2.9 mi 860 ft gain moderate rocky

Dark Hollow Falls

Shenandoah's most-visited waterfall trail — a short steep descent to a 70-ft cascade. Strenuous on the return climb.

1.4 mi 440 ft gain moderate rocky

Whiteoak Canyon Falls

Down to the 86-ft Upper Falls, the headliner of six waterfalls on Whiteoak Run. Rocky and slick — ankle-twister terrain if you hurry. Reaching all six falls requires the full canyon descent (much longer, much more elevation).

Shenandoah's second-tallest peak (4,011 ft) via a short, family-friendly loop. Greenstone summit (ancient metamorphosed basalt) with panoramic Blue Ridge views. No dogs — Stony Man is on the NPS pet-prohibited list.

6.5 mi 1200 ft gain hard rocky

Loudoun Heights Loop

Harpers Ferry National Historical Park · WV

7 mi 1350 ft gain hard rocky

Bolivar Heights

Chesapeake & Ohio Canal National Historical Park · MD

Civil War battlefield ridge inside Harpers Ferry NHP — short mowed-grass and dirt loops through cannon-studded meadows with views toward the Shenandoah Valley. Quieter than the lower-town trails.

Paw Paw Tunnel

Patapsco Valley State Park · MD

The 3,118-ft canal tunnel cut through Green Ridge, with a steep ridge-top bypass trail you can loop. Through the tunnel itself is flat and easy, but the bypass adds the climb that makes this a moderate outing. Bring a headlamp — the tunnel is pitch black and takes ~20 minutes to walk through. Closures recur for restoration work, ice, and bat-related seasonal restrictions.

3.5 mi 300 ft gain moderate mixed

Cascade Falls

Patapsco Valley State Park · MD

Patapsco Valley — Daniels Area

Gunpowder Falls State Park · MD

Upstream gorge of the Patapsco with ruins of the old Daniels mill town. Standard riverside loop to the dam ruins; longer ridgetop connectors add a powerline-cut climb if you want a 4–5 mile day. Quieter than the Avalon area; bike-legal on designated trails only (yield to anglers along the river).

3 mi 350 ft gain moderate dirt

Crushed-limestone rail-trail heading west toward Frostburg — gently graded uphill the whole way (the GAP climbs ~1,270 ft from Cumberland to Frostburg, capped at the railroad's 1.75% grade). The C&O Canal towpath ends here too — Cumberland is the GAP/C&O junction.

5 mi 350 ft gain easy gravel

Rocky Gap State Park · MD

The final 11.5 miles of the C&O Canal towpath into Cumberland — Spring Gap (MP 173) to the western terminus at Canal Place (MP 184.5). Flat, shaded, riverside. Far quieter than the DC-end sections; you'll often have a mile of towpath to yourself.

11.5 mi 80 ft gain easy gravel
