Overview
Heading for the northern Andaman Sea
Diving Liveaboard Similan Richelieu Rock
Embark on an unforgettable journey to discover the underwater treasures of Thailand’s northwest coast during our 4-days Similan liveaboard cruise departing from Khao Lak or Phuket. From the white sandy beaches of the Similan Islands to the majestic Richelieu Rock, including Koh Tachai and Koh Bon, you will explore all the world-class diving sites of this region.
Immerse yourself in a spectacular underwater landscape, with granite rock formations and sedimentary reliefs adorned with an incredible diversity of hard and soft corals, as well as giant gorgonians. You will be amazed by the abundance of marine life, with hundreds of endemic species and stunning schools of fish accompanying each of your dives. Encounters with pelagic creatures are common, especially with majestic manta rays and impressive whale sharks, particularly at Richelieu Rock, ranked among the world’s top diving sites.
More about the destination
Why us
Our own boat, since 1997
Why dive the Similans with Andaman Scuba
Our own boat
The Bunmee 4 is ours: a 29-metre steel liveaboard launched in 2016 and refitted in 2023, 20 divers at most in 10 air-conditioned cabins with private bathroom. We run the cruise, the crew and the dive team ourselves; nothing is chartered.
Since 1997
Andaman Scuba has been established in Phuket since 1997 and in Khao Lak since 2004, facing the Similan Islands: more than 25 years of liveaboards on these sites.
Small groups underwater
Four to five divers per guide at most, grouped by level and air consumption, with a full briefing before every dive.
The whole northern route in four days
Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock and the Surin Islands: 15 dives, night dives included, on the sites where manta rays and whale sharks are seen in season.

Testimonials
« What more can you say when you go to Thailand to dive »
What more can you say when you go to Thailand to dive. A feast for the eyes. Sites rich in hard and soft corals. Oh yes, we ate really well, thanks to the cooks as well as the crew and the guides. Beware of little Tom who introduces you to Thai boxing. He is lively, fast and too kind. I would start the adventure again with my daughter (Level 2 diver). That’s for sure.

« I just went on my first diving cruise »
I just went on my first diving cruise. And honestly, I had a waking dream. You were perfect. The boat is great, the organization is ideal, the food is divine, and the entire crew is so attentive and just sensational. I hope that life will allow me to come back for another diving cruise with you. A huge thank you to the whole team. See you soon 🤞🤞

« The best company I have ever travelled with »
The best company I have ever travelled with. It’s one thing to say that everything is ace, but the staff are so warm, kind and helpful that it’s beyond words. I accidentally left my wetsuit on the boat. After a few phone calls they had already arranged to be at the airport with a transfer. I can only recommend🙏😊
Horváth G. · November 2024
« THANK YOU »
THANK YOU! Thank you for this first diving cruise which was exceptional. From start to finish everything was perfect. The INCREDIBLE food, the little touches from the staff, and above all, the safety during the dives. They know the diving spots like the back of their hand, so there are lots of nice surprises waiting for you.
