Catalina Grande Dive Site — Costa Rica

About Catalina Grande

The largest island in the Catalina archipelago and a premier dive site for giant manta ray encounters. Descending along dramatic walls to depths of 40m, divers are rewarded with frequent sightings of Pacific mantas gliding through nutrient-rich waters. Devil rays, whitetip reef sharks, and massive schools of fish complete the experience.
