A liveaboard trip to Cocos Island transcends the typical dive vacation. It is an expedition to an aquatic wildland that has been left largely untouched by human hands. Each dive is a journey back in time to an ocean that teems with life and diversity, providing a deep and meaningful connection to the natural world. Cocos Island is not just a place to dive; it is a place to become one with the ocean's pulse.
The Cocos Island haven is not only a sanctuary for flora and fauna in Costa Rica but also a haven for eco-tourists and adventure seekers. The nation's commitment to preserving its natural treasures is evident, with approximately a quarter of its land protected within national parks and reserves.
Cocos Island boasts a history shrouded in tales of buried pirate treasures, most famously linked to the legend of the Treasure of Lima. It is said that hundreds of gold statues, religious artifacts, and immense wealth were stashed away by a pirate named Benito Bonito in the early 19th century, though no treasure has ever been found. The island’s rich history and stunning biodiversity were the inspiration for Michael Crichton’s novel, and later Steven Spielberg’s film, "Jurassic Park."
Embarking from Puntarenas in Costa Rica, the passage to Cocos Island aboard a liveaboard is the beginning of what promises to be an epic underwater adventure, one that takes around 36 hours across the Pacific and is the only way to access this remote and pristine island sanctuary.

The ideal months for a Cocos Island liveaboard excursion are between June to December. During the wet season, nutrient upwellings attract dense shoals of hammerhead sharks, whale sharks, and other pelagics. Visibility ranges from 60 to 100 feet, and water temperatures average between 72 and 82°F. The dryer season may offer calmer seas and better visibility but fewer large marine encounters.
Divers should be prepared for strong currents and potentially challenging conditions, which are part of what makes Cocos Island so special. These currents are the lifeblood of the island, bringing in the nutrients that support its rich marine ecosystem.
