The county’s western border is formed by the Potomac River, and part of the eastern border is the Patuxent River. Adjoining counties are Prince George’s to the north; Calvert and St. Mary’s to the east; and parts of Virginia to the west and south, across the Potomac River.
Charles County’s Potomac River shore is much indented, with many tidal tributaries flowing into the Potomac River through bays and inlets. Some of the Potomac shore is characterized by cliffs and bluffs, while other areas are low-lying marshland or sandy beach. The county’s waters range from freshwater in the interior tidal waterways to brackish near the Potomac. Much of the interior is hilly and forested, with interspersed agricultural fields. Wetlands are abundant. There are hidden residential estates as well as typical suburban developments, but much of the county is surprisingly undeveloped, considering its proximity to Washington, DC. It is notable that four of the National Audubon Society’s Important Bird Areas are located in Charles County, an indication of the richness of the habitat there.
US Route 301 (Crain Highway) is the main north-south corridor, and the Harry W. Nice Memorial Bridge connects Charles County to Virginia, carrying Route 301 over the Potomac. A large number of state routes criss-cross the county to reach the innumerable peninsulas and necks.
