Renowned as one of the world’s top dive destinations, diving in Cocos Island offers thrilling encounters with hammerhead sharks, manta rays, and massive schools of jacks in the Pacific Ocean. The island features dramatic underwater walls, pinnacles, and nutrient-rich currents teeming with marine life. Divers can also spot turtles, dolphins, and whale sharks during certain seasons. Remote and largely untouched, Cocos Island scuba diving provides adventurous divers with unparalleled opportunities to explore Costa Rica’s vibrant marine biodiversity.
The prime season for diving in Cocos Island is from June to December, when ocean currents bring abundant marine life and visibility ranges from 15–30 meters. During these months, hammerhead sharks, manta rays, and schools of jacks are most active, creating breathtaking underwater experiences. The calmer period from January to April is still diveable but may offer fewer big pelagic sightings. For unforgettable shark encounters and vibrant marine biodiversity, Cocos Island diving trips are best planned in the peak season.
Accessing Cocos Island dive sites begins with flights to San José, Costa Rica, typically arriving at Juan Santamaría International Airport (SJO). From there, divers travel to Puntarenas or Golfito, where liveaboard boats depart on 3–7 day expeditions to Cocos Island. Due to its remote location, all diving is conducted via liveaboard trips, which include guided dives, equipment rental, meals, and accommodations. With professional operators and organized logistics, Cocos Island scuba diving holidays offer a once-in-a-lifetime opportunity to explore one of the most biodiverse and shark-rich waters in the world.
