Bucket list trip!

This is trully a bucket list experince for experienced divers. The diving can be challenging in terms of depths and currents. The rewards in terms of sharks and other marine life are awe inspiring. The island itself is another adventure, drenched in rain and covered with birds. The vessle is older but very seaworthy. Accomodations are a bit cramped. The food and company onboard is great. Also free beer and wine AFTER diving. The crew are experienced dive guides with careful and consistent attantion to diver safety.

Incredible experience only matched by the incredible staff on board.

Seeing the hammerheads up close, a whale shark and swimming with the dolphins. The vibe was super positive with the staff and other guests on the trip so not a bad way to spend 10 days stuck on a boat together.

Top notch in every aspect!

The diving was incredible- hammers on every dive (and whitetips, blacktips, Galapagos, silvertips), lots of rays, schools of jacks/snapper/grunts, frog fish, flounder, lobster, and hundreds of other types of fish. Swimming under waterfalls our playing soccer on the beach between dives...all in paradise. I can't wait to go back!

I have been on a number of liveaboards and the Okeanos/Cocos was #1 in both the diving and the staff. We were seriously well taken care of- friendly staff, consistently excellent food, efficiently managed dives,, and oh my, what dives! Healthy reefs teaming with life on all scales, all in the midst spectacularly beautiful location!

Great crew, great food, beautiful dives

Every dive was a shark dive, and we got to see a variety of these majestic creatures every day. We also took shore trips to bathe in rivers and waterfalls. Every meal was nutritious and gourmet, with just the sorts of food needed to sustain diving.

Once in a life time experience.

Did three 100 foot dives a day for 7 days with my wife and two sons. Saw numerous sharks and other species in a natural environment that appears to be not to harmed by man. The crew could not have been any nicer or accommodating. They take their jobs seriously and are good stewards for the island.

Pretty good, but not as good as expected

Giant mantas, getting pretty close to several sharks and to dolphins. The desserts were great, and the food was pretty good. The service was good and the divemasters were pretty good, but we saw way fewer sharks than expected. On some dives we didn't really see any (besides white tips), and on many dives we were lucky to see one or two. Still, if it weren't for the high expectations, I would say it was great.

Great diving and great service!

The diving is just great! We made 21 dives, hammerheads on all of them. Many other type of sharks and much more fish life than I expected. The crew was fantastic. They were very helpful and friendly! And the food was excellent, probably the best chef in all Costa Rica!
