Cooper Mountain Nature Park

Located in Beaverton, Cooper Mountain Nature Park offers visitors a 230-acre of diverse habitats with 3.23 miles of beautiful trails, a natural play area, and expansive views.

We are happy to share more local hikes and adventures, to help you with some ideas of where to go! More urban forests close to home.

We’ve visited Cooper Mountain Nature Park several times, and despite the seasons, every time we discovered new things to appreciate and enjoy.

This time, for instance, we loved walking in the trails full of unusual wildflowers!

What to see and do

Cooper Mountain Nature Park is one of those places that we considered as our family’s all-time favorite since it features trails, play, and picnic areas in the same location.

Imagine all those amenities included with the addition of amazing views and natural habitats to explore. Perfect adventure!

This 230-acre park is mainly used for hiking, running, and nature trips.

Located about 30 mins from Portland, it offers 3.23 miles of trails that will lead you to explore different landscapes where you can learn about local wildlife and plants.

After parking, you will find the Nature House, restrooms, picnic tables, and the play area. My kids love that playground!

In general, we always do the hike first, and then we return to the play area to have our picnic and continue playing.

The hike

From the parking lot and after passing the playground you will find an information kiosk with the map and other important rules.

• 

While walking in the trails you will have the opportunity to enjoy different landscapes and habitats like prairies, forests, and oak woodlands.

Additionally, at different points of your hike, you will be delighted with the views of the Chehalem Mountains and Tualatin Valley!

After taking a look at the map you can explore the park trails in different orders.

However, in general, we love to walk first on the little prairie loop (designed for accessibility) where you will find for instance Douglas-fir woods and oaks, and a viewpoint of the prairie with an interpretive sign and benches.

• 

Next and back to the junction, you can take the Blacktail Way that includes more forest and woodlands. We loved to walk there.

In the following junction, go left to the Cooper Mountain loop and then take the Larkspur Loop where you can see those beautiful flowers (late Spring).

After completing the loop and coming back to the trail junction, go left to the Cooper Mountain Loop to start the last section of the walk, coming back to the parking area.

Worth noting that every trail junction has a directional marker; it’s super simple to walk on this park.

Summarizing, it’s a peaceful and delightful hike that the entire family will love.

As a temporary rule, THPRD is implementing one-way trails here to promote social distancing. See the modified map.

Finally, If you love natural areas, wildlife refuges, and preserves, you will enjoy some or all of these options.

Stay safe and happy hikes!
