Solid dive trip!
Great dive trip! The boat is well-organized and has lots of nice touches - hot towels after the dives, well-stocked medical kit, great snacks and drinks in between dives, just to name a few. The boat and dive crew are top-notch, and conservation- and safety-focused. Highly recommend

The perfect first liveaboard
Richelieu is definitely the best dive spot, and the people are all so nice. I didn't feel any discomfort during the trip because all Blue Dolphin managers are very kind and helpful.

Great liveaboard with Blue Dolphin!
Great liveaboard experience. Rooms are comfortable. The service and staff were amazing. You definitely don’t loose weight as the food is superb!! They are detailed oriented - like when you finish a dive they have hot little towels waiting for you. They also have detail items for cameras - like special towels for cameras and air to dry them. Dives were great. Everyone on the boat has a smile and is making sure that everyone is happy. Highly recommend. We are seasoned divers and have done multiple liveaboards- and this one stood out for us.

Dive, eat, sleep, repeat!
This liveaboard exceeded our expectations. The crew went above and beyond to give us the best trip possible, even with some crummy weather. Pit was an awesome dive master and helped us get our advanced cert - and then we added on our nitrox cert too. One big perk of this boat is the small diving groups - my husband and I were just with Pit. The food was sooooo good and I loved the warm towel and drink after every dive. Boots and Sam ran a safe and organized boat, and then were fun to chat with after dinner. We loved our trip and highly recommend the Blue Dolphin!

What a wonderful trip!
Our dive guide Pit is very very friendly and passionate, we are lucky to have her as our guide. The marine lives here in Similan and Surin National Park are amazing! Never ever had seen so many fishes which make the visibility very limited (but I like it)! Food and drinks are tasty and plenty, crews are always happy to aid you on whatever you need.

An absolute must-visit
The trip was fantastic and outdid our expectations. Steve, Ciarra and Will were very hospitable and also very knowledgeable about the area, and were able to show us some amazing marine life. Ciarra was our dive guide and she’s so lovely to dive with. The food was delicious and we were extremely well fed on this trip - with breakfast, lunch, dinner and a snack in-between (all delicious btw), you couldn’t go hungry at any time. We will definitely be visiting again and diving with the team at Blue Dolphin - highly recommended!
