Lake Cuyamaca Boat Ramp offers public access to the lake with a single launch ramp, one boarding float, and 20 parking spaces for vehicles with trailers; boats must be between 9-26 feet in length.

All private boats and equipment require ranger inspection for invasive mussels before launching, with a $8 launch fee.

The ramp operates seasonally (currently 8am-5pm Mon-Thurs, 6am-5pm Fri-Sun), though it was closed as of November 2025 due to low water levels, with kayaks still permitted if carried to shore.
