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!

I was looking for an adventure, but instead I found a family that loves diving as much as I do.
Everyone on the crew was great and made this experience very special. Great group of divers to share this trip with. I felt like I have known them for a long time. Astounding rock formations at Elephant Head. The huge amount of marine life at Richelieu, that is impossible to describe. Must see for yourself. The beauty of Similan. Special thank you to Fei. You will always have my respect and admiration.

Fei, the best dive guide ever. She was amazing. Great diving locations, north and south of Andaman in one trip. The big family liveaboard experience.

A fantastic dive tour of the Andaman Sea islands and dive sites.
I selected Gentle Giant because of its itinerary. Most boats either dive the northern or the southern Andaman Sea. In the same trip, Gentle Giant visits all the most important and beautiful dive sites on the Indian Ocean coast of Thailand, both in the north and south. From the Richelieu Rocks teeming with life, through the fifty-plus meter visibility of the Similian Islands, to the sharks of Koh Phi Phi, our guides, fluent in both English and Mandarin, put us on all the best spots! The diving was amazing! The staff and crew were super friendly and helpful, and the food was fresh, savory, and abundant, with Thai, Chinese and Western selections. I look forward to diving again with Gentle Giant in the future.
