| A blue heron on the lookout for fish in the C&O Canal near Swains Lock, Potomac, Maryland. |
The southernmost point of the C&O begins in the Georgetown section of Washington, D.C. and snakes north and west within the state of Maryland until, 185 miles later, it ends at Cumberland, MD, near the Pennsylvania border.
We try to
get in at least three-plus miles of scenic exercise when we visit our daughter's
family in Potomac. Swains Lock – sixteen
miles north of D.C. – is a short drive away from her home, down a narrow,
serpentine access road.
