Log flumes are amusement rides consisting of a water flume and (artificial) hollow logs or boats. Passengers sit in the logs, which are propelled along the flume by the flow of water.

A log flume is a watertight flume constructed to transport lumber and logs down mountainous terrain using flowing water. Flumes replaced horse- or oxen-drawn carriages on dangerous mountain trails in the late 19th century. Logging operations preferred flumes whenever a reliable source of water was available. Flumes were cheaper to build and operate than logging railroads. They could span long distances across chasms with more lightweight trestles.
