· Chesapeake & Ohio Canal National Historical Park
Washington County's 78.8-mile portion of the 184.5-mile canal from Cumberland, Md., to Georgetown in Washington, D.C., is one of the canal's most interesting and attractive segments.
Williamsport, which has the second largest aqueduct along the canal, is the midpoint between Georgetown and Cumberland at mile 99.
The Conococheague Creek aqueduct was damaged by repeated floods.
The canal towpath has views of the Potomac River, Sharpsburg, Williamsport, Four Locks and Hancock. Williamsport Visitor Center, Cushwa Basin and Conococheague Creek Aqueduct are the most extensive groupings of original canal structures along the canal.
C&O Canal Days are held the fourth weekend in August, undertaken cooperatively with the town of Williamsport.
Bicyclists and horseback riders are allowed on the canal towpath.

· Greenbrier State Park
The park east of Hagerstown off U.S. 40 has nine trails, not including the Appalachian Trail.
The 0.6-mile Bartman Hill Trail provides a cleared path between the park's visitors center and the Appalachian Trail. The trail is steep, so the climb might be strenuous.
The Big Red Trail is a strenuous 4.5-mile loop, but it has long sections that are relatively flat. The average person probably can hike the loop in 2 1/2 hours.
Mountain bikes are allowed on most trails, but not on the Bartman Hill Trail. Horses also are allowed, but not motorized vehicles. Dogs are not allowed in the developed parts of the park and cannot come in the front entrance. Dogs that are kept on 6-foot leashes may enter the park from parking areas on the park's boundary or back area.
Maps of the trails and trail rules are available at the booth entering the park.
Some trails are in public hunting areas, so people hiking in the fall should wear bright colors and be aware of hunters. The hunters access the area from the trails, but hunt in the woods.
The park also offers boating, camping, fishing and swimming.
The park charges a nominal service fee, the amount of which depends on the time of year.
For information, call 301-791-4767 or go to www.dnr.state.md.us/publiclands.
