Cascadia State Park is a scenic forested area located at the confluence of the South Santiam River and Soda Creek, in the western foothills of the Cascade Mountains, about 14 miles east of Sweet Home. This peaceful park blends natural wilderness with thoughtfully designed landscape features and water elements.

In the early 1900s, George Geisendorfer established the Cascadia Mineral Springs Resort, which included a large hotel and landscaped gardens. The resort became known for the mineral waters of Soda Creek, which visitors drank for their believed health benefits. In 1940, the state acquired the property and expanded it to create the park.

The area is also home to an ancient Native American rock art site, with petroglyphs dating back approximately 8,000 years. Cascadia Cave, located just east of the park on private land, can be accessed by reservation through Recreation.gov with permission from the landowners.

Today, the park features a large parking area, a well-maintained campground, picnic sites with fire rings, drinking fountains, and an off-leash dog area. Two reservable group picnic areas offer covered kitchen shelters with electricity.

The Short Covered Bridge and the Cascadia Day-Use Area are located about two miles west.
