The Similan Islands are known to be the location of the best diving spots in Thailand. Since the 1990s, liveaboards have been present in the central Similan Island chain, which includes Koh Bon, Koh Tachai, and Richelieu Hill. Some tours also stop about 100 km north of Similan on the Surin Islands. 

What Are Similan Islands Liveaboards?

To fully enjoy a trip to the Similan Islands, you should consider spending your whole time on a liveaboard, better yet, you should join a liveaboard tour. Liveaboards will take you to the best and most popular diving spots throughout the islands. Whether you’re ready to splurge or are following a tight budget, you can surely find a liveaboard that fits your finances.

Similan Islands liveaboards typically run from November through May. 

Liveaboard dive tours take divers to the most well-known diving spots found in Thailand. These tours are quite popular, as they afford visitors an easy way to access all the islands, including the remote ones. A dive tour is also the best way of getting quality dives. Some tours allow visitors to experience ten dives in the course of three days, with one of them being a night-time dive. A liveaboard tour is also a perfect opportunity to test out your diving skills.

The boat will take you to different dive sites throughout the day according to the circumstances and the weather. Unlike staying in a regular hotel, liveaboards allow you go to more spectacular dive sites because the ship will not waste time onshore. 

Your vessel will only park overnight in a spot and move to the nearest place during the day. Between dives, there is a lot of time to relax or study your next dive site and its inhabitants.

When you dive, a divemaster or instructor leads you to a group. If you’re a beginner, you will also be partnered with a dive buddy to make sure that you are protected and safe.

Thailand’s Similan Islands are blessed with a wonderful location in the beautiful Andaman Sea. These little slices of tropical paradise are far enough from the mainland to give visitors the feeling of being far from it all, but not too far for it to become entirely inaccessible. 

This section of the Andaman Sea offers a number of other exciting locations on top of the Similan Islands, which provide a world-class diversion. 

For those who want to dive at places in the Similan Islands but also want to take part in trips towards the world-renowned Richelieu Rock, they can do everything on one cruise, and even stop to see Koh Tachai and Koh Bon Manta Rays. 

It is generally thought that the best scuba diving in Thailand takes place on the Similan Islands and Richelieu Rock islands (which includes Koh Tachai and Koh Bon). 

Most people go on day trips, but the Similan Islands are certainly the best way to enjoy more than 20 world-class diving spots on cruises. Diving has been extremely popular in Thailand for several years, taking place both on the eastern and western coasts of the world. 

The west bank is next to the Andaman Sea & the Indian Ocean, making marine life in this area is extremely diverse. There are a lot of Similan liveaboards to choose from, and there is something that fits virtually any budget and luxury level. 

Tours may vary. Some tours may take as little as two days and one night, while some tours may last for more than a week. The diving experience is open to all scuba divers, regardless of the level of experience. Both novice and expert divers are sure to enjoy their stay at their chosen tours.
