Salmon Creek Regional Park / Klineline Pond
The Salmon Creek Greenway Trail gives you miles of trails to walk. Most trails are wide paved paths, but some are gravel and dirt paths.
Note that if you park at Klineline Pond there is a parking fee. If you go 2000ft west you can park at the recreation center parking lot for free.
You can go west along the greenway trail to 36th Ave (about 3 miles), or east past Klineline Pond, under the freeway, and explore trails in the east pond area along Salmon Creek.
