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.

The trip was awesome and highly recommended for anyone seeking great adventure!!!!
The trip was amazing. The crew is outstanding and everything is always prepared, and there are never any issues or excuses. The food is over the top and the presentation is 5 star for liveaboard life. They are very professional. One of our dives was one of the best in my life with hundreds of hammerheads and a Whaleshark. We also encountered about 40 marble rays in a mating frenzy which was fascinating. Overall great experience.

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!

Fantastic trip. Highly recommended.
Going in April you get benefit of better conditions, warmer water, calmer crossing and less current. This comes with the trade off of less big groups of pelagics. That said we had plenty of great encounters with hammerheads, galapogas, silky, black tips, dolphins, eagles and Mantas. They were almost all lovely doves. The team was excellent, in particular Luis and Facundo as dive guides, Esteban and Gerardo as the chefs and Giancarlo on hospitality. I’ve been on 6 liveaboarda and the food was the best I’ve had, incredibly sushi nights, steak and many more. The boat is older but incredibly solid. Most of the negative reviews I’ve read were on the boat, yes the cabins are a bit ‘cozy’ but I knew this going into and didn’t mind. Overall the boat is in great structural condition, everything works very well it just has slightly dated decor and smaller cabins.

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.

One of those bucketlist destinations...Has to be done at least once!
Diving against the classic 'wall of hammerheads' on Dirty Rock and getting up close with my first two tiger sharks. Everything is also super sized here, the sharks, the enormous (!) schools of fish, the multiple rays (we had two surprise mantas our week). Note that the boats travelling to Cocos are more simple than most of the luxury liveaboards you get in e.g. the Red Sea and Maldives, but hey, you have everything you need and who cares when diving this great!

A dive site that deserves its place in the world top
An overall positive experience thanks to an exceptional dive site and a quality service especially in terms of catering. I was able to observe all the marine fauna I had come to see: hammerhead sharks, Galpagos and Silver tips sharks, whale sharks and manta rays. Lots of beautiful memories thanks to a group of divers and a friendly team. The few negative points are related to the comfort on the boat: very rudimentary outdoor spaces, a slightly old boat and too much air conditioning in the cabins that it is impossible to adjust individually.
