Raven Rock is an out crop of rocks with a splendid view. It is located along the Appalachian Trail less that .5 miles north of Raven Rock Hollow Rd.
Raven Rock can be reached from the north or south along the Appalachian Trail. The hike from the south is only about .2 miles making it an easy excursion. From the north you'd hike almost 6 miles starting at Pen-Mar. and cross over High Rock
and the side of Quirauk Mountian.
To start at Pen-Mar take Interstate 70 at exit 35 take MD 66 North to Cave Town. Turn right on MD 64 and continue north to MD 418 (Ringold Pike) turn right at this intersection. Immediatly after crossing into Pennsylvania turn right on Harbaugh Church Rd. A short distance later turn right on Old Pen-Mar Rd. The Appalachian Trail will cross the road with limited parking just past the trail.
From the South via the Appalachian Trail starting at Raven Rock Hollow Rd (MD 491). This road can be found a few miles North of Cave Town on MD 64. However there is no parking available where the trail crosses the road other than along the road side.
The only access to Raven Rock is via the Appalachian Trail from the north or south. The side trail to Raven Rock does not have a sign but there are blue blazes on the trees heading to the lookout. It is easy to miss so keep your eyes open!
Camping and open fires are only permitted at established camping areas and with existing fire rings.
The closest camping area is the Devils Racecourse Shelter area approx 1 mile north of Raven Rock on the Appalachian Trail, but it is well worth the extra walk to see the Devils Racecourse. The Devils Racecourse is large boulder field in the middle of the woods and incredible to explore. The shelter has a spring and a privy. *****UPDATE ********
You might want to update the page, as they have put in the Raven Rock Shelter within 0.1 mile of where the turn-off is for Devils Racecourse. It's actually located on the west side of the trail, as opposed to the Devils Racecourse shelter, which is on the east. The Devils Racecourse shelter is still there but I don't think it's going to get much use with a brand new one up there that is much closer and in better condition.
