    Wahnsinnstauchplätze und riesige Galapagoshaie Cocos Exploration, Costa Rica in March

    The absolut highlihts of this trip were the schools of hummerheads, the very closed big fat galapagos sharks and fantastic guests. The hospitality of the crew was amazing. The best liveaboard food we ever had on a liveaboard! Additional a very good organisation. Coco`s is not the cheapest place to dive but one of the best of value for money! I strongly recommend it!.

    As good as indonesia on some dive sites Cano Island Exploration, Costa Rica in January

    some sites had several schools of different kinds of fish, as well as sharks and turtles, all in one dive. I like to watch schools of fish. I have been to Indonesia on many dive vacations and Cano Island is as good as Indonesia for schooling fish on some dive sites.

    Hammerheads galore Cocos Exploration, Costa Rica in December

    This was only my third liveaboard so I don't have a lot to compare this to. My first two liveaboards were so awesome, so this one was a bit disappointing. The standard cabins were very small. Only two dive masters for 19 divers. We did 23 dives and the diving was quite good. I just didn't feel the love from the crew like I did on my first two liveaboards. I didn't sense much passion for diving or hospitality. There are not a lot of options for diving in Cocos so maybe there wasn't a lot of motivation from the crew to make it an extraordinary experience for us.

    One of those bucketlist destinations...Has to be done at least once! Cocos Exploration, Costa Rica in December

    Diving against the classic 'wall of hammerheads' on Dirty Rock and getting up close with my first two tiger sharks. Everything is also super sized here, the sharks, the enormous (!) schools of fish, the multiple rays (we had two surprise mantas our week). Note that the boats travelling to Cocos are more simple than most of the luxury liveaboards you get in e.g. the Red Sea and Maldives, but hey, you have everything you need and who cares when diving this great!

    Perfect sport for shark lovers Cocos Exploration, Costa Rica in August

    Cocos Island is a fantastic option for shark lovers due to the variety you can find at each dive. It is a long trip from Costa Rica but completely worth it. The crew did a great job to make sure we all felt comfortable. Special mention to the chef and his assistant, who amazed us every day with fantastic dinners.

    Amazing!!! Cocos Exploration, Costa Rica in May

    The highlight of the trip must have been being face to face to a tiger shark right away on check dive...and it only went up from there!

    Big animal life not as abundant as expected/anticipated Cocos Exploration, Costa Rica in December

    Overall, boat, food and crew were great. White tip sharks abundant, other shark life averaged 1 or 2 per dive, with Galapagos, black tip, hammerhead and tiger sharks. Limited sites around Cocos. Crossings were better than expected. Water was very warm, 3mm wetsuit fine, but probably why the bigger life was limited, El Niño conditions?

    An unforgettable trip Cocos Exploration, Costa Rica in August

    The dives were diversified but their quality consistent and most of them were as fun as they were extraordinary. My cabin (the Master cabin) was just perfect and I loved the exquisite attentions on some evenings (chocolate on the pillow etc). But I found the sandard cabins really very small, especially considering the price (that's the reason of the 4 stars "only"). I would like to point out the professionalism, efficiency and friendliness of all crew members, from the cleaning man to the captain. They are all précieuse and really made this trip all the more enjoyable and all the more difficult to leave at the end. The food was also absolutely fantastic and the chefs accomodated me with delicious dishes accordingly to my vegetarian diet. Even though the boat is obviously not brand new, I found it beautiful and well maintained and enjoyed every moment on what felt like a floating home away from home. If the trip was not so expensive (one of the only flaws I can se), I would definitely do it again next year, and maybe the next, and over and over again.
