Highlights
The Okeanos Aggressor II liveaboard was built for comfort and stability to offer year-round diving at the remote islands of Costa Rica. The yacht provides comfortable accommodation for 24 guests in 12 en-suite cabins. Eight deluxe staterooms are located on the lower deck, and there is a double lower bed and twin upper bunk-style bed. On the main deck is the master stateroom with a queen bed, and on the upper deck are two suites that have either two twin beds or one king bed.
On the main deck is the ship's restaurant, where delicious cuisine with a varied and plentiful menu is served. Breakfast and lunches are buffet-style, and dinner is chef-prepared and served each evening. On the top deck is the BBQ and shaded cocktail bar, perfect for unwinding with fellow guests to discuss the spectacular diving of the day. Here, you can also find comfortable loungers to do some tanning in between dives.
The Okeanos II liveaboard departs from Puntarenas, Costa Rica for the 36-hour crossing to Costa Rica. Guests can enjoy up to 21 dives at the UNESCO World Heritage site for the chance of big fish encounters like nowhere else. Aside from the incredible diving, guests will also be taken ashore to hike through the jungles of Cocos and swim in the many waterfalls.

As good as indonesia on some dive sites
some sites had several schools of different kinds of fish, as well as sharks and turtles, all in one dive. I like to watch schools of fish. I have been to Indonesia on many dive vacations and Cano Island is as good as Indonesia for schooling fish on some dive sites.

Enchanting island teeming with under the sea life...amazing!
Seeing a Manta Ray, hammerheads, marble rays, spotted eagle rays, a Galapagos shark and the whale shark on Easter morning first dive of the day with dolphins playing in the water when we boarded the panga. Yes, all of this on one dive...spectacular!

Trip of a lifetime
The diving exceeded expectations, the crew was so hospitable and went out of their way to make sure we lacked for nothing, and the food was the best I've ever had on a liveaboard. The only criticism, is that the boat's common areas could use a little updating.

Truly a once in a lifetime experience.
Unbelievable diving with bunches of sharks at every site. Because we were at the end of the dry season there was little rain and calm seas making for a pleasant crossing and opportunities to visit the island. Can't say enough about the crew, they are dedicated to making your experience an enjoyable one.

10/10 would go again
This was a fanstic trip to spend time with my brother and meet new friends. The diving was superb, never a dull dive day. The crew were always willing to help and were very friendly. The chefs and the food were amazing, no doubt I gained a few kilos on my vacation :). Even though some days the weather was not ideal, the crew and the dive guides did their best to still offer the best experience in and out of the water.

Big animal life not as abundant as expected/anticipated
Overall, boat, food and crew were great. White tip sharks abundant, other shark life averaged 1 or 2 per dive, with Galapagos, black tip, hammerhead and tiger sharks. Limited sites around Cocos. Crossings were better than expected. Water was very warm, 3mm wetsuit fine, but probably why the bigger life was limited, El Niño conditions?
