Extraordinary
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.

magical diving in Cocos island
My reason to go to Cocos island was to see sharks. I saw a lot of them, mainly hammerhead sharks, whittip sharks and some tiger sharks. The hole experience was amazing. Thanks to the chef who prepared delicious food every day.

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!

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!

Less hammerheads, great service
It was January so we didn’t see large schools of hammerheads but we did see plenty of them, and tigers and even mantas and silver tips. Food was excellent and the level of service on the boat and when diving was fantastic. All the staff were great. Dived a variety of sites. I thoroughly enjoyed the experience.
