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.



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 rental of Nitrox computers. 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.
  • Rental Equipment Onboard
  • You can rent a complete line of ScubaPro dive gear: BCD, regulator, wetsuit, mask, fins, snorkel, and Aladin Nitrox dive computers. There is a limited supply of 15 Liter steel tanks. If you would like to rent one, make sure to reserve it well ahead of time.



  • Day 1 - Upon arrival in San Jose, Costa Rica, you will need to take a taxi or have us prearrange land transportation from the airport to your hotel. There are plenty of taxis available at the airport, even big cars for those of you who carry a lot of gear. The land transportation vehicles are spacious shuttle busses. The same evening, the SEA HUNTER representative will fax you to confirm your pick up time, the next day. Evening at your leisure.
  • Day 2 - You will be picked up at your hotel and transferred by bus to Puntarenas, a seaport village where the SEA HUNTER boards its passengers. That afternoon, you will begin the cruise to Cocos Island.
  • Day 3 - All day of travel. There will be ample time to arrange dive and camera gear. The cruise gives you an opportunity to get acquainted with the other divers.
  • Days 4 to 9 - Spent diving the pinnacles around the perimeter of Cocos Island. Divers usually average three dives per day at depths of 60-100' or more for up to 21 dives on a trip. Water temperature of approximately 78-82F (27-30C).
  • Day 10 - Make the last 3 dives before the cruise back to Costa Rica and reality!
  • Day 11 - All day to discuss the diving and to compare your adventures!
  • Day 12 - Arrival in Puntarenas. Immediately after breakfast you will be transported back to San Jose. Upon arrival in San Jose we recommend that you spend an additional hotel night prior to departing the country.

Reviews (1)


A very comfortable ship with a top notch staff who go above & beyond to please. Excellent food and oh, by the way the diving is fantastic, too. Mind blowing in fact. Dive Master Frederico seemed to have a sixth sense as to what we were going to see, and when and where. We are true "Cocoholics" who will return via the Sea Hunter for a third visit in 2015.

SHIP: The ship is comfortable because it is big enough to not be crowded. There is enough room in the dining room for everyone at once with room to spare. There are nice lounging places inside and outside for between dives and the state rooms all have private bathrooms.

FOOD: There is good variety and lots of it. No extra charges for pop or juice. Even all the beer you could drink was included. I have a nasty allergy to garlic and the chef made personally sure that I didn't get any.
The dive masters were very professional. They quickly picked up on who might need a little extra. They obviously loved diving and passed their enthusiasm on to their guests, which is not always easy when one does it every day.

MARINE LIFE: We saw white and black tip sharks, silky sharks, galapagos sharks, tiger sharks, whale sharks but mainly hammerhead sharks. Also, dog tooth tuna which scare the sharks off and rivers of jacks and cleaner Wrasse. Also dolphins, several varieties of rays, octopus, and even frogfish and batfish. Even saw a couple of humpback whales. Not sure what else we could ask for. The shark sightings are not rare, they are the norm. Often, there are so many one can't see through them.
