Day 1
Your adventure begins with a warmly welcome on Okeanos Aggressor II and help you settle in. After a refreshing drink and a comprehensive safety briefing, the liveaboard will begin its long crossing, approximately 36 hours at sea, toward the legendary diving paradise of Cocos Island.
Core Days
This is where the magic begins. Over the next 9 days, you will explore the remote waters surrounding Cocos Island, famous for some of the most thrilling big-fish encounters on the planet.
The highlight of every dive is the chance to witness massive schools of scalloped hammerhead sharks, often numbering in the hundreds. But they are far from the only stars of the show. You may also encounter whitetip reef sharks, Galapagos sharks, tiger sharks, silky sharks, whale sharks, and even the occasional silvertip or guitar shark. Rays of all kinds glide gracefully past the cleaning stations, including mobula, marble, eagle and manta rays, while huge schools of Pacific fish such as creolefish, trevallies and jacks add to the spectacle.
Your days follow a balanced rhythm, filled with exciting encounters beneath the surface. Each morning begins with dives where you can expect to see schools of hammerheads and other pelagic species moving gracefully through the currents. Afternoons often bring the chance to spot whale sharks, especially between June and September, along with large schools of fish and passing rays. Evenings are reserved for unwinding, reviewing photos, and sharing stories with fellow divers, as night diving is not permitted in Cocos due to the presence of hunting tiger sharks.
Please note that the first and last diving days at Cocos, Days 2 and 10, feature partial schedules due to the timing of the boat’s arrival and departure from the island.
Day 11
After an unforgettable journey, Okeanos Aggressor returns to Puntarenas. Following a light breakfast, you will disembark and be transferred back to your hotel in San José or directly to the airport, carrying with you extraordinary memories of Cocos Island’s wild underwater world.

Equipment at the right size were available and at good condition. Staff were incredibly friendly and helpful. Liveaboard is a little bit on the "ageing" side but this is compensated by the great service and food that we received." -

"
This trip has surpassed my expectations. Probably the best, most organized trip I have ever been on. Staff was extremely friendly and accomodating. We were treated like royalty. Our wishes were their quest. All details were paid attention to. Safety was their number one concern. The diving was beyond words. It is definitely worth every penny and worth travelling the distance. BTW, the food was out of this world. Cant wait to go back." -
