Okeanos Aggressor II
Costa Rica, Cocos Island & Malpelo Island
Where thrilling encounters and raw beauty await beneath the waves.
The Okeanos Aggressor II is your gateway to one of the last truly wild diving destinations on Earth. If you're ready for big animals, remote diving, and unparalleled adventure, Cocos Island is calling.
Located over 300 miles off the Pacific coast of Costa Rica, Cocos Island is a UNESCO World Heritage Site known as one of the planet’s top destinations for big-animal diving. This uninhabited island, surrounded by deep ocean currents and nutrient-rich waters, is a magnet for pelagics and a true bucket-list destination for advanced divers.
Expect adrenaline-pumping drift dives through towering underwater pinnacles, where massive schools of scalloped hammerheads, whale sharks, manta rays, tiger sharks, and silky sharks cruise in the blue. With visibility often exceeding 30 meters and water temperatures between 75–84°F (24–29°C), every dive is a chance to witness nature’s rawest moments in one of the world’s most remote marine reserves.
Best diving conditions typically occur from June through November (for larger marine life and action-packed dives), though December through May offers better visibility and calmer seas.
Departures year-round from Puntarenas, Costa Rica.
Due to the island's remote location, crossings take approximately 32–36 hours each way, leaving you with 7–10 full days of diving depending on the itinerary.

• 10 or 12 nights onboard accommodation in your chosen stateroom
