About Columbia Island Marina
Columbia Island Marina on the Potomac River has a home for your powerboat. We provide services for boaters seeking year-round slips as well as for those looking for the perfect place to enter the Potomac for fishing or cruising by the monuments.
Conveniently located in the beautiful Lyndon B. Johnson Memorial Grove on the Pentagon Lagoon on the Virginia side of the river, the marina is just one and a half miles north of Ronald Reagan Washington National Airport on the George Washington Memorial Parkway in metropolitan Washington, DC.
