Patapsco Valley State Park is pet-friendly. You are welcome to bring Fido with you to enjoy the 32 miles of recreational land along the banks of Patapsco River. There are over 200 miles of trails around the park that can be explored by dogs and their owners, with 70 of those miles identified as maintained trails. Dogs are allowed to join their owners around most of the park, but they are prohibited in the campground of the Hilton Area of Patapsco Valley State Park and in the Pickall Area. If you're bringing Fido with you, don't forget to keep them on a leash and to clean up any mess that they leave behind. Patapsco Valley State Park is open every day of the week from 9am until sunset.
