Just southeast of Solomons is the historic St. Mary's City, one of the very first British settlements in North America.
The chalk cliffs at Calvert Cliffs State Park, a few miles north of town, are a fun spot for fossil hunting. The park is very popular, and its public beach is usually picked over by noon; however, even casual visitors can expect to find common fossils. The park also offers an elaborate playground constructed from used tires and excellent wildlife spotting along its marsh.
To the north, in Lexington Park, you can visit the Patuxent River Naval Air Museum.
