+++ Jurassic Cocos +++

The Island of Sharks

If you like the following, this trip might be for you:

Shark Heaven 🦈

If you say Cocos, you say sharks. And tons of them: whale sharks cruising by, white tip reef sharks, tiger sharks and of course... the schools of hundreds of hammerheads hanging in the cold current. If you are a shark lover, Cocos is a must do.

Thousands of Fish 🌊

Cocos is globally recognised for it shark diversity, but just as spectacular are the huge schools of fish hanging in the blazing current. Schools of jacks, barracuda, trevally and so many more are crowding divesites all around the island.

Protected Island 🌳

Cocos is a green oasis in the middle of the Pacific Ocean. It's status as a marine protected area ensures that there is no fishing around the region, and it's strict regulations ensure you won't see any other dive groups around on any divesite!

Top 5 🏆

The world's best divespots are often up for discussion, but there are some places that transcend personal opinions and are unanimously seen as the diving community as 'world class'. Cocos Island is definitely under that bracket.

Costa Rica 🇨🇷

Costa Rica has incredible natural resources accessible to its visitors: National parks, rain forests, mountains and pristine beaches. We can craft tons of extensions to combine the underwater spectacle with on land treasures.

World Class

Cocos is a world class dive location, and that is a description we refrain from using undeservedly. The topography, marine life and ambience are unique to the region and incomparable to any other place in the world.

La Isla del Coco

"Cocos is a lush, green uninhabited island resting 342 miles off Costa Rica's Pacific coast. Rocky pinnacles surrounding Cocos are beacons for big animals and big action. Schooling hammerheads, countless white-tip sharks, mantas, tuna and even whale sharks call Cocos home."

- Agressor Fleet -

"When I get asked for the best or my favorite dive site in the world I always name Cocos Island. It's not just the magic of this island which makes me want to return. The diversity under water and exclusivity of diving in these waters make it special to me. Also, I simply love Costa Rica itself..."

Intro to Cocos Island

Located in the Eastern Tropical Pacific, 300 miles southwest of Cabo Blanco, Costa Rica, lies the renowned Cocos Island Marine Park. A rugged yet incredibly verdant island, this World Heritage Site is the spectacularly beautiful crown jewel of Costa Rica’s many National Parks. In 1994, after several return visits to the island, Jacques Cousteau pronounced Cocos, “The most beautiful island in the world.”

The island has an irregular coastline, which makes precise estimation of its land area more a matter of opinion than a surveyor’s science, but it is roughly five miles by two miles (8 x 3 kilometers). Cocos Island was formed during a volcanic upheaval about two-and-a-half million years ago and is composed of basaltic rock, labradorite and andesite lava flows. Its landmass is punctuated by four mountain peaks, the highest of which is Cerro Iglesias, at 2,080 feet or 634 meters above the sea. There are only two bays with safe anchorages and sandy beaches: Chatham is located on the northeast side and Wafer Bay is on the northwest. Just off Cocos are a series of smaller basaltic rocks and islets. The largest satellite is Isla Manuelita (formerly Nuez).

Thanks to the breathtaking marine life in its waters, Cocos Island was named one of the ten best scuba diving spots in the world by PADI (Professional Association of Diving Instructors) and a “must do” according to diving experts. Among Cocos Island’s many attributes is a startling degree of biodiversity. This island’s world-renowned waters explode with life including innumerable white tip reef sharks, schooling hammerheads, dolphins, mantas and marbled rays, giant moray eels, sailfish, and of course the occasional whale shark. Other common encounters are large schools of jacks and tuna, silky sharks, silver tips, marlin, Creole fish, green turtles and octopus.

Cocos Island is also home to at least 27 endemic fish species including the exotic rosy-lipped batfish. The terrestrial life at Cocos also exhibits a high number of endemic species. The island is home to 70 of the 235 identified vascular plant species in the world, some 25 species of moss, 27 species of liverwort and 85 species of fungus. There are upwards of 87 bird species, including the famous Cocos Island cuckoo, finch and flycatcher. There are 362 species of insects, of which 64 are endemic. Two native reptiles are found only on the Island.
