Before you arrive

Access notes

Florida Keys National Marine Sanctuary states that historical sites in the sanctuary are open to diving and snorkeling. Exact access, mooring availability, protected-zone rules and conditions must be confirmed before departure.

Plan within your training

Conditions and hazards

Open-water hazards include current, waves, boat traffic, entanglement, sharp or unstable wreckage, overhead temptation, depth, narcosis and limited emergency response. Never penetrate wreckage without the appropriate training, equipment, gas plan and permission.

Independent resource notice

This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
