General Description:

982 acre Rosaryville State Park is dominated by "edge" habitat where fields and forest meet. Dense vegetation found along the edges creates ideal habitat for a wide diversity of wildlife. The larger mammals, such as white-tailed deer, raccoons and skunk are often seen foraging in the fields and along the forest border.

10 miles of trails ideal for mountain biking are available for day use. The trails wind through a canopy mixed mature hardwood forest and open fields, offering interesting views of forested wetlands. The park is home to the historic Mount Airy Mansion, which provides an elegant setting available to the public for special occasions.


The Trails:

The trails are mostly moderate, tight and twisty singletrack requiring moderate climbs, several steep climbs and descents and technical sections. Beginners can hike-a-bike around the technical sections.

Detailed trail maps are available at the Mt. Airy mansion or at Cedarville State Park or on the DNR web site (see for more information below).

Perimeter Trail: 7.5 miles (moderate to advanced)
Developed and designed in cooperation with Maryland's Department of Natural Resources, IMBA's former trail crew member Rich Edwards, Mid-Atlantic Off Road Enthusiasts (MORE) and the Rosaryville Conservancy. The trail circumnavigates the park, passing through mostly woods, providing cool shade during the hot summer months on a tight, twisty singletrack route with some short steep hills.

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.

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.


Note: Trails are extremely vulnerable to damage during and following rain and many areas remain wet muddy (mud sticks to anything). Allow at least 24-48 hours for trails to dry after significant rain or call the Southern Region Headquarters office for updated trail conditions. Use existing roads and paths and avoid establishing new trails or taking shortcuts.



Historical Note:

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 when he came from England around 1660. 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.
