Cooper Mountain Nature Park

Overlooking the Tualatin Valley, the 230-acre Cooper Mountain Nature Park offers visitors grand views of the Chehalem Mountains (and features 3½ miles of trails of varying difficulty) that traverse the park and pass through a mosaic of distinct habitats: oak and madrone woodlands, native prairies, and conifer forests.

Along these trails, visitors may catch glimpses of rare animal species like the Northern red-legged frog and Western gray squirrel. Nature lovers can get up-close looks at Oregon white oak trees, and view a small prairie that has sat relatively undisturbed for hundreds of years.

This park includes a natural demonstration garden, showcasing native and drought-tolerant plants suited to Cooper Mountain’s dry climate and south-facing slopes. The park also has picnic tables and a nature play area for children. The Cooper Mountain Nature House offers year around environmental education programs and is available for rentals.
