 Silver Falls State Park At over 9,000 acres, Silver Falls State Park is Oregon's largest park and a veritable bonanza of stunning sights and scenery. Scenic walking trails for hikers and non-hiker of all levels guide trekkers throughout the park as they pass by lush forests, open fields, and waterfalls. If you'd prefer to bring a bike, Silver Falls offers multi-use bike trails that encompass the park. If you make the trip, be sure to visit the Trail of Ten Falls, the park's most popular spot for both hikers and photographers alike. This trail takes visitors on a stunning eight-mile journey past some of Silver Fall's most notable waterfalls. Incredible!
