Similan & Richelieu Rock Liveaboard


The Similan Islands have been world famous diving destinations for decades. The waters around these distant islands are amazingly clear and aquatic life very diverse. The paradise like islands are like straight off a postcard and you also get to visit these pristine beaches. One of the best things about these trips is the everyday changing environment. You get to dive among granite boulders, deep pinnacles, limestone walls, soft and hard coral reefs and wrecks.

All the dive sites lay northwest from Phuket and can be described as Thailand northern sea-area. Every site belongs to a Marine National Park where fishing is forbidden. In wintertime from November till April the seas are calmest and the area is open for diving. During summertime from May until November the area is closed due to the monsoon season.

If you wish to embark on one of our Similan trips please contact us and we can together find the best deal for you!



Nine islands with dozens of dive sites. Similans are not so famous for their coral, but for their boulders. Huge granite formations with canyons and swim troughs make these sites memorable. And it just can't be stated enough, the visibility on some of the sites is outstanding - where else can you see sunlight play around in the bottom at 30 meters? Several of the dive sites offer a good chance to see reef sharks and turtles, others have frogfish or ribbon eels inhabiting them. You also get to visit the beaches and viewpoints of some of the stunning islands.

Depth: 5 - 50 meters
Visibility: 20 - 40 meters


Favourite dive sites for many, the islands of Koh Bon and Koh Tachai offer fantastic soft coral reefs and pinnacles with great chances to see Manta Rays or Whale sharks. Both destinations are known cleaning stations where big and small fish gather to have cleaner wrasse and bannerfish clean their wounds and remove their parasites. Other fish usually seen here are big groupers, napoleons, octopus, schools of jacks or barracudas and tunas. Especially snorkelers have a fair chance of seeing sharks.

Depth: 10 - 35 meters
Visibility: 20 -30 meters


The trip goes all way north to Surin Islands and to the most famous dive site in Thailand: Richelieu Rock. Named by Jacques Cousteau this horseshoe shaped rock formations is an oasis for fish in the middle of nothing. Filled with soft corals and anemones it is one of the most colorful dive sites there is. Macro life is abundant and fills cracks in the rock. Harlequin shrimps, seahorses, ghost and cleaner pipefish, egg cowries and slugs can be seen on one dive but we usually do at least three. There is big stuff like barracudas, jacks, cuttlefish, octopus, huge scorpion fish and then there is the truly big animals - Richelieu Rock is best known for its Whale shark sightings!

Depth: 5 - 30 meters
Visibility: 20 - 30 meters


On a Similan safari we usually dive at least one wreck but there are a few. Boonsung is the most common one as it thrives with life and is not very deep. Sea Chart 1 is a big cargo ship that sunk in 2009. It is still in one piece but quite deep in 30+ meters. Tuna Wreck is an old fishing vessel sunk on purpose for the divers to explore.

Visibility: 10 - 20 meters


From Phuket there are dozens of liveaboard trips to this destination. In no case do we ever recommend doing a daytrip to the Similans, because it will be a long and an expensive day - and you will miss out on the best sites. So please reserve at least 3 - 4 days for this destination and you will get to dive in the best sites in Thailand.

Safaris depart every week - almost every day! There are many different kinds of boats but all do almost the same spots. We have listed below the best options for different budgets and left out the boats that can be considered dangerous or uncomfortable. This way you get the best and don't need to rely on luck!

Similan safari starts in the afternoon around 15:00 from Phuket (or 18:00 from Khao Lak) when you get picked up from your hotel and taken to the boat (Tablamu Pier). On board you will be given a cabin and it's time to have an equipment check. We will depart after a welcoming speech and a boat briefing. Every day several tasty meals are served mixing western and Thai kitchen. Between dives you can relax in your cool cabin or catch some sun on the hot sundeck. In the evening it's time to exchange diving stories!

Below You can find all our trips listed with prices. All prices are in Thai baht per one customer. Marine park fees are separate after the safari price, and Marin park fees are paid by cash in the boat at departure day.
