Okeanos Aggressor (click for details)

Some of the best diving in the world!  Situated 342 miles off Costa Rica's Pacific coast, Cocos Island is A World Heritage site and it's rocky pinnacles are beacons for big animals and big action. Schooling hammerheads, countless white-tip sharks, mantas, tuna and even whale sharks call Cocos home.  Cocos Island is a World Heritage site and an amazing place to go 


The Okeanos Aggressor sleeps 22 guests in 9 deluxe staterooms (with double bed lower and twin bed upper), 1 master deluxe stateroom with a queen bed, and 2 suites of which one has two twin beds and the other a king bed. 

All rooms are air-conditioned and fitted with private toilets, showers and sinks. Breakfast (cooked to order), buffet lunch and an elegant chef prepared meal at dinner with tableside service are served in addition to fresh mid morning and mid-afternoon snacks. Beverages (alcoholic and non-alcoholic) are complimentary while onboard. The yacht is equipped with hairdryers in each stateroom. Linens are changed mid-week and fresh towels are placed in each stateroom as needed.


Once on board the boat leaves port for the 36 hour boat ride to Cocos Islands .  Conditions can be choppy so do bring medication if you are prone to seasickness.   Once moored at Cocos the diving begins!   Diving is characterised by walls and pinacles which attract large numbers of sharks and other pelagics and huge shoals of fish.   There are up to 4 dives per day and up to 24 in the 10 day trip.  Night diving is currently not permitted on Cocos Island.

The diving Cocos can be challenging with strong currents and divers must have at least 40 dives and have a reef hook and SMB & reel.


The water is approx 22 degrees so a long 5mm wetsuit, thermal top and hood is recommended.  Gloves are a good idea to protect your hands and a  reef hook is a must as there are strong currents.

See the Okeanos Aggressor website for many more details and particularly their detailed 'Know Before You Go' fact sheet.
