Embark on a journey along the Appalachian Trail to discover the dramatic landscapes of High Rock and Raven Rock. This moderate 5.2-mile (8.4 km) hike, with its 872 feet (266 metres) of elevation gain, takes about 2 hours and 32 minutes to complete, offering a mix of shady woods, open clearings, and challenging rocky sections. You'll navigate boulder fields and stony steps, culminating in the expansive vistas from High Rock Overlook and the unique rock-lined amphitheater at Raven Rock. The trail provides a rewarding experience for those seeking a varied and scenic outing.
When planning your visit, be aware that the High Rock Overlook can get busy due to vehicle access, so starting early is advisable for a more serene experience. The terrain includes some very rocky areas where careful navigation and attention to the white blazes of the Appalachian Trail are essential. Spring brings beautiful mountain laurels, and fall offers vibrant foliage, making these seasons ideal for hiking.
This section of the Appalachian Trail is notable for containing the sharpest ascent in Maryland, gaining over 500 feet in just 0.4 miles, and also includes the highest point of the trail in the state at 1905 feet.

The Pen Mar High Rock Overlook via Appalachian Trail offers a taste of the iconic footpath's more rugged side, leading to dramatic panoramic views. This moderate 5.0-mile (8.0 km) hike, with 516 feet (157 metres) of elevation gain, takes about 2 hours and 20 minutes. You'll navigate through varied forested terrain, encountering rock formations and a notably steep, rocky final push to the High Rock Overlook, where the Cumberland Valley unfolds before you.
Your journey starts at Pen Mar Park, which provides convenient parking and its own initial scenic views.

While the overlook offers incredible vistas, be aware of the graffiti that is present there.

This section of the Appalachian Trail, stretching from Route 16 to Snowy Mountain Road, plunges you deep into Michaux State Forest, offering a quintessential "Rocksylvania" experience. You'll navigate a primarily rocky footpath through dense hardwoods, with the terrain demanding your full attention. The reward for your efforts comes with stunning panoramic views from spots like Buzzard Peak, making the 9.2-mile (14.8 km) hike, with its 1690 feet (515 metres) of elevation gain, feel truly earned over its estimated 4 hours and 27 minutes.
Planning your visit means preparing for a moderate but physically engaging hike. Trailhead access is convenient from both Route 16 and Snowy Mountain Road, though parking at either end can fill up quickly, so an early start is recommended. Be sure to wear sturdy hiking boots to handle the foot-bruising rocks, and consider bringing trekking poles for added stability on the uneven surfaces. Facilities like the Antietam Camping Area and Deer Lick Shelter offer convenient spots for a break.
Beyond the natural beauty, this segment of the Appalachian Trail is steeped in history. The area near Route 16 is close to the Monterey Pass Battlefield, a significant Civil War site, and parts of the Underground Railroad once ran along Mentzer Gap Road. This blend of challenging terrain, rewarding vistas, and historical context makes the route a standout choice for hikers looking for more than just a walk in the woods.
