A must-do hike for any avid hiker in the DC area. Situated at the confluence of the Potomac and Shenandoah Rivers, Harpers Ferry, WV is a picturesque 19th-century town ripe with Civil War and industrial history. Our route today provides spectacular views of the village and the rivers. The main ridge at Maryland Heights features ruins of Union forts, trenches, gunpowder magazines, a naval (yes, naval) battery, and infantry encampments. But don't let the visual attractions distract you; this strenuous 7.5-mile hike includes 1700 feet of often-steep elevation gain. Some previous Adventuring excursions to Maryland Heights have had to be aborted before we got to the summit because several of our hikers were just not ready for all the exertion they needed to put out. But for those able to make the climb, the rewards will be stupendous. Bring beverages, lunch, bug spray, sturdy boots and about $15 for transportation, admission and trip fees. Meet at 9 a.m. at the Grosvenor-Strathmore Metro Station.
