The Blackrock Summit Trail at Shenandoah National Park in Crozet, Virginia is an easy 1.2 mile loop hike that leads out to Blackrock Summit. The trail starts off along the Appalachian Trail (white blazes) to the summit, which is only about 0.5 - 0.6 miles one-way. The summit gives you an almost-360 degree view of the southern Shenandoah area and a large rock scramble to climb if you want to take in panoramic views.
Continue on the trail and take a left at the sign post just beyond the summit area to return to the parking lot. The final hike out follows the blue blaze trail. Dogs and camping are both allowed on this trail - there were small areas along the Appalachian Trail here where thru-hikers can setup camp.
