Nature Park Guidelines
Trails are open daily sunrise to sunset.
Because the Tualatin Hills and Cooper Mountain Nature Parks are managed as wildlife
preserves, dogs are not allowed. Dogs on leash are welcome on the Westside Trail and
in all other THPRD parks.
Please...
• Ride bikes on paved trails only. Limit speed to a walking pace.
• Keep wildlife wild. Observe animals in their natural habitat and avoid feeding wildlife.
• Leave plants, mushrooms, and animals where you find them.
• Minimize your impact on sensitive habitat by staying on established trails.
Be safe: Report suspicious behavior to Park Patrol: (971) 246-0169
Continue your exploration of nature year-round!
We offer nature programs for all ages: preschool, camps, guided hikes, scout programs,
school field trips, volunteer opportunities, and much more!
