The 1,200-acre Hidden Falls Regional Park (Hidden Falls) is located between the communities of Auburn, Lincoln, and the Ophir/Newcastle area. The park is situated along the Coon Creek and Deadman Creek watersheds, and is south of the Bear River. Hidden Falls Regional Park was purchased by Placer County through the Placer Legacy Open Space and Agricultural Conservation Program for the purposes of natural conservation and passive recreation.
Hidden Falls offers 30 miles of multiple-use trails, two observation decks allowing close-up views of 30 +/- foot waterfalls, picnic areas, and fishing access. There are sweeping views of the Sacramento Valley to the Sutter Buttes and beyond.
