This 1,659-foot Historic Summit Tunnel is an old abandoned railroad tunnel and is one of the best hikes in the area. It was the railroad built by Chinese workers that completed in August 1867.
Purchased by the Land Trust in 2010 and conveyed to California State Parks in 2012 as an addition to Donner Memorial State Park, Donner Summit Canyon is the gateway to perhaps the most important square mile in California’s history.
