety of tour operators in Phuket.
A typical day tour to the Similan Islands departs from the mainland in the early morning, with the boat ride taking around 1.5 to 2 hours to reach the islands. Once there, you’ll have time to explore the beaches, snorkel, or dive at the top sites before heading back to Phuket in the late afternoon.
