A photo of the front of the mansion Rosaryville State Park is a 982-acre, day-use park with approximately 10 miles of trails ideal for birding, horseback riding, hiking and mountain biking. The trails wind through mixed hardwood forest and field with interesting views of forested wetlands. The park is also home to the historic Mount Airy Mansion, which provides an elegant setting available to the public for special occasions.

Mount Airy Mansion


The original Mount Airy Mansion was built in approximately 1660 as a hunting lodge by Charles Calvert, the Third Lord of Baltimore. The dwelling then consisted of one 50-foot room with fireplaces on each end. During the 1750s, the main section of the mansion was added, creating the grand building seen today.

Seven U.S. Presidents have visted the Mount Airy Mansion, including George Washington, who attended his stepson's wedding in the mansion in 1774. President Franklin Delano Roosevelt was also known to have visited the mansion as a guest of Miss Patterson, the Times-Herald newspaper magnate and owner of the Mansion in 1931. Miss Patterson improved the property, adding a swimming pool, tennis court, guest cottages and a large greenhouse. In 1972, the land of Mount Airy was willed to the Maryland Department of Natural Resources.

The Mount Airy Mansion is available to the public by reservation for special events and occasions. Pineapple Alley Catering, Inc. is the manager and exclusive caterer for Mount Airy Mansion. For reservations, please call 301-856-9656 or visit www.mountairymansion.org

The entrance road to the mansion is open to vehicular access solely by parties renting the mansion.

Nature Appreciation


Rosaryville State Park features rolling fields and a mixed hardwood forest of sassafras, oak and black locust commonly found in Southern Maryland. The park's landscape is dominated by edge habitat where these fields and forest converge. Dense vegetation found along these edges creates habitat for a wide diversity of wildlife. Birds, including field sparrows and brown thrashers, enjoy the cover and food provided by the field and forest edge. Moles, rabbits and mice attract birds of prey, such as the commonly seen red-tailed hawk, recognized by its large, broad wings and tail. Larger mammals, such as white-tailed deer, raccoons and skunk are also often seen foraging in the fields and along the forest's border. The American Lady butterfly, distinguished by its uneven brown, yellow and orange pattern is commonly seen in the park.

Trails


Please Play Safe!
Rosaryville State Park is a natural area with certain hazards, such as poison ivy, rocky and slippery trails and biting insects. Sturdy shoes and water are recommended when exploring these trails. Avoid riding when trails are wet or soft as hoof prints and bike tracks can damage the trails. Remember, you are responsible for having the necessary skills, knowledge and equipment for a safe and environmentally sensitive visit.

  • Perimeter Trail 7.5 miles - moderate to difficult
    This trail circumnavigates the park, providing hikers, cyclists and horseback riders with a tight, twisty, single-track route. The trail passes primarily through the woods, providing plenty of shade during hot summer months. The western section of this trail is mainly easy to moderate in difficulty. The trail in the eastern section has moderate to difficult terrain with more technical sections and frequent short hills that provide challenging climbs.

  • Tanager Point Overlook Trail 0.2 mile - easy
    This overlook got its name from the numerous scarlet tanagers that spend the summer in Rosaryville State Park. You can recognize the males from their brilliant scarlet red plumage. Female plumages are yellow underneath. This trail is not hardened and therefore does not comply with ADA access guidelines; however, it may be useable by some persons with disabilities due to its relatively level surface and short distance to the overlook.

  • Spur Trails no blazes
    There are a number of spur trails throughout the trail system that provide opportunities to shorten or lengthen the trail circuit. These spurs are not maintained, however, so caution is advised when using them.
