Dogs are welcome to join their owners at Cedarville State Forest in Brandywine, Maryland. This area was previously the winter camping ground of Piscataway Indian Tribe. The headwaters of the Zekiah Swamp are located in the park, extending through Charles County for 20 miles, and finally emptying into the Wicomico River. There are a number of fields around the swamp that can be explored by dogs and their owners, and who knows, you may find the burial ground that is rumored to be in the area. Remember to keep Fido on a leash under six feet for the duration of their stay. Dogs are allowed in all the day use areas and can even camp in the campground with their owners too. You'll also find a number of picnic spots dotted around the park. Cedarville State Forest is open every day of the week from sunrise to sunset.
