10 or 12 day Cocos Island diving adventure

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, Jacque Cousteau pronounced Cocos, "The most beautiful island in the world."

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.

Sample Itinerary:

Arrival Day

Take a shuttle to Adventure Inn and relax for one night.

Day 1

The first day of your tour, you will be picked up at Adventure Inn and transferred 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 Adventure Inn. We strongly recommend booking one more night on land, before flying out, in case of any unforeseen delays.
