Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Guided land-based and day-boat scuba around Red Hook, Secret Harbour and Cruz Bay combines shallow reef instruction, boulder passages and selected wrecks. Red Hook Dive Center, Aqua Action and Low Key Watersports publish local dive options. Cow and Calf Rocks and Carval Rock can have currents or more challenging contours; the Cartanza Senora wreck is a qualified guided outing, not permission for penetration.
Carval Rock
A local boat dive characterized by dramatic rock structure and variable current; a conditions- and skill-dependent stop rather than a guaranteed beginner site.
Secret Harbour reef
St Thomas shallow training and shore-diving option described by Aqua Action; operator activity and shore access must be rechecked.
Grass Cay waters
St John-area local boat diving mentioned by the island tourism guide; use licensed operators and check current routes, park boundaries and conditions.
Cow and Calf Rocks
St Thomas-area rock and boulder passages described by Red Hook operators and the tourism department.
Cartanza Senora
St Thomas wreck-area diving reported by tourism and Red Hook dive guides.
Eagle Shoal
