Old Mill (ride)

An old mill is a type of amusement park ride with unaccompanied boats floated on guideways through dark tunnels. These themed dark rides originated in the late 19th century and are known by a variety of names, including tunnel of love and river cave. While generally considered a gentle ride, a variation that ends with a climatic splashdown, similar to the modern-day log flume, is known as a mill chute.

In its earliest incarnations, riders were taken by two-passenger boats through dark passages. There were two major themes: a relaxing romantic ride encouraging the couple to cuddle, or a spooky horror ride encouraging the couple to cling to one another. The darkness provided a degree of privacy and the frightening scenes offered a socially acceptable excuse for the physical contact at a time when public affection or even holding hands was considered inappropriate.

With the development of other socially acceptable opportunities and less stigma for unmarried couples to engage in physical contact, these rides became less popular and were either re-themed into children's attractions or torn down completely.

Riders travel slowly on themed boats along an artificial river that meanders through decorated caves and tunnels featuring different themed scenes of lighting, sounds, props, animatronics, or other visual effects. The boats drift along on a gentle current, typically generated by a paddle wheel. This type of amusement ride became relatively common at amusement parks across the UK and the USA in the mid-20th century. The concept of the river cave is also very similar to those of the early scenic railways in that they attempt to be both educational and entertaining.

Once a popular feature of many amusement parks, river caves are now relatively rare and can be found in only a few locations, mainly in the UK and United States. Despite their popularity in the early to mid-20th century, the shift in focus to the thrill ride in the latter half of the 20th century onwards and the sheer age of the design and mechanics of these rides means that many have been dismantled and sold or destroyed altogether.

The ride's name stems from the fact that most were themed around subterranean caverns, with styrofoam stalagmites and stalactites housing detailed displays from around the world, through time and from myth and legend.
