Overlooking the Tualatin River Valley, the new Cooper Mountain Nature Park sits on the southern edge of Beaverton, shouldered by dense urban development to the north and open agricultural lands to the south. The 231-acre park offers visitors 3 1/2 miles of gravel trails traversing the park's rare habitats and natural features. Cooper Mountain Nature Park is operated through a partnership between Metro and the Tualatin Hills Park & Recreation District.

What you can do at Cooper Mountain Nature Park

Hike, walk, watch wildlife or simply enjoy the views when you visit Cooper Mountain Nature Park with your friends or family. More than three miles of trails with varying levels of difficulty traverse the park and include a 3/4-mile loop that is designed for accessibility.

The trails pass through each of Cooper Mountain's distinct habitats – from forest to prairie to oak woodlands. From these trails, visitors are rewarded with grand views of the Chehalem Mountains and Tualatin Valley, close-up looks at Oregon white oaks and wildflowers, and – if you are quiet and lucky – glimpses of rare animal species like the Northern red-legged frog and Western gray squirrel.

The park includes accessible restrooms and a Nature House for environmental education programs that will serve as a base for staff and volunteers. A demonstration garden located next to the nature house will showcase native and drought-tolerant plants suited to Cooper Mountain's dry climate and south-facing slopes. The plants have been selected to give back yard gardeners new ideas to try at home. More about natural gardening

For the benefit of wildlife please, leave your pets at home. No alcohol, smoking, bikes or equestrian use are allowed within the park. Bike racks are available near the Nature House. The park is open daily, dawn to dusk.

Park stewardship a joint venture

The Tualatin Hills Park & Recreation District provides day to day management at Cooper Mountain Nature Park. This includes park ranger operations, security service, educational programming, park maintenance and natural resources management. Voter-approved funds allowed Metro to purchase land on Cooper Mountain beginning in 1997. More land acquisition followed until 231 acres were under Metro's protection and care. Since that time, the natural area has been undergoing active restoration and land management. Volunteers have participated in nearly every aspect of Cooper Mountain's transformation – removing invasive species, restoring native grasses and wildflowers, planting more than 110,000 trees and shrubs, enhancing the oak woodlands and improving the small quarry pond. Metro's science team will continue to lead restoration activities at Cooper Mountain. Park development was funded through Metro's voter-approved 2006 natural areas bond measure and a grant from Oregon State Parks.
