Rosaryville State Park
Rosaryville State Park is a dog-friendly day-use park spanning 982 acres in Upper Marlboro, MD. The centerpiece of the park is the historic Mount Airy Mansion, which is the only area of the park that isn't pet friendly. There are numerous trails that are accessible to dogs and their owners, including some that are paved. Dogs are welcome on a leash as long as all mess is cleaned up after them. There is a park entrance fee, and Maryland State Park passes are accepted.
