This 612 acre park, owned by the Portland Water Bureau and managed by Portland Parks & Recreation, is a natural area with meadowlands, forest and wetlands, accessible to the Springwater Trail. The park is in the headwaters of Johnson Creek, an urban creek with remnant populations of native salmon and steelhead. A 100-acre area in the southeast portion of the summit is designated exclusively for wildlife habitat with limited public access. Two underground reservoirs in the park provide drinking water storage.
There are eight miles of trails in Powell Butte Nature Park open to people on bicycles, including a mixture of unpaved singletrack, narrow, mid-width, and wide trails and paved trails. The Powell Butte Master Plan determines the allowed uses in the park and identifies the location and types of trails. The Friends of Powell Butte provide volunteer services at the park.
