Located off Costa Rica’s north Pacific coast near Flamingo, the Catalina Islands are a stunning volcanic rock archipelago that offers some of the most diverse and exciting scuba diving experiences in the region.

​

Situated just 7 miles offshore, these islands are surrounded by nutrient-rich waters, thanks to dynamic ocean currents. This creates a thriving marine ecosystem, making the Catalinas a must-visit for underwater enthusiasts seeking unique marine life encounters.

​

The Catalina Islands diving spots are renowned among the top three dive destinations in Costa Rica. Divers can expect to see fascinating marine life, including white-tip reef sharks, hawksbill and green sea turtles, and various species of rays such as eagle rays, mobula rays, and the iconic oceanic manta ray.

​

Manta rays are one of the most sought-after highlights of diving in this area. While sightings can occur year-round, these graceful giants are most commonly seen between December and June, creating unforgettable moments for divers.

​

Another incredible feature of the Catalina Islands is their seasonal visits from humpback whales. These majestic creatures migrate to Costa Rica’s warm waters twice a year to give birth. Northern hemisphere whales arrive from January to April, while southern hemisphere whales can be spotted from August to November.
