A connector trail between Wildside and De Leo Wall trails on Cougar Mountain.
Marshall's Hill Trail stretches from the Water Tank access road above Newcastle's 146th Place SE east to the intersection of Red Town Trail and Indian Trail. It's length is 1.1 miles (not counting the 0.1 mile walk up 146th and the Water Tank access road).
Except for the eastern-most portion, the trail is fairly flat and winds through tall trees and over think roots. Although it is near developments, you rarely see houses.
