The C&O Canal National Historic Park preserves the remains of the historic Chesapeake and Ohio Canal as well as valuable wild spaces along the Potomac River shoreline from Washington, D.C., to Cumberland, MD. The Canal’s entire 185-mile long towpath is restored, open to hikers and bikers year ‘round and is accessible from many points in Frederick County including the Mouth of Monocacy Road near Dickerson, Nolands Ferry, Point of Rocks, Lander and Brunswick. The C&O Canal National Historic Park Visitor's Center in Brunswick shares the building with the Brunswick Railroad Museum. Mule-drawn canal boat rides are offered at Great Falls, MD, and in Georgetown, D.C., Apr-Oct, Wed-Sun 11am, 1:30 & 3pm. Call 301-767-3714 or visit the website.
