Outstanding dive trip

Even with El Niño negatively affecting the dive environment, we still encountered hammerheads, Galapagos and Black Tip sharks. Not to mention the abundance of fish, reef sharks, and rays. The crew went out of their way to make our trip as comfortable, safe, and successful as possible.

"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.

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

Unbelievable dives, hospitality/service, dive guide knowledge and professionalism

The best trip for me on planet earth.

Schools of hammerheads; all the different rays: manta, mobula, bat and marble; jack school; a trip in the submersible to 1000’ but also, all of the other fish, big and small…I loved them all.

Incredible diving, fantastic crew and fellow divers.
