A Lehigh Valley amusement park that began in 1884 as a fish hatchery and picnic grove on Cedar Creek. The roller-coaster era took hold in the 1920s, and steel arrived for good when Steel Force opened in 1997, then a mile-long out-and-back ride along the creek bottom. Wildwater Kingdom, the waterpark next door, opened in 1985. Most of the older oaks in the picnic groves predate the rides.
