Well known to mountain bikers, Rosaryville State Park offers a great opportunity to leave the city behind and enjoy a much more serene environment.
The park is located about 20 miles southeast of the District in Upper Marlboro, Maryland. We also know, albeit anecdotally, that the park tends to be much less traveled than other DC area favorites like C & O National Historic Park. So while we can't guarantee anything, if you are looking to beat the crowds Rosaryville could be a good option.
The park really only offers one trail, the Perimeter Trail. The Perimeter Trail is about 9 miles in length, and features plentiful switchbacks with many minor in length, but sometimes steep hills.
White posts with arrows and other useful information are posted along the path to keep you on track.
A couple of other notes specific to mountain bikers. The park asks that you avoid tearing up the trail by not biking when the ground is muddy. Additionally, bikers need to mind the blind curve signs because folks tend to bike in both directions.
Hikers should also enjoy the trail. At 9 miles, the hike should take most people 3-4 hours to walk. Leashed dogs are permitted.
In addition to the Perimeter Trail, the park also features the Mount Airy Mansion, which is popular for weddings. The park houses two pavillions, each accommodating 200 guests, that are available for rental. Visit the Rosaryville State Park website for more details.
