Protected harbor wall for night dives.
State Harbor is a protected Stock Island harbor wall with a steep drop and shore entry possible. It is more of a local utility dive than a reef destination, but that makes it useful for night dives and simple practice sessions. Expect boat residue on the surface and lobster activity around the wall rather than big coral scenery.

Safety Notes
Use a diver-down flag, watch boat wake, and treat it as a local harbor dive rather than a reef run.

Shore entry is possible, but it is a working harbor with boat lanes and local lobster activity.
Legal Notes
Keep a diver-down flag up and respect Key West harbor traffic rules and clearance requirements.
Community notes to help plan your visit.
Scuba Diving
Often used for night dives.
Freediving
Not a standout freedive site; the wall and harbor traffic make it better for short controlled descents than for longer breath-hold dives.
Snorkeling
Possible near shore, but the wall and working boats make it less appealing than the Keys' reef snorkel sites.
