Thailand liveaboard recommendations
The best way to dive the Similan and Surin Island national marine parks is by liveaboard. If you are serious about doing the best diving in Thailand then a liveaboard is the only way to go.
The most popular Thailand liveaboard duration is 4 days 4 nights and includes diving at the the Similan Islands, Koh Bon, Koh Tachai and Richelieu Rock. Shorter trips are available that focus just on the Similan Islands or the Richelieu Rock, Tachai and Koh Bon.
There are also short (2 or 3 night) liveaboards to Hin Daeng, Hin Muang, Koh Haa and Phi Phi. These can be combined with a Similan trip to make a complete Andaman sea dive safari.

Pawara is great value and always well reviewed. The dive staff are a cheerful group and the food is excellent. Prices are just a bit cheaper than the competition and include free nitrox. Pawara is often booked up well in advance.
- Best value single cabin
Oktavia has a good price for single occupancy cabins if you are traveling solo. It’s a big boat with lots of space. Oktavia is a step up from the budget boats but still cheap.
- High style liveaboard without the high price
The Junk is very good value for such an iconic boat. Especially if you book early and get a discount.
- 3 day 2 night budget Similan Islands and Koh Bon liveaboard
MV Nangnuan is the cheapest liveaboard. No cabins, you sleep on deck. Does not dive at Richelieu or Tachai.
- 4 days 4 nights Similan Islands and Richelieu Rock budget liveaboard
Dolphin Queen is our choice for the best all round budget liveaboard.
- 3 days 3 nights budget Richelieu Rock liveaboard
MV Andaman is another very cheap liveaboard with 3 day or 6 day trips. Prices include equipment rental.
- 2 day 1 night Similan liveaboard
South Siam 3 offers overnight trips to Similan and Koh Bon. Prices include transfers from Phuket.
- 3 day 2 night Richelieu Rock and Similan Islands liveaboard
South Siam 3 or South Siam 4 have the shortest Richelieu liveaboard trips. These 2 night trips also include the Similans so they are a good choice if you want to dive it all in a short time window.

Oktavia skips the Similan Islands to spend more time at Richelieu Rock, Koh Bon and Koh Tachai.
- 3 days 3 nights budget Richelieu Rock liveaboard
MV Andaman is a cheap boat diving Richelieu and Mu Ko Surin National Park.
Less dived than the Similan Islands but as good as Richelieu Rock. That’s what many divers think about these two submerged pinnacles close to Koh Lanta.
- 2 day 2 night liveaboard to Hin Daeng, Hin Muang, Koh Haa and Phi Phi
Giamani is the best liveaboard diving at Hin Daeng and Hin Muang and if you have 6 days to spare we highly recommend the 6 day trip that is a combo of 2 days south to Hin Daeng/Muang then 4 days north at Similan/Surin.
If you are short of time try one of these one or two night liveaboards

Thailand Scuba Diving
Rated up there with the world’s best dive destinations and certainly Thailands diving crown jewel. Crystal clear water and a variety of underwater topography that most dive destinations cannot offer. A liveaboard is the ideal way to dive all the best Similan sites as well as Koh Bon, Koh Tachai and Richelieu Rock. Underwater photographers will need macro and wide angle lenses on these trips.
Hin Daeng and Hin Muang
Red Rock and Purple Rock, two deep pinnacles frequented by sharks, manta rays and huge schools of fish. Liveaboard trips last 2/3 days and often include dives at Phi Phi Islands, Koh Haa Cave, Shark Point and King Cruiser Wreck. A great alternative or complement to a Similan liveaboard with really varied diving.
Phi Phi Islands
The old backpacker hangout has loads of quality dive sites around stunning karst limestone rock formations. Beautiful soft coral. Leopard sharks, blacktip sharks and sea turtles are all common.
Off the east coast of Thailand in the gulf of Thailand. It hasn’t got the visibility or the diversity of the west coast dive sites but it’s a great destination for lots cheap dives and dive training. Chumphon Pinnacle gets regular whaleshark sightings.
