Located in the western section of Cougar Mountain Park. This long western ridge is not the highest elevation in the park. That belongs to Wilderness Peak. But the De Leo Wall has the best view in the park and arguably the most exciting terrain in the park. Located just outside the southwest border De Leo Wall features a great view towards the southwest of towns like Kent, and Renton. On a good day you can see much further with the Olympics coming into view. Well worth the 10-15 minutes to the Red Town Trailhead from Seattle.
What makes this little peak/ridge so desirable outside of the view are the two trails that extend from the viewpoint. One trail heads north to the true summitof Marshalls Hill while the other trail traverse the very steep south side of the De Leo Wall. It is the closest thing to a catwalk in the Cougar Mountain Wildlife Park and actually come to a surprise to the casual hiker and trailrunner. I would recommend taking this trail for the views and the semi-catwalk feel but I wouldn't advise running on it. The other trail that travels straight uphill to the true summit of De Leo Wall is not very scenic but it does attain the summit and quickly catchs up with the other trail.
A roundtrip route on the De Leo Wall is usually 4 miles and can be done from an hour by a very fit hiker to three hours by a very casual hiker. Often people combine De Leo Wall with side trip to Coal Creek Falls for maximum scenery overload.
