Greenwell State Park stretches across 596 acres along the Patuxent River in St. Mary’s County, Maryland, offering a quieter alternative to the state’s more heavily visited parks. The property once belonged to the Greenwell family, whose legacy lives on through a park that emphasizes accessibility — many of its trails and facilities were designed to welcome visitors with disabilities, a feature that sets it apart from most parks in the region.

The riverfront location is the main draw. A sandy beach along the Patuxent provides swimming and sunbathing in summer, while the river itself attracts anglers targeting striped bass, perch, and catfish. Horseback riding is permitted on designated trails, and equestrians will find the relatively flat terrain through mixed hardwood forests and open meadows easy to navigate. Hikers and mountain bikers share a network of trails that wind past historic farm buildings and down to the waterfront, with most routes staying under two miles — ideal for families with younger kids.

Birdwatchers should bring binoculars. The park’s mix of forest, field, and riparian habitat draws ospreys, bald eagles, and a strong variety of songbirds, particularly during spring and fall migration. Winter visitors can catch glimpses of waterfowl congregating on the river.

The best time to visit is late spring through early fall, when the beach and water activities are in full swing. Note that the park is a day-use facility, so plan your camping elsewhere — nearby Point Lookout State Park is a solid option for overnight stays.
