Chapman State Park
Chapman State Park is pet-friendly. The area is made up of mature forests and rare plants that hark back to days of old alongside the banks of Potomac River. There are a number of trails for dogs and their owners around the park, including the Potomac River Trail that joins Chapman’s Landing Road to the Potomac River; Marsh Trail that meanders through bottomland woods along the Potomac shoreline; and Coastal Woodlands Trail that makes a loop around gravel forest and a coastal oak forest. If you're planning on bringing Fido with you, make sure they're on a leash under six feet and you clean up any mess after them. Chapman State Park is open every day of the week from sunrise to sunset. Visit Website
