Acorn Creek Trail Run

The Acorn Creek Trail Run takes place at Salmon Falls Ranch near the Acorn Creek Trailhead east of Folsom Lake. The trailhead and ranch are privately owned and maintained by the American River Conservancy, and the event is directed by the Bizz Running Company as a fundraiser for the conservancy. Proceeds support trail work and maintenance in the Acorn Creek / Salmon Falls Ranch area. Salmon Falls Ranch contains miles of single track trails, creek crossings, climbs, and views that the course uses.
