Dive Dive Dive!
Dive was great. I saw what I wanted to see, including a whale shark. Crew was very helpful. Dive staff were very professhional. Maybe because it was full moon, I felt like the view of Cocos island was very special (and beautiful!) The only thing I can complain is engine nosie is too loud.

The diving was great, and this isolated island is fascinating. We were the only boat on Cocos ! The crew is really doing his best to make the trip unforgettable

Excellent crew, food, comfort
Hammerheads, Carlos, our Cruise Director, has the patience of a saint. He fixed my faulty equipment onboard the panga twice, immediately before the dives so I did not miss any dives. Deeply appreciated his cool, calm and humourous attitude.

All around amazing Liveaboard
Mind-blowing dives with schooling sharks and fish, a world-class crew - all master of service within their disciplines, personalized care for each of the guests, a clean and comfortable boat with so many little touches (e.g. laundry, beer, nightly events), all with the backdrop of a beautiful and untouched paradise island

"Pura Vida!" The 'must dive' Cocos experience.
Swimming with a wall of hammerhead sharks, drifting with thousands of Jack's, and diving with knowledgeable experts and good diving companions. These memories will stay with me for ever. It did rain for most of the trip, but that did not spoil it for me, even with reduced visibility by Cocos standards, it was amazing to a British diver. This is not a trip for the inexperienced. There was some challenging currents and waves, but our trip was in the rainy season. Everything was very efficiently run and all were extremely helpful and friendly. To really seal an excellent trip, my clothes were washed, dried and neatly folded just before we returned. Luxury indeed; worth every penny and hopefully I will return to Cocos, on Sea Hunter but in the dry season.

great trip in Cocos
We had really great dives at Cocos, full of hammerheads and other species ! The skiff drivers and dive instructors really try to give you a great experience - short stops on sea after spotting wildlife or even stops to see different places of the islands (waterfalls, etc - stayed on the boat) The boat is very nicely designed with a place for everything. All you need is onboard. The crew was amazing, very helpful, always in a good mood. Food was great too : healthy and different everyday !

Shark Heaven off Cocos
Every dive was very good, but the first dive we saw the Whale Shark. On several of the dives, the Barber fish cleaning stations were so active it was a constant flow of hammerheads.

- The dive panga crew was excellent - Roberto, Juan Manuel and Balin are some of the best we have dove with. Great shark experience; whale shark, lots of hammerheads and white tips, silkies, Galapagos and oceanic blackcaps.
