A journey through time and space

The trip to Cocos Island in Costa Rica aboard the Okeanos Aggressor II was unforgettable. With a friendly, helpful and knowledgeable crew of the operation, we were able to visit this magical destination that transports one in time and space. On the trip we shared with people from several countries around the world in a very pleasant atmosphere, being able to visit fantastic diving spots where we saw multiple species of pelagic animals from the Pacific Ocean.

Perfect sport for shark lovers

Cocos Island is a fantastic option for shark lovers due to the variety you can find at each dive. It is a long trip from Costa Rica but completely worth it. The crew did a great job to make sure we all felt comfortable. Special mention to the chef and his assistant, who amazed us every day with fantastic dinners.
