The main ridge at Maryland Heights has the ruins of Union Civil War forts, trenches, gunpowder magazines, and infantry encampments. With most of the circuit having informational signage describing the different ruins.
From the parking area at the train station cross the pedestrian bridge and stay left to the trailhead at the bottom of the steps. Start up the Combined Trail and pass the Naval Battery built in 1862, and first of the Union fortifications on Maryland Heights. At the next intersection, and informational sign, turn left uphill on the Stone Fort Trail as it very steeply ascends towards the ridge.
Once arriving at the ridge pass through the main fort area, then climb a set of log stairs to reach the main interior of the fort. This main section, and largest earthwork, was constructed in June of 1863. The main stone wall on the north of the fort was erected to protect it from northern attack.
From here the Stone Fort Trail will pass back to the south, with views of the Potomac River to the east through the trees. The trail will descend more steeply before ending at the intersection of the top section of the Combined Trail.
Turn left towards the overlook and in 150 yards turn right down the Overlook Trail. The main overlook for Harpers Ferry is in 0.3 miles.
Return to the Combined Trail, then follow it past the two trailheads for the Stone Fort Trail as it descends back down to Sandyhook Rd.
