Big Run Falls at Cascade Park in New Castle, Pennsylvania is a small overlook walk to the Big Run Falls lookout point. Big Run Falls is a 20 to 25 foot waterfall located in the center of Cascade Park with a lookout point downstream. There's no way to hike down to the falls itself since the park discourages people swimming in the pool below, so this is less of a trail and more of an overlook.
To make more of a hike out of this trip, you can walk down the road/hill to the creek itself and then hike up along the side of the creek to the base of the falls - this would likely be a 1 mile out-and-back hike including getting down to the creek itself; however, the GPS data provided here just brings you to the overlook area.
History: Cascade Park is a former amusement park that ran from 1897 until the early 1980s. Shortly after its closure, the rides were removed and it was turned into a public space.
