      What To Expect On a Cocos Islands Liveaboard

      Cocos Islands liveaboards will take you some 550 kilometres from the Costa Rican Pacific coast, where divers will find nutrient rich waters filled with diverse marine life of all shapes and sizes, guaranteed to wow even the most experienced of underwater addicts. The Cocos Islands of Costa Rica represent some of the best diving opportunities in Central America, and considering this region includes the likes of Belize, Mexico and Honduras, that is certainly saying something. The combination of remoteness and protection afforded to it by the Costa Rican Government (it's been a marine reserve for nearly 20 years), means that the sites at Cocos Island are largely undisturbed which has allowed the ecosystem to thrive. All the usual tropical species are to be found here, along with large pelagics - but the main draw for many visitors are the sheer numbers of sharks, particularly Hammerheads, that can be seen year round. The only feasible way to get here is on a liveaboard dive trip, which tend to last for at least 10 days giving ample time to explore the stunning underwater landscape that exists in this unspoilt spot of the Pacific.

      Cocos Islands Underwater

      Having travelled for nearly 2 days on board, you'll be itching to get in the water to see what all the fuss is about! Thankfully, there's no shortage of life in each of the individual sites at Cocos. The area is deservedly on many diver's bucket dive trip lists due to the large groups of Hammerhead Sharks that are consistently seen in many sites - numbers can regularly top 100! There's plenty of other shark species to be found here as well, including Silkys, Blacktips, Whitetips, and the infamous Tiger Shark.

      Manta and Eagle Rays are always seen, gliding effortlessly through the blue, as majestic as they are beautiful, offering some wonderful photo opportunities. Schools of fish such as Jacks can be viewed in vast numbers, and because the visibility commonly reaches 30 metres you can be sure that none of this action will go unnoticed.

      Dive Sites of Cocos Islands

      With over 20 dive sites to explore, it's easy to see why a live aboard is the best and only way to dive Cocos Island. With each dive safari lasting at least 10 days, the crew will ensure you can undertake a few dives per day in order to include each spot in your itinerary.

      Bajo Alcyone is widely recognised as one of the best places on the planet to dive with Hammerhead Sharks. Their unique body shape is this animal's distinguishing feature, and seeing them as part of groups in excess of 100 is a truly staggering sight. Viewing these graceful creatures circling above you makes for one of the most iconic photographs of any Costa Rican dive trip. Other sites with many resident Hammerheads include Dirty Rock, and Manuelita Deep

      Manuelita Garden is often the first site that liveaboards stop at, giving easy and gentle conditions to allow divers to get used to their equipment and tune up their skills. The coral garden here is one of the finest in Costa Rica. The giant swim through and huge natural arch at Dos Amigos Grande provide an interesting and fun element to the diving here as well.

      Top Tips For Divers

      Diving at the Cocos Islands used to be limited to experienced and daring divers due to the depth and strong currents at some of the sites, however liveaboard dive cruises lasting for many days have allowed exploration of a range of sites that suit many experience levels. Having said that, often operators will require a minimum of 30 logged dives and an Advanced Open Water qualification. As such, it's important to bring your log book and certification.

      Divers are welcome to bring their own equipment, but generally it's available to rent onboard, although this should be checked first.

      ATMs are found fairly easily on the mainland, where most major credit cards are widely accepted. Currency is the Costa Rican Colon. You'll get on fine speaking English as it's commonly spoken especially within the tourism sector, although Spanish is the national language.

      Getting to the Cocos Islands

      As we've mentioned, the Cocos Islands are over 500 kilometres from the mainland. You'll need to get onboard a liveaboard boat to get there, and the common departure point is the port of Punterenas, around a 90 minute drive from the capital San Jose. Commonly liveaboard operators will include a hotel night in San Jose and then transfer to the vessel as part of the tour. Others can arrange this for you as an extra. Either way, please check with your operator.

      San Jose International Airport has regular flights to and from North America; if you are coming from outside the Americas then it's likely you'll transfer through the US.

      Fabulous, second to none. Schooling hammerheads, tiger sharks and white tips galore. Vis was better and currents more manageable than expected - even the crossing could have been worse.

      Absolutely met my expectations. Lots of "big stuff", meaning most kind of sharks, huge hammerhead schools, big tiger sharks, galapagos shark, white and black tips, etc. Not too cold water temperature, except from some funny-cold-as-hell thermoclines :) Strong current at some dive sites, so
