Rossmoor Bar is a peninsula-bordered park on the American River in Rancho Cordova offering raft launching areas both above and below the Class-II San Juan Rapids, making it ideal for inexperienced rafters and small watercraft paddlers to avoid challenging sections.

The site features picnic areas, restrooms, a pedestrians-only trail to the river, and comfortable clay banks for anglers to fish from. Access is via Coloma Road or El Manto/Rossmoor Drive from Highway 50, with year-round parking available for $7 per vehicle.
