Dive-site story
Carval Rock rises as a rugged, exposed formation north of St. John, offering dramatic underwater topography shaped by strong Atlantic swells and tidal flows. Divers navigate through steep cuts, large boulder fields, and deep rock ravines covered in encrusting sponges and gorgonian sea fans. The exposed location attracts open-water species, while sheltered clefts provide refuge for resting nurse sharks and schools of silver baitfish.
Dynamic rock arches and swim-through ravines carved by wave energy
Frequent sightings of cruising pelagics including tarpon and barracuda
Dense clusters of deep-water sea fans and colorful encrusting sponges
