The crew was super friendly and helpful. Everyday fresh and super delicious food. The dive sites were selected by the national park, therefore it can happen that you dive several times at the same site but no dive is like another. The dive guides were experienced and taking care of the divers very well.

Diving wirh the sharks was one of the most incredible and rewarding experiences of my life.
Diving with the hammerheads, white tips, and rays. Being in the ocean experiencing and being part of the ecosystem. And feeling safe thanks to Warren and the other dive masters. Also seeing the dolphins surrounding the panga on one of the dives. The food and service was excellent. Muchas Gracias!

Fantastic trip to Coco's island
The raw wildlife and nature on Coco's island were stunning. Every night there was a beautiful sunset. Also the service of the staff was incredible! Every time we got out of the water they distributed fresh fruits and towels. During our first dive of the day the staff always checked our rooms and cleaned the toilets. I also liked that they made a video of the whole trip which we could purchase additionally. This was our first liveaboard and we enjoyed it so much! Thank you guys!

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.

World-class diving, friendly and professional staff
The two favourite dive sites - Dirty Rock and Punta María - and the night dives has offered me a magic that i will never forget. The island is intact, true nature, the sky is full of shiny stars. On the top of this the staff is really professional and ready to serve the guest with the highest possibilities with a big smile. Lifelong experience. Thank you.

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!
