Ricketts Glen State Park is one of the state’s most picturesque locales. Featuring more than 13,000 acres, this impressive state park in Pennsylvania’s Columbia, Luzerne and Sullivan counties is home to the Glens Natural Area, a National Natural Landmark. It also offers 26 miles of hiking trails that take you through centuries-old forests and around stunning rock formations. If you only have time to trek one of the park’s 11 trails, travelers recommend choosing the Falls Trail. This 7.2-mile loop travels past 21 of the park’s 22 free-falling waterfalls, including Ganoga Falls (Ricketts Glen’s tallest waterfall).
