Among Cocos Island’s many attribute is a startling degree of biodiversity. This Island’s world-renowned waters explode with life, including innumerable white tip reef sharks, schooling hammerhead sharksdolphinsmantas and marbled raysgiant moray eelssailfish, and of course the occasional whale shark. Other common encounters are large schools of jacks and tunasilky sharkssilvertip sharksmarlinCreole fishgreen 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. Here are found some 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.


Beneath the waterfalls and in the rivers, are freshwater fish that mystify scientists by their very existence. Because of its remote location and abundance of freshwater, Cocos has, throughout history, been a favourite re-supply station for pirates, whalers and sailors.

Many kinds of dives on offer, ranging from vertical walls, drifts, pinnacles, as well as incredible marine life, including hammerhead sharks, sailfish, and whale sharks.


Spent diving the pinnacles around the perimeter of Cocos Island. Divers usually average three dives per day at depths of 60-100ft (18-30m) or more. This, of course, is what the whole trip is about.

The following day, generally between 8 AM and 1 PM we pick up from certain hotels and transfer everybody by bus to Puntarenas where you will board the vessel. The drive takes about 2 1/2 hours, and gives you a chance to view the lush forest and rich farmland of the region.


Due to occasional low tides our boats may need to depart from the pier earlier in the day. Should this occur, you will be transferred by skiff to the vessel. When all passengers have arrived on board, the vessel will take a 32-36 hour cruise out to Cocos Island.


Day 2

While you are here in Costa Rica it is certainly worth the extra time to visit other aspects of the country that truly make it a natural wonderland.

Your first Cocos dive and one of our favourites is Manuelita Island inside, which faces the calm waters of Chatham Bay. This well-protected site receives little current or swells. These calm conditions support a beautiful shallow garden at depths ranging from 20 to 70 feet. It is a macro-photographers heaven. 


Countless fish, eels, lobsters and many other critters are residents of the hard coral reef and the adjacent sand slope. Large fish are frequent visitors to this site, including hammerheads, black tip sharks, white tip sharks and numerous marble rays. 


Marine life:

Whitetips, marble rays, manta rays, eagle rays, turtles, black tips, garden eels and the most recent addition: Tigers Sharks!

Manuelita Outside

The southernmost part of the island, Dos Amigos Pequeno, is not always accessible during the rainy season due to the rough surge around this exposed site.

Bajo Dos Amigos

Bajo Dos Amigos is a seamount shaped like a king's crown; this is the only place where black coral colonies can be watched at safe depths, between 100 and 130 feet. Definitely not an easy place to dive, due to the strong currents normally present on this site, we will only visit here during the dry season.

Shark Fin Rock

From the surface, this pyramidal rock looks exactly like its name, shark fin. This beautiful site hosts a huge school of thousands of bigeye jacks and is the home of an active colony of friendly marble rays. Because of the heavy surge often present on the spot, Shark Fin can only be safely dived between 40 and 120 ft.


Marine life:

Marble rays, white tips, mobula rays, eagle rays, dolphins

Bait Ball

Dive map of Cocos Island


0 - 20 ft. / 0 - 6 m.


This phenomenon occurs when the little bait fish, upon being hunted, seek protection by forming a furiously spinning silvery ball. This is an attempt of a small species to intimidate and confuse a predator. In a bait ball you can find different bait fish and different hunters. Sometimes the bait fish will be trapped between the surface and the hunters below. This is when the boobies and frigate birds will join the feast. These special events can happen anywhere and at anytime.


Marine life:

Green jacks, yellowtail grunts, rainbow runner, silky sharks, blacktip sharks, dolphins and tunas


Submerged Rock
