The name comes from the silver shells that trim 2.5 miles of the ocean-side shoreline. State Route 75 runs the length of the strand and is used for jogging and cycling, and the Silver Strand Half Marathon is held along the route each November.

Silver Strand State Beach lies 4.5 miles south of Coronado on State Route 75, which runs the length of the strand and is used for jogging and cycling. The park has four large parking lots holding up to 1,000 vehicles, and about 130 campsites are first come, first served. Beaches north and south of the state beach are Department of Defense property.

The waters support a variety of fish species, including perch, corbina, and grunion that swim to the beach under certain conditions. This natural fish diversity draws anglers and nature observers alike.
