An urban hike around the hills in northwest Corvallis This hike and be started from any part along the route, but I like to start at 29th and Roosevelt Drive. From here head west up Roosevelt hill, then left on Elmwood, then a right on Dogwood which comes down the hill to Circle Blvd. Take a right on Circle and head up your second hill which tops out on Witham Hill Drive. Cross over Witham Hill Drive and head down Circle till it ends at a paved bike path. Follow the path till it ends at Harrison Blvd. Take a left and follow the sidewall to 36th Street. Take a left and head up 36th till it ends at Grant then take a left and start up your 3rd hill on Witham Hill Drive (again). Take a right on Circle and go back down the hill till you hit 29th Street. Take a left and go up the small 29th "bump" and back to your starting point.
