Tremendous experience, to highlight the group and the excellent work of the crew
The new friends after days of living together and the net dives and purple rocks and "the hand of John", although they were all very good and left us unforgettable memories, such as the explosion of life in the wreck of the King Cruisier

Amazing…couldn’t of asked for a better trip
Cannot thank our crew and the staff members on board enough. They made our short stay unforgettable. Everyone so friendly, professional and made us feel like part of the family. Every meal was incredible! And there was plenty of! Our dive guide was amazing and we were lucky enough to see elusive guitar sharks…truly incredible. The rooms were simple but comfortable. Each day we had a dive briefing, a very clear plan of action so we knew what to expect. Truly cannot recommend enough and we rave about the Gentle Giant to everyone who asks about our Thailand honeymoon.

Varied beautiful diving
With great dives in the north and south in the Andaman Sea, this trip offered varied dives from beautiful coral reefs to always beautiful schools of fish and highlights such as leopard sharks and seahorses. Despite some poor visibility, the dives were relaxed and quite beautiful.

Moray Eel vs.Triggerfish
I booked a tour with Gentle Giant and MV Raga to the Similan Islands. Both tours were fantastic. Great staff and lots of sea life to see. The dive sites are varied and, for me, among the most beautiful ever. Special thanks to the guides, Sasha, Spice, and Freshy. Thanks to them, I got to see lots of cool things that I would otherwise have missed. The whole staff does a great job, and on every tour, the friendly owner stops by to ask if everyone is satisfied.

Best liveaboard experience!
We did 10 dives in 3 days to the surrounding islands of Phuket, and it was excellent! We saw 3 shipwrecks, lots of coral, sharks, eels, rays, other animals and millions of fish.. very satisfying! The accommodations were nice and the food was beyond excellent. All the guides were very nice and the boat boys were amazing in helping us get ready, and on/off the boat for every dive. An incredible deal for the price!
