Columbine Trail
The Columbine Trail at Duff Park in Murrysville, Pennsylvania is an easy 0.2 mile one-way trail that leads to/from the parking lot and up to the Trillium Trail.While the uphill climb isn't flat, it's not particularly difficult, hence the easy difficulty. The trail is marked with blue blazes all the way until you reach the Trillium Trail.
Dogs are allowed on this trail, but no biking. Doggy bags can be found at the trailhead by the parking lot too.
