Are you ready to embark on a unique adventure to discover the Similan Islands on your next holiday to Phuket? Read on to uncover why a day trip to these extraordinary islands is a must-add to your Phuket itinerary.
What are the Similan Islands?

The Similan Islands, a unique archipelago established as a national marine park in 1982, are a must-visit for any nature enthusiast. The name ‘Similan’ originates from the Yawi dialect, meaning ‘nine, ‘which initially referred to the number of islands in the group. However, in 1998, two more islands were added, bringing the total to eleven.
The archipelago is 84 km northwest of Phuket and can only be reached by boat. Unfortunately, no regular ships go to the islands, but there are tour packages, private boat charters, and seasonal ferries during the dry season.
During the dry season, the best time to visit the archipelago is from November to May, when the waters are calm and visibility is best. However, during the monsoon season, the Similan Islands are closed to tourists from June to October.
Commercial fishing is prohibited in its waters as a national marine park, making the marine ecosystem abundant with most of Southeast Asia’s oceanic marine species. Because of this, the archipelago’s dive spots are its main draw, attracting amateur and professional divers worldwide.
Thailand has taken significant steps to preserve the natural beauty of the Similan Islands. One such measure is restricting the number of visitors, with only 3,325 allowed daily. This ensures that each visitor can enjoy the peace, tranquility, and marine adventure that the islands offer without the risk of overcrowding.
To get there, you can take a tour boat from the coastal area of Khao Lak during the dry season. This area is closest to the archipelago, offering the shortest travel time over the waters. But of course, it also depends on the kind of boat, with travel time between 45 minutes for speed boats or yachts to 3 hours for slow ships.
For liveaboards, boats typically leave Chalong Pier or Rassada Pier and travel to several archipelago islands over two to four days.
A private yacht charter can depart from Chalong Pier or the Ao Po Grand Marina for the ultimate luxury. It can also take a custom or tailored route that fits your preferred itinerary.
