American Plunge is a flume ride in Hugo's Hill Street at Silver Dollar City. While it's not the best, it is also recommended. The minimum height to ride is 34 inches.
The American Plunge is an Arrow log flume with a few animatronic set pieces and a long, dark tunnel along the way (the tunnel used to be nicely themed, now, sadly, it is just a dark tunnel). The finale is the requisite 50-foot plunge to a splashdown.
