Hidden Falls Regional Park is a 1,200-acre natural area in Auburn, California, centered around the 30-foot multi-tiered Hidden Falls waterfall. The park features over 30 miles of trails designed for hiking, mountain biking, and horseback riding. The landscape encompasses deep canyons and oak woodlands along the North Fork of the American River. The terrain is notably rugged, with steep elevation changes leading down to the riverbanks. The park is managed by Placer County and requires a parking permit for vehicle access. It provides limited shade in exposed canyon areas, necessitating adequate water and sun protection. Wildlife commonly seen in the area include black bears, mountain lions, and various raptors. The main viewing platform offers a direct sightline to the waterfall base.
