Cocos Island is a remote oceanic island in Costa Rica considered one of the planet’s great marine sanctuaries. Surrounded by nutrient-rich waters and far from any inhabited area, it has become an exceptional refuge for large pelagic species and a worldwide benchmark for adventure diving.
Its terrestrial and marine environment is protected as a National Park, which has preserved a virtually pristine ecosystem where wildlife remains the true protagonist.
Due to its exceptional ecological and natural value, Cocos Island was declared a UNESCO World Heritage Site and today is considered one of the most spectacular and exclusive diving destinations on the planet—a true dream for any ocean enthusiast.
*By making a booking, you accept our terms and conditions.
Cocos Island is located in the middle of the Eastern Pacific Ocean, more than 500 kilometers off the coast of Costa Rica. Its geographical isolation makes it one of the most remote and best-preserved destinations in the Americas.
Far from cities, ports, and permanent human activity, the island rises as a tropical rainforest oasis surrounded by deep waters that attract a massive concentration of marine life. This privileged location is precisely one of the reasons why it offers some of the most impressive underwater encounters on the planet.
The Okeanos Aggressor II is a comfortable liveaboard vessel designed for year-round diving expeditions to remote Cocos Island. Accommodating up to 22 guests across 11 cabins with private bathrooms, it offers a comfortable environment to relax between dives.
Onboard, you will find spacious common areas, a restaurant, bar, sun deck, and spaces to enjoy the cruise and share experiences with fellow divers. The cuisine is one of its highlights, featuring buffet-style breakfasts and lunches, along with dinners prepared daily by the chef.
From Puntarenas, the vessel makes the approximately 36-hour crossing to Cocos Island.
SPECIFICATIONS:
Here, the ultimate protagonist is the ocean. Diving in Cocos Island means immersing yourself in one of the wilding environments on the planet, famous for its massive aggregations of hammerhead sharks, whitetip reef sharks, mantas, huge schools of fish, and the potential for encounters with other pelagic species.
The dives take place around seamounts, pinnacles, and cleaning stations where the action can happen at any moment. The currents and nutrient-rich waters make every single descent an intense and unique experience, suited for those seeking true underwater adrenaline.
However, the adventure begins long before the first dive. The ocean crossing to the island, the vastness of the Pacific, the mist-covered rainforests, and the waterfalls cascading directly into the sea are all part of a unique expedition that very few places in the world can deliver.
Far more than just a diving trip, Cocos Island is an exploration experience in one of the last great marine sanctuaries on Earth.
Did you know… Cocos Island is the only exposed landmass of a vast underwater volcanic range known as the Cocos Ridge, a true oasis of life in the middle of the Pacific Ocean?
Cocos Island is not a conventional destination. It is a trip designed for divers who dream of exploring one of the most remote and legendary places on the planet.
It is intended for those who already have experience, feel comfortable diving in currents, and are looking for encounters with large pelagics in a completely wild environment. You don’t come here looking for colorful reefs or relaxed dives: you come to live an authentic ocean expedition.
If you have ever imagined descending surrounded by schools of hammerhead sharks, taking in the sheer vastness of the Pacific in its purest state, and being part of an adventure that few divers ever get to experience, this trip is for you.
It is not simply a diving trip. It is an expedition to one of the last great marine sanctuaries in the world. And for many, the dream trip of a lifetime.
Cocos Island is one of the most legendary diving destinations on the planet and the main reason why thousands of divers dream of traveling to this remote corner of the Pacific.
Underwater, some of the most spectacular encounters the ocean has to offer await you. Dives at iconic spots like Alcyone, Manuelita, Dos Amigos, or Dirty Rock provide the opportunity to witness massive schools of hammerhead sharks, manta rays, whitetip reef sharks, huge shoals of fish, and many other pelagic species in a completely wild environment.
However, the experience goes far beyond diving. The journey to the island itself is part of the adventure: navigating the Pacific, admiring its breathtaking waterfalls, and hiking the authorized trails of this National Park turn the trip into a true expedition.
Additionally, many travelers take advantage of their time in Costa Rica to discover some of the country’s natural treasures, such as its tropical rainforests, volcanoes, wild beaches, and national parks, adding even more value to an already unforgettable experience.
