Cocos Island of the Sharks

Cocos Island is an oasis for marine animals off the west coast of Costa Rica and is spoken of in hushed tones of wonder by divers around the world. It is famous for being one of the hottest shark diving destinations in the world. The schooling scalloped hammerheads are legendary. In recent years, tiger sharks have become more common. Whitetip reef sharks and silkies, our favourite "puppies of the sea" are common. Other species regularly encountered include galapagos, blacktop, silvertip, as well as many species of rays, especially around the cleaning stations. It's easy to get lost in mesmerizing giant schools of big eyed jacks and mutton snapper.

To Carlos who showed us one of his dive sites, THANK YOU for a special dive with some silver tip sharks, and some mantas! That dive is a big highlight for me, seeing a baby silver tip shark! Also spotting Tiger Sharks with Ima was special, and a memory that will stay with me for a long time!

Ima, Carlos, Beto and Esteban (Pato) were incredible Dive Masters to have on this trip! Carlos and Beto truly know Cocos, and having Ima and Esteban there to help guide was perfect!! We felt taken care of the entire time by the entire crew. Osa always had hot chocolate waiting for us, Ramon is was always there to help us getting out of the water, and Luis cooked the most incredible food (I wish I had the salsa recipes). Overall, this was an incredible trip, and this crew made it all the more special for all of us!

Just a big thank you to the crew - we all had a great trip.

The whole crew was great as they have been on our last Nautilus trip. Beto is very helpful both as a captain and dive guide - we love coming on trips when he is the captain. Ima was also a great guide for us - high energy, helpful underwater, fun, and safe. The rest of the crew was great including Osa, Pato, Ramon, Carlos, Diego, and Luis.

Absolutely! From the moment Ima met us at the Hotel I just knew this was going to be an incredible trip with a Top Tier crew! Huge shout out to Ima for his stellar personality, perfect dive-breifings, and overall hospitality in general.
Next up, CARLOS! Ah! What an amazing Guide! There is no doubt in my mind Carlos LOVES what he does; and he's truly amazing at it! Every conversation I had with him he was so kind, friendly, and knowledgeable! Our trip to the island was a true showcase of his passion for his work - one of the best parts was seeing him interact with the Park Rangers and Staff who either have known him for many, many years, or could just tell his soul is kind and deserving of their compassion. Some people are personable, others are wise, and some are like Carlos the best combination of all attributes.
I cannot go on without mentioning Ramon! While I didn't have the opportunity to spend a tremendous amount of time with Ramon, any time he was around the vibe was 'on-point'! Another kind soul who made our experience feel like we were right at home!
I want to mention every single one of the Crew, as they were all incredible - I really feel like this group of individuals are a true family!

Simply . . . Thank you!

Honestly, each and every crew member made it their personal mission to treat me, my family, and all of the other guests like THEIR OWN family. This was NOT something paid for . . . but sincerely offered.

As in Coco's Islands is raining all the time, I recomend consider the option of adding more covered open areas, that would allow the guests to stay in the decks and not only in the living during resting time in between dives.
Staff standout
Xavi was always ready to help us not only during dives but also at all times, we really appreciate that. Jose, was also always willing to help and make us feel comfortable during the whole trip.
