Sisters State Park, State park in Deschutes County, Oregon.
Sisters State Park encompasses 28 acres of undeveloped forest land along Whychus Creek, featuring old-growth Ponderosa pine trees and diverse wildlife populations.
Louis W. Hill purchased 41 acres of land for $1,532 in 1939 and donated it to Oregon State to preserve the old-growth pine forest.
The park shares its name with the adjacent town of Sisters, which references the Three Sisters volcanic mountains in the Cascade Range.
The park property is divided into three separate parcels by U.S. Route 20 and Oregon Route 126, with access points connecting to downtown Sisters.
Whychus Creek flows through the park with seasonal water level changes that influence local fish populations and riparian ecosystems.
