Watkins Mill State Park is a fascinating and serene place to visit. I was impressed by the well-preserved Watkins Woolen Mill, which is a National Historic Landmark and a state historic site. The mill offers guided tours that showcase the original machinery and the history of the Watkins family and their workers. The park also has a six-acre lake where you can swim, fish, or boat. The lake has a paved bicycle path around it, which is perfect for a leisurely ride or a walk. The park also has four hiking trails that offer views of the rolling farmland, the wooded hills, and the wildlife. The park has a campground with both basic and electric sites, as well as modern restrooms and hot showers. The park staff was friendly and helpful, and the park was easy to find and access. Watkins Mill State Park is a great place to learn about the past and enjoy the present. I highly recommend it to anyone looking for a historical and relaxing vacation.
