The C&O Canal in Georgetown, Washington, D.C.
The Chesapeake and Ohio (C&O) Canal is one of the most intact and impressive survivals of the American canal-building era. The C&O Canal is unique in that it remains virtually unbroken and without substantial modification affecting its original character for its entire length of 185 miles. Today the park is a popular getaway for Washington residents. The towpath is popular with bikers and joggers.
