Granite Bay Main Beach (Folsom Lake)

Granite Bay is the largest day-use area on Folsom Lake, at the end of Douglas Boulevard in Placer County. California State Parks runs it as part of Folsom Lake State Recreation Area. It combines the Main Beach swim and picnic area with one of the lake's main boat launch complexes, so swimmers, picnickers and trailer boaters all share the area on summer weekends.

Layout

A large lot serves the Main Beach, with accessible spaces, two unisex restroom buildings, a snack bar and equipment rentals. Picnic sites line the shore when the lake is full. Group picnic site A is at the south end of the Main Beach lot. The launch complex has four ramps, boarding floats and parking for about 920 vehicles with trailers. The Stage 4 ramp has its own restrooms and a shaded picnic area when the lake is full.

Water level

Folsom is a reservoir, and many shoreline facilities are only usable at full pool. Check current lake levels before you go.

Rules to know

Dogs aren't allowed in the Granite Bay swim area, and alcohol is banned in all day-use areas and on the lake surface except on registered vessels. Swimming isn't allowed within 500 feet of the launch ramps, and skim boarding isn't allowed on designated swim beaches. Trailered and motorized boats must carry a golden mussel quarantine or decontamination seal before launching.
