Historic Fire Island wreck for serious boat divers.
Wreck of the USS San Diego is a historic Long Island boat dive for experienced wreck divers. The armored cruiser lies upside down offshore of Fire Island, with large entry points, a long interior, and a profile that rewards slow, careful touring. Cold-water conditions, depth, and wreck protection rules make it a serious charter site rather than a casual excursion.
