Cocos Island Overview

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."

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.

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 fresh water, Cocos has, throughout history, been a favorite re-supply station for pirates, whalers and sailors.

Early visitors left pigs on the island as a self-perpetuating source of fresh meat. To this day feral pigs and deer abound, much to the detriment of the island’s indigenous ground-nesting birds. These animals, introduced by man, are also responsible for hastening soil erosion with their digging, which undermines and degrades the native vegetation.

If you have extra time before or after your liveaboard trip to Cocos, be sure to consider an extension on the mainland of Costa Rica.

Dive Trip Information

  • Dive Experience for Cocos Island
  • Cocos Island presents the same diving challenges as any other Pacific, Indian or Red Sea diving location. Cocos, however, is not recommended for inexperienced divers because it is an open ocean destination that requires advanced open water diving skills.
  • Please note, the minimum required level of certification to dive at Cocos is Open Water and we strongly recommend having at least the Specialties of Deep & Night Diver. We also recommend having a minimum of 25 hours of diving experience.
  • Most dives are at depths deeper than 60 feet / 18 meters. At Cocos, currents and visibility can be entirely different in just a few hours. 
  • Please note, the dive guide will always be the final authority as to whether a passenger can do any specific dive.
  • Dive Conditions
  • Most of the action is at 60-90 feet /18-27 meters, and most dives are between 60-130 feet / 18-40 meters. The safety limit is set at 130 feet / 40 meters and a dive computer is necessary. Visibility averages 60-100ft/18-30m.
  • Water Temperature
  • Average temperature is 79 F to 84 F (26 C to 29 C), although it can be a few degrees lower under the occasional thermocline.
  • Certification
  • All divers must bring proof of certification by a national certifying agency. The certification must allow the diver to dive to the recreational dive limit of 130 feet (40 meters). 
  • The Dive Master will request to see your certification before you are allowed to dive. If you are certified for Nitrox and rebreathers as well, then remember to also bring those certifications.
  • Nitrox
  • To increase safety and bottom time while maintaining safe non-decompression dives the use of Nitrox is recommended. The vessel offers full onboard TDI training in Nitrox, with Nitrox computers rental. Nitrox fills are free for Nitrox certified divers.
  • The Crossings
  • When all passengers are boarded, the vessel will take 32-36 hours to reach Cocos Island. Crossings are normally calm, but to prevent motion sickness we advise you to take the necessary precautions. At the conclusion of your trip, we will return to Puntarenas where a bus will be waiting to return you to your San Jose hotel.
  • Gear to Bring With You
  • You will need the following gear: 3-5 mm (1/8" to 3/16") wetsuit, mask, fins, snorkel, regulator with visible pressure gauge, a mandatory dive computer, buoyancy compensator, depth gauge, dive gloves, weight belt (without weights), dive light, and dive watch. It is recommended that you mark each piece of gear with waterproof paint or tape. We suggest you put all or most of the above items in a carry-on bag. There is ample storage space for your diving equipment, including your own personal locker.
  • Equipment Provided Onboard
  • We provide you with weights for your weight belt: 2, 3, 4, and 6 lbs. (1, 1.5, 2 and 3 kilos). We also provide you with air or Nitrox tanks -- 80 cubic ft. aluminum (12 liters). Please note, the tanks are standard yoke (INT), not DIN. Please notify in advance if you need an adaptor.

The Argo is incredibly well run by the Undersea Hunter Group. I have been to Cocos 3 times on the Argo. The dive operation, facilities and boat are very top quality!

Of course the diving at Cocos is spectacular if you like sharks. Large schools of hammerheads, hammerheads coming in close to cleaning stations, Galapagos sharks, tiger sharks, huge schools of jacks, snapper, and lovely swim-throughs are part of the diving. For a change of pace, too, there are a couple of shallower dives that include frogfish, stonefish, boxfish and other photogenic species besides sharks. Large eels, octopi and a wide array of life can be found here. The Galapagos, Cocos and Socorro are some of my favorite destinations.

The dive area and camera tables are laid out perfectly. It makes sense that one of the owners was a captain in the Israeli Navy. He has an engineer's mind and this operation is designed and run tightly as you would expect of an engineer or a navy captain.

The food is great and customized for those with food allergies. The cappuccino machine delivers tasty caffeine with or without steamed milk 24/7.

The guides are personable are knowledgeable. Very explicit on diving methodologies, profiles and dive briefings.

The Argo is the best liveaboard experience I have enjoyed. I am a past dive instructor with over 1600 dives around the world.

Argo was super comfortable, the rooms had plenty of storage space and enough room on top to have camera equipment, chargers etc.Bathroom was great, good hot shower whenever you wanted. Rooms were cleaned every morning.
There were 4 Skiffs and the deep sea submersible on board and still plenty of room to relax in between dives. The area for camera equipment is great and each diver has their own gear bin with hangers for suits, BCDs etc on top. Showers on deck both hot and cold water for after diving, plenty of yummy food in-between dives - we definitely never went hungry!
The food was AMAZING 5 Star all the way and the BEST thing about this entire liveaboard was the crew! So great, we had such a laugh with them and they helped out going over and above what was required!
Diving - guess I should talk about the diving - Awesome! I came for sharks and boy did I get them :-) My stand out memory is of swimming out into the blue to suddenly be in the centre of the school of hammerheads! Galapagos shark throughout a night dive and quite a few encounters with Tiger Sharks. I could go on! Best Dive trip I have done, I will defiantly be going back and would highly recommend!

It was a total magic carpet ride! I loved it all. Undersea Hunter was great and the crew and dive masters were professional, and fun too. I had a spacious room with twin beds on either side. There were some fumes lingering below deck there but all was clean and well maintained. If that's the best I definitely want to stay that way on future trips. I guess conditions and sea life were considered not that good compared to what they can be, but it blew everything else I've seen out of the water. Admittedly that's not much and I've never done a live aboard before. It was pretty rough and I was seasick a lot but still had the time of my life. So I lost a few pounds; bonus. The skiffs were easy to dive from even in 2 meter seas, and the dive operation was the best organized I've seen. The island was beyond gorgeous with lush water falls and formations, and booby birds galore. Every ride to and from a dive site was a feast for the eyes. I wanted to see sharks and now I've seen like a thousand of them. There were walls of hundreds of schooling hammerheads, white tip reef sharks everywhere day and night, and Galapagos sharks cruising through channels and cleaning stations every day. On a night dive I jumped in first to wait for the rest of the team at Manuelita Coral Garden, looked down at some eels, lobster, cucumbers, and white tips sharks building into their feeding frenzy, and then something made me look left. A refrigerator-sized animal was cruising directly toward me. I was so happy to be about to see something big…tiger shark! I lit it up and it made a slow half circle and cruised effortlessly into the dark. Soon after, the dive master signaled with a strobe to rejoin the team, which I had somehow become separated from.

There were huge tuna and black jack, acres of schooling fish, and marble rays. I sprang for the Deep See 300 meter dive, as did just about everyone. It was pitch black and everything moved in slow motion down there. It wasn't a non stop adrenaline rush but we saw some really neat stone fish, grouper, glowing gelatinous things, jello nose fish, and other strange things.

The whole experience, the boat, the crew, and the people were awesome. On the crossing home I was completely relaxed and satisfied like never before. I want to go back and do it all again and do everything else too.
