I am an experienced liveaboard diver. I have been diving on much more expensive liveaboard boats. However I have never been treated as well as I was treated on the blur Dolphin. The staff literally bent over backwards to accommodate all my needs, both dietary and physical. The next time I go diving in Thailand it will be with the blue Dolphin without a 2nd thought.

The dives and the food - 4 nitrox dives and 3 whole meals (plus a sizable snack) each day - pretty amazing!

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.

Die Tauchführer und die einheimische Botd-Crew waren ein sehr gut harmonierendes Team auf einem sehr schönen und sauberen Schiff auf einer sehr kurzweiligen Tauchsafari.

Phantastic 4 days

We booked the 4 nights tours around the Similan islands, and our time on the Blue Dolphin was just perfect! The boat is newly refurbished and spacious, catering to smaller groups and taking only 4 divers per guide. Our en-suite cabin was big enough for our suitcases, with a hot shower and a good AC. The instructors Alex and Brie were wonderful, taking care of everything and making us feel safe and well informed. The crew was amazing, always wearing a big smile and feeling us more than welcome, and the food was plentiful and always just great - and we were fed 5 times a day ;-) the dives were amazing, too, plenty of fish and marine life, different sites for all levels. The equipment was in great shape, too - everything was really phantastic, we enjoyed our 4 days thoroughly and can absolutely recommend the Blue Dolphin.
