Unforgettable Liveaboard experience with awesome dive guides, crew and food.
Blue Dolphin was an excellent liveaboard that we would recommend to anyone else wishing to dive the Similan and Surin Islands. The Dive guides and crew were excellent. Safety was high on the list of priorities. Food was absolutely amazing and the cooks went out of their way to cater to anyone who was vegetarian. Richlieu Rock was unforgettable. We would certainly be happy to dive with them again.

Wonderful experience!
Wonderful experience! Although we weren’t lucky enough to see manta rays or whalesharks, the diving experience with Blue Dolphin was truly amazing with great food, service and friendly staff. My favorite was definitely Richelieu Rock, you will certainly enjoy large schools of fish swimming around you and other rich marine life there.

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!

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!
