Deep Andaman Queen
Do it!
The Deep Andaman Queen was the best of diving the Similan and Surin islands. Their infrastructure gives you the best possible dive experience. The only challenge I had was getting on and off... Read more
the Liveaboard on the dives. It challenged me in every aspect with different scenarios at every sites. The crew was very accommodating and will pair you with your experience level. The staff was nice and the instructors are very thorough on their teaching capabilities. I have over 1000+ dives as a recreational master diver and dove in 7 different seas and I’m impressed with their instructors. So, if you thinking of doing an Advanced course, do it with them. You get the maximum dives and experience what you learn with the instructor and they will make sure you understand the skills. The food was good and plentiful. My favorite night was Hot Pot and Korean BBQ night. My favorite dive sites: The Dome, Richelieu Rock and Woosung Wreck. The best part of diving with Deep Andaman Queen is that there are 3 land expeditions. One is a sunset cruise around Similan island and 2 beach hikes with one that has a spectacular views.

ck looked after us perfectly, took very good care of us and also repaired my fin super quickly when it broke. Thanks to the good planning, we were alone at many spots and saw sharks, rays, schools of barracuda and, above all, beautiful, intact reefs. The food was great and we grew fond not only of the crew but also of the other guests. We look forward to seeing you again
