A liveboard diving travel experience few can compare to. Cocos Island has been hailed as the 'Most beautiful island in the world' by Jacques Cousteau. Who are we to doubt him? 10 days in diving paradise is all that is at stake here. A unique underwater travel experience.

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 hammerhead sharks, 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 tip sharks, marlin, Creole fish, green turtles and octopus.

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 with the additional 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. Please note, the dive guide will always be the final authority as to whether a passenger can do any specific dive.

Sample Itinerary - May vary slightly between 10-12 days trips

Arrival Day

You must arrive at least one day prior to the boat departure date. Upon arrival to San José, we can have transportation waiting for you for the cost of $35 or you can take a taxi to your hotel. We can also recommend and arrange accommodations for hotels in San José. Please note that we do not pick up from all San Jose hotels.

The evening before boat departure, an team representative will fax you to confirm your pick up time the next day. The evening is at your leisure. Air transport, airport transfers, hotel nights and meals before and after the cruise are not included in the charter.

Day 1

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

A travel day. There will be time to arrange dive and camera gear as well as enjoy the Pacific and the sunshine. Also, the group of incredibly experienced divers provides plenty of stories to pass the time. There are videos and the experience of the Captain and crew to help you get excited for the diving...as if you need them. In addition, you may want to take this time to take one of our diving courses.

Days 3 - 8

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

Day 9

Make the last 3 dives before the cruise back to Costa Rica and reality!

Day 10

All day to discuss the diving and to compare your adventures!

Day 11

Arrival to Puntarenas. Immediately after breakfast you will be transported back to San Jose. We strongly recommend staying one more night on land, before flying out, in case of any unforeseen delays.

  • Ground transportation San Jose - Puntarenas and return
  • 13-day / 12-night or 11-day / 10-night cruise with all meals, including beer
  • Dive-master service
  • Nine or Seven full days of action-packed diving with three to four dives per day (incl. nitrox fills, tanks and weights)


When all passengers are boarded, the vessel will take 32-36 hours to reach Cocos Island (check specific itinerary of Malpelo/Cocos trips for further details on those trips). 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.

Meals & Beverages: The menu aboard offers a delicious combination of American and local cuisine. Meals are varied and well balanced, and we also offer delicious snacks between dives. Food is abundant with plenty of fresh tropical fruit and salads and is served buffet style. Please let us know of any special dietary needs or requests, but try to be lenient, as storage and preparation space is limited.

Soft drinks: Free, Bottle of wine: $15 - $35.

Hard liquor is not available on board but our guests are welcome to bring their own, which should be purchased prior to boarding.

The Dives:

Our goal is to introduce you to varied and exciting dives four times a day. Generally, we have two dives scheduled for the morning, 8 AM and 11 AM. Another dive after lunch, around 2.30 PM and either one more in the late afternoon or a night dive after 6 PM. This schedule can vary depending on events, circumstances and opportunities that may present themselves. Our motto is never turn your back on a magnificent bait-ball, which can appear at almost anytime.

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.

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.

You can rent a complete line of ScubaPro dive gear: BCD, regulator, wetsuit, mask, fins, snorkel, and Aladin Nitrox dive computers.

We have a limited supply of 15 Liter steel tanks, which we can include in your bill (please contact our office for prices). If you would like to rent one, make sure to reserve it well ahead of time.

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 nearest Re-compression Chamber is in the capital of Costa Rica, San Jose, about 36 hours sailing from Cocos, the implications of which are obvious.

Due to the possible increase in the cost of oil, based on events in the past few years, the Undersea Hunter Group reserves the right to charge a US$200.00 per person Fuel Surcharge. This fee will be effective in the event that the diesel price published by Costa Rica's state owned refinery, RECOPE, reaches US$3.80 per gallon (US$1.00 per liter). We will verify the fuel index table 75 days prior to the departure date and if it is necessary to collect a fuel surcharge then we will inform the participants of the trip. The surcharge will be collected onboard.

Smoking is strictly prohibited throughout the boat, each boat has a designated location on the sundeck if one wishes to smoke.

Since it is customary to tip crew members, many people ask us what tip amount is appropriate. This is a very personal decision, as tips are your way of expressing satisfaction. Generally the tip is given to the captain who distributes it equally amongst the crew. Please note that we do not dictate or include tips.

Communication Onboard:

Cocos Island is now equipped with a cellular phone tower, as well as a public phone. When in closer proximity to the Island at certain locations (assuming your cell phone works in Costa Rica), it is possible to use your cellular phone services, but keep in mind, it is still an international call.

After 6 years working in diving research around the world in many different boats and with many different crews I can say that this holiday is the best I have ever been!!

Everything is great: The boat comfortable, clean, with all the elements you can need in your trip!!. The diving equipment is so complete!! Oxygen, helium…all for TECHDIVE, compressed air for cameras…all always ready to use whenever you need it!!. What can I say of all of them… after 20 days working together they made us feel like a family. Alejandro Martin Arjona Granada, Spain

I’ve been for the last sixteen years traveling around the world doing these amazing job together with my company, Pharmamar. I’ve seen a lot, people, countries, religions, cultures, situations, good things, bad things. This holiday has given me the chance to meet some extraordinary people, not only because they are the most professional crew I’ve never work before, they have make me feel like if I was home. Carlos de Eguilior Barcelona, Spain

Having been nearly everywhere in the world worth diving and quite a few that aren’t, Cocos is still the top and crew are still the best. World class! Mark Thurlow, Encinitas, Ca. USA

The experience has been just great. The ship has served as a working base and as a home, resulting in a very comfortable space that has been adapted to all our needs. What has made this stay unforgettable is the crew, their effort, professionalism, experience and their willingness have been excellent.

I would like to thank Captain Rafa for his welcoming manner and the beautiful journey that we all enjoyed, Denis for his speed to fix any small incident that may occur on the boat, Pepe, for his joy, his skills and for sharing his experiences with us, Bryan for his experience, his collaboration at all times and his beautiful video and photos, Jaume, for his permanent smile, his professionalism but above all for his patience, and Don Pedro and Gato, for having us so well fed and cared from the first to the last day.

Thanks for the excellent team of this ship, and for making us feel like at home. Noe Gimeno Barcelona, Spain

As a team we are away on expeditions around the World about seven times a year. This boat and the crew are simply the best of the best. What else can I say? My thanks for making this such a safe, enjoyable and memorable expedition. Ian Thomas Teignmouth, Devon, England

Although we have made so many trips to Cocos already we can't stay away! We really believe it to be the best dive destination in the world. It has the best combination of perfect dive boat, amazing crew and one of the wonders of the world - Cocos island!

We had a wonderful trip. The diving was fantastic. We saw a lot of hammerheads, dolphins and all the other stuff the island has to offer. Dive guides Jim and Bryan guided us perfectly, Pedro’s food was too good, Gato served all the meals with a big smile and there are no words for describing the comfort of “Pepe’s airline” (skiff driver). Thank you so much for a wonderful trip and we hope to come back very soon. Andreas und Gabriele Baldauf Lindenberg, Germany

Our 5th trip to Cocos Island and it is still as wonderful as we remembered. Thanks, crew, for a great time!! Greg & Janet McClelland Lansing, Michigan USA

I been all over the world, diving with many companies, with many divemasters, and many boats….but the Undersea hunter experience exceed them all! First of all the staff (captain, divemasters, pangueros, cocina, etc) where the best ever. Always smiling and making us feel comfortable, safe and have fun. Pius and Jimmy (we could not ask for better DMs). They did everything we asked…never said no for our requests. Definitely the best crew ever! The boat is very comfortable and the pangas are great!!! The dives, one of the best in the world and the food…..Ahhhh…the food…was amazing! Pedro and Pipi are just incredible!

My only suggestion is regarding the national park. Tourism nowadays is the major tool for conservation. That is why tourist should have more access to some areas, like the waterfalls, more hiking trails, more access to the island! To be forbidden to visit a waterfall on the coast is ridiculous. They should allow at least one, and the guides would take us with minimum impact. That’s my only opinion. I definitely will write about this experience in some Brazilian medias and I wish I could come back someday to Cocos Islands. Photos By Cristian

Unforgettable journey ! Very gentle and kind crew. One can feel the vessel is in good condition of care and maintenance. The cuisine is premium thanks to you our chef Pedro. The panga operator Pepe is an outstanding man of the sea and a great companion. Thanks also to Jim, a great diver and guide. Pius coordinate everything in a good and friendly atmosphere. Coco Island is Wonderful! Ribas Moritz Curitiba - Brasil

For the dive sites, it is one of the first class, for sure. Mother nature has blessed this place. With all flora and fauna possible for all wishes.

The crew is willing to help and knows very much the dive conditions. Special thanks here to Pius, who guided the yellow team, which I took part, very professional and remembering us the dive rules, with great sense of humor, we have laughed a lot. And also Jaume, which we can see he is passionate for scuba diving and guiding the diver troops. Food is wonderful and all of them are high educated employees. Congrats to all of you.

Pura Vida tells exactly what I have felt here! Peter Lopes Russeff Sao Paulo, Brasil

The trip was wonderful; the dives were excellent, sharks, rays, morays and lots of life in every dive. The staff was very friendly and made our trip more fantastic, especially during the cross. The food was perfect! Tasty and creative. the dive team was very professional and had the patience to show us every little thing in each dive. The crew made our stay very confortable and happy. Hope to come back to this paradise soon, with the undersea hunter boat. Ana Flavia Pantalena Fortaleza - Ceara - Brasil
