Dive-site story
Situated within the protected Cordillera Reef Nature Reserve east of Fajardo, Devils Key (Cayo Diablo) features a shallow spur-and-groove reef system surrounding a rocky cay. Divers navigate through fields of elkhorn and star coral, interspersed with sandy channels and mini-walls. The site remains a frequent stop for dive charters operating out of Fajardo and Culebra, offering calm, sunlit conditions sheltered from open Atlantic swells.
Extensive hard coral structures with scattered brain and boulder star corals
Frequent encounters with resting nurse sharks tucked beneath coral ledges
Sandy gullies where southern stingrays forage and hawksbill sea turtles feed
Clear channel visibility typical of the offshore Cordillera cays
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Calmer seas and reduced trade winds during late spring and summer provide optimal diving conditions across the Cordillera reserve.
