The Inner Loop Trail at Bullock-Pens Park in Pittsburgh, Pennsylvania is an easy 1.3 mile hike that runs end to end from the two main parking lots. While this trail is shorter and has less to offer than the Outer Loop Trail, it's still a nice walk through the park.
The trail sits higher up on the hillside, so you get views of the park and creeks below. Dog are allowed on this trail.
