Compton Peak

Compton Peak is a 2.4-mile round-trip hike from Compton Gap, climbing south on the Appalachian Trail before branching onto two blue-blazed spurs. The west spur reaches a rocky viewpoint over the western Blue Ridge; the east spur continues to an outcrop of polygonal rock columns. It’s a good pick if you want a short hike with a real climb and an unusual geology payoff. The route is moderate, and the usual outing takes about 1 hour 45 minutes; give it closer to two hours if you stop at both spurs and spend time looking at the rocks.

Cross Skyline Drive from Compton Gap Parking Area at mile 10.4 and follow the A.T. south. The climb is steady, with switchbacks through forest, until the blue-blaze junction roughly 0.8 mile from the start. Turn west at the junction for the rocky viewpoint, then retrace that spur. Continue east to the second viewpoint; the columnar jointing is farther down, below the cliff, so keep following blue blazes around the large boulder. Return the same way to the lot. This is an out-and-back with two side trips, not a loop; the 2.4-mile total covers both viewpoints and the descent to the columns.

Its final descent is steep, rough, and rocky, with uneven footing around the outcrop; it’s the most demanding piece of this otherwise short hike. You can turn around at the east viewpoint if that descent isn’t a good fit. The trail is not ADA accessible. Dogs may come on a leash no longer than six feet.

The west spur is the better stop if you want a view: its open rock looks west across the Blue Ridge toward the Valley and Ridge. The east viewpoint is less open, but the lower rock feature makes the hike distinctive. For a photo, frame the polygonal rock faces with a tree or canopy in view to show their scale.

These columns are part of the Catoctin Formation, made from lava that spread across the region about 570 million years ago as tectonic plates began pulling apart along distant rifts. There were no volcanoes here; the source rifts lay well east of Shenandoah. As basalt cooled and contracted, it cracked into the angular, column-like pattern you see at the cliff base. Later, heat and pressure during Appalachian mountain building changed the rock’s minerals and texture into greenstone. The cracks formed as the rock cooled, rather than being carved into it later.

The trailhead is the Compton Gap lot on Skyline Drive; the A.T. marker is across the road, so cross over to begin. The park entrance fee applies, but the hike itself has no extra fee or reservation. Food and drinking water at the lot or on the route weren’t confirmed, so don’t count on supplies there. The named route fits into a Skyline Drive day, but the steep east spur can make the outing feel longer than its mileage suggests.
