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.

Great diving. Great food. Brilliant adventure
Diving was brilliant. Cocos Island is cool, so many waterfalls. The diving was really well organised, the staff on the boat worked really hard. We were worried about the food, as my husband has Coeliacs, but the attention to detail on this was superb, they brought out gluten free options whenever required. Also the staff at Liveaboard.com were great, they jumped straight onto a mix up with my booking, it was really easy to get hold of them on the phone, and the mix up was sorted straight away.

PuraVida in this JurassicPark like environment
What a special island, and a special feeling to be lucky enough to have been there. Crew was amazing, dives were warm and with good viz, many hammer heads around, eagle and marble rays, dolphins etc... although the best season apparently ranges from August to October, with colder waters and loads of sharks. PuraVida !

Spectacular dives
The 36-hour sailing is well worth it. Extraordinary dives especially on the dirty rock site with a spectacular school of jack fish, and an unforgettable school of hammerhead sharks.

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.

Fantastic trip and experience
We had amazing dives in Cocos with a great group and friendly staff. We saw lots and lots of hammerheads up close and personal. Excursions on land were fun. Food was plentiful and had a nice variety of options. Ride out was 41 hours and rough, but our ride back was 36 hours, smooth and sunny. Overall was a fantastic trip and experience. Cocos is truly a special place.

The diving was very good, albeit tricky at points and we were well looked after. The boat was tired with small communal eating and hangout spaces, kitting up area and cabins
