Rattlesnake Ramp is a public boat launch facility on Folsom Lake featuring a 2-lane asphalt ramp with a 15% slope and one boarding float, managed by California State Parks.

The ramp accommodates 65 parking spaces for vehicles with trailers and includes restroom facilities.

Note that water level fluctuations affect ramp usability—check current lake elevation before launching, as the ramp typically closes at 430' elevation with approximately 3 feet of water available.
