Visitors to Cooper Mountain Nature Park will be rewarded with grand views of the Chehalem Mountains, close-up looks at Oregon white oaks and a small prairie that has sat relatively undisturbed for hundreds of years. The site features 3½ miles of trails (with varying levels of difficulty) that traverse the park and pass through each of its distinct habitats - from conifer forest to prairie to oak woodlands. Dogs and other pets are prohibited for the protection of area wildlife.
Metro and THPRD work in partnership to provide habitat restoration, wildlife monitoring, maintenance of hiking trails and nature education programs to visitors of all ages.
