Trail of Ten Falls ... Silver Falls State Park is the crown jewel of the Oregon State Parks system, being both Oregon's largest State Park (9,000 acres) and boasting one of America's most impressive waterfall day-hikes. There are no less than ten falls on this 7.8 mile loop , and most of them are flat-out gorgeous. Most of the hike are along a creek (south fork and north fork creek) and some crossing a footbridge . The hike itself is not strenuous as u hike on a wide trail and less rocky .
