Saint Croix offers a diverse roster of dive sites that rewards every level of certification. Wrecks such as Butler Bay Wrecks and Armageddon sit alongside sloping reef walls at Eagle Ray and Green Cay Slope, while Frederiksted Pier delivers classic muck diving beneath its pilings. Vertigo adds a dramatic wall drop for advanced divers.
