Silver Falls State Park is a state park in the U.S. state of Oregon, located near Silverton, about 20 miles east-southeast of Salem. It is the largest state park in Oregon with an area of more than 9, 000 acres and it includes more than 24 miles of walking trails, 14 miles of horse trails, and a 4-mile bike path. The park's most visited waterfall is South Falls, a 177-foot (54 m) cascade. Remote Double Falls, however, is listed as the highest waterfall in the park, plunging 178 feet (54 m) in a small tributary side canyon deep within the Silver Creek Canyon
