Bigfoot Rapids is a rapids ride in Ghost Town at Knott's Berry Farm. While it's not the best, it is also recommended. The minimum height to ride is 46 inches.
A basic tub-raft rapids ride, without a drop but with a few surprising waves and splash-backs along the way. The waterfall in the middle's gone, so some riders get away without getting too wet, while a few do end up soaked to the bone.
