Cascadia State Park
Cascadia State Park is a state park in the U.S. state of Oregon near Sweet Home along the South Santiam River at Cascadia. The park includes a day use area, campsites, hiking trails and 150 foot Lower Soda Creek Falls. History. Prior to settlers arriving, groups from the Molalla and Kalapuya tribes visited the park site to harvest huckleberries, fish and hunt. Cascadia Cave is nearby. The cave is an 8,000-year-old American Indian petroglyph site considered to have the largest concentration of rock engravings in western Oregon. Willamette Valley settlers developed a bypass at the  park site for horse-drawn wagons. Old wagon ruts are still visible near where Soda Creek meets the South Santiam River. In 1896, George Geisendorfer opened a resort to capitalize on what he called the "curative powers" of Soda Creek's mineral spring water. The resort included a hotel, tennis courts, croquet course, garden and bowling alley. The hotel later burned and the property was acquired by the state of Oregon in 1940. Hiking trails. Cascadia State Park includes two primary hiking trails. The one mile Soda Creek Falls Trail follows Soda Creek to Lower Soda Creek Falls. The 3/4  mile loop River Trail descends to the South Santiam River. Flora. A forest canopy of Douglas-Fir, cedar and hemlock shades the ground, encouraging the growth of ferns, mosses and mushroom species. Wildflowers include Oregon trout lily, fairy slipper, western trillium, camas, fawn lily, Hooker's fairy bells, snow queen, false Solomon's-seal, stream violet, Oregon Iris and Pacific bleeding heart. Access. The park is located along U.S. Highway 20 14 miles east of Sweet Home and 59 miles west of Sisters.
