Jacques Cousteau has described Cocos Island, a UNESCO World Heritage site, as “the most beautiful in the world”. Large pelagic fish, such as eagle rays, tuna, whales, dolphins and multiple species of sharks call these waters home. One dip below the surface, and it’s easy to see why this destination remains top of every SCUBA divers list.
Designed for both leisure and research, MV Argo is a multi-tasking ship with global reach. SCUBA diving the waters around Cocos Island begin with a 30+ hour crossing from mainland Costa Rica. This 130-foot vessel is more than up for the task. Featuring a DeepSee submersible and remote operating vehicle (ROV), guests are given a rare and unique opportunity to journey to the depths divers could never reach.
MV Argo’s experienced crew of 14 look after your every need. Up to 18 passengers, in 9 spacious, en-suite cabins, with climate control, are pampered from the moment they arrive. No guest will go hungry on this all-inclusive cruise! Fresh 4-star meals are prepared at “the drop of a hat”. Multiple common areas are found along the main and upper deck. The sun deck is the perfect space for relaxation and sunset views.
Arrive at least one day prior to the MV Argo departure date.
8 AM and 1 PM pick up from certain hotels and transfer by bus to Puntarenas to board the MV Argo.
Due to occasional low tides, the boat 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.
Travel Day. This is the time to arrange your gear, get to know your crew and fellow divers and enjoy the open Pacific and sunshine while relaxing on the MV Argo sundeck.
This is what you are here for, diving the Cocos Island! Eat, sleep, dive, repeat. Divers usually average three dives per day at depths of 60-100 feet (18-30 meters) or more.

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 Specialty of Deep 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.
Please check directly with our office if you are bringing a rebreather with you. We can supply you with tanks, scrubber material and any further assistance you need, and can provide you with the costs of these items.
Please note, at this time we are no longer teaching the rebreather course and we do not have any units available to rent. Check for further rebreather information on this website at PRICES & SCHEDULES - Rental Gear

Please note, our tanks are standard yoke (INT), not DIN. Please notify our offices in advance if you need an adaptor.

We have a limited supply of 15 Liter steel tanks. If you would like to rent one, make sure to reserve it well ahead of time.
The menu aboard offers a delicious combination of International 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.

Hard liquor is not available onboard but our guests are welcome to bring their own, which should be purchased prior to boarding.
The vessels maintain constant radio contact in the event of any emergency. Your family and friends can contact our office at telephone: +506-2228-6535. We are happy to let family and friends know how you are when they call our office.
Our main office is open 9.00 - 17.00 Costa Rican time Monday - Friday (except for national holidays). Outside of those hours, our emergency contact number is +506-8735-2392 (please leave a message if necessary).
Please understand, however, that you will be in a remote area and it is preferable that personal communications to the boat be limited to emergency use only. We also now keep a satellite phone on board, which costs $3.50 per minute.
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. Do keep in mind that in general, it is difficult to get a good signal on the island.
The vessels have both 110 and 220 volts ac. The cabins have 110 volts ac only.
The vessels have standard US and European sockets (but not British style sockets).
We have a well-equipped first aid kit including oxygen on-board. You should bring anti-seasickness medicine and ear drops if you feel you will need them.

Journey to the regions of the ocean normally reserved for scientist or military. Experience depths were no sunlight penetrates, yet life thrives. Perhaps you’ll catch a glimpse of the mythical prickly-shark .
DeepSee is a custom built submarine designed to comfortably accommodate 3 passengers, including one pilot. Once submerged, the 4 inch think acrylic dome disappears from sight and offers 360 degree views while you descent to the abyss at a maximum depth of 1500 feet.
