Great Liveaboard for an amazing place
Cocos is the best diving I have ever done. Sharks (a lot of) on every dive. The staff, food, activities and just everything proposed lives up to the high expectations that is Diving Cocos Island. Will go back ASAP!!!

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!

Unbelievable trip best staff I've ever experienced diving both live aboard and land based.
Where would one begin? My first whale shark in 30 years of diving, or maybe the dive where simultaneously we had a huge Manta ray two hammer heads three Galapagos Sharks a Large Tiger shark and a two hundred pound Tuna rolls through. Every meal was a highlight as was the entire staff perfect organization. Without question the best live aboard ive done. That starts at the top nice reflection on the Captain.

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.

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.

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.

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!

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.
