Maryland's Appalachian region offers natural splendor, outdoor adventure, and opportunities to explore the region's rich heritage a few miles off Interstate 70. Maryland byways such as the Historic National Road and the Journey Through Hallowed Ground lead travelers through rolling countryside, covered bridges, vineyards, orchards, small towns, historic inns, antique shops, restaurants, and distinctive shopping areas. Wilderness recreation is close at hand, with camping, hiking, kayaking, fishing, hunting, rafting, and rock climbing. The C&O Canal provides almost 185 miles of scenic biking and hiking and connects in Cumberland to the Allegheny Highlands Trail, while the wheelchair accessible Boardwalk Trail leads to 78-foot Cunningham Falls. In Maryland, the Appalachian National Scenic Trail follows the ridgeline of South Mountain for 40 miles past the War Correspondents Memorial Arch and Frederick County's Washington Monument, and a day hike to Annapolis Rock in South Mountain State Park offers views of the Cumberland Valley and attracts rock climbers. Where the Shenandoah and Potomac rivers meet at Harpers Ferry National Historical Park, fast water draws rafters and kayakers, and on Antietam Creek local guide services offer whitewater, paddling, and tubing trips. Access to the Potomac River is available at towns such as White's Ferry, Point of Rocks, and Brunswick, and canoes and kayaks can launch at locks along the C&O Canal. The area's waterways also attract anglers, with Big Hunting Creek and the Potomac River offering trout, bass, bluegill, and catfish. Visitors can also golf, picnic along the Frederick Wine Trail, tour Washington County's stone bridges, and explore historic districts. Catoctin Mountain Park offers camping along the Journey Through Hallowed Ground, including Camp Misty Mount, whose cabins were built by the Works Progress Administration in the 1930's, while Greenbrier and Cunningham Falls state parks and private campgrounds offer swimming beaches, fishing, boating, and camping.
