The Dilworth Trail at Emerald View Park in Pittsburgh, Pennsylvania is a moderate 0.6 mile one-way trail that heads down the slopes of Mt Washington Park. The trail starts along the Emerald View Trail and connects back to it. There are various switchbacks on this trail, which make it a moderate hike.
On the flatter ground of the trail, you'll notice a decent amount of old debris, mostly tires. This land was used as a dump for a long time before being cleaned out in about 2006. Over 100,000 tires were removed from the project, but some can still be found. Most noteably, many trees have grown through the tires, leaving whole intact tires resting around the base of tree stumps that are over 20 years old.
Dogs and biking are both allowed on this trail; however, biking is likely not as easy on this one.
