About Calvert County

Calvert County is a busy place, which is not surprising considering it is part of the Washington, DC, metro area. It is close to major highways and airports, businesses large and small, as well as the seat of the federal government.

The county itself is a peninsula on Chesapeake Bay’s western shoreline that consists of 213 square miles, which makes it the smallest county in the state. This county offers residents and visitors a bountiful selection of cultural events and recreational activities.
