Rosaryville State Park: A Moderate 9.4 Mile Hike

Rosaryville State Park: A Moderate 9.4 Mile Hike

SEE IMPORTANT INFORMATION ON REGISTRATION UNDER "NOTES."

Rosaryville State Park, spanning 982 acres in Upper Marlboro, Maryland, was established in 1976 following the state’s acquisition of the historic 341-acre Mt. Airy Plantation and its 18th-century Mount Airy Mansion. Originally operated as a distinguished Calvert family thoroughbred breeding farm, the property later served as a private country inn before becoming a public park renowned for its scenic trails and landmark mansion.

The park’s landscape features a diverse mix of hardwood forests and wetlands, with designated areas for preserving native plant species. The trails are unpaved, offering well-maintained, single-width paths winding through the woods. Hikers should be mindful of natural obstacles such as roots and branches, as well as challenging elevation changes and creek crossings without bridges. On this hike, we will traverse a 10-mile “Perimeter Trail.”

A leashed, well-trained Fido is welcome on this hike

Bring a lunch to enjoy along the way.
