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.
