In the quiet countryside of southwestern Wisconsin, an eerie phenomenon continues to baffle and delight travelers. Just outside the small town of Shullsburg lies what locals call “Gravity Hill”—a spot on County Road U where cars appear to roll uphill when placed in neutral. It’s a curious sight, and while it may seem like magic, the explanation is far more grounded in science.
The Phenomenon
To witness the illusion for yourself, drive about 1.5 miles south of Shullsburg on County Road U. Just after passing Rennick Road, you’ll come across a point marked “GH” on the pavement. This is the legendary Gravity Hill. Here, motorists often stop their vehicles, shift into neutral, and are stunned to see their cars slowly begin to move—seemingly uphill.
The sensation is disorienting, with even seasoned drivers momentarily questioning the laws of physics. Videos shared by curious tourists and local enthusiasts show cars drifting backward against what appears to be an uphill incline. But what’s really going on here?
The Science Behind the Mystery
Despite the mystical experience, there’s no violation of Newton’s laws. What’s happening on Gravity Hill is a well-documented optical illusion. According to experts and scientific observations, the slope of the road is actually downhill—but your brain doesn’t interpret it that way.
The illusion is caused by the surrounding landscape. Without a clear view of the horizon, the alignment of trees, fence lines, and elevation changes trick the eyes and mind into misjudging the slope. The background may appear level or tilted in a way that makes a downhill road look like it’s going uphill.
This visual confusion is a classic example of a gravity hill, a phenomenon found in various places across the globe. Other examples exist in Pennsylvania, California, and even in parts of Canada and Australia. But Wisconsin’s version, nestled among farm fields and rolling hills, offers a uniquely rural charm.
A Local Curiosity and Tourism Gem
The town of Shullsburg, with a population of just over 1,200, embraces the mystery. Local businesses occasionally reference Gravity Hill in their marketing, and tourism organizations have used it to draw visitors to Lafayette County.
For visitors seeking a quirky roadside attraction, Gravity Hill offers a fun and free detour. It’s best to visit during daylight hours and in good weather, as the road is a regular county route with no special safety measures in place.
Wisconsin’s Department of Transportation (WisDOT) reminds travelers to always use caution when stopping on public roads. If you plan to try the experience, turn on your hazard lights, check for traffic, and make sure you’re not obstructing the roadway. More information on Wisconsin road safety guidelines can be found on the WisDOT official website.
What Locals Say
“I grew up in Shullsburg, and we used to come out here all the time as teenagers,” said local resident Rebecca Meyer. “We’d put the car in neutral, scream like we were in a haunted house, and roll uphill. Of course, we know now it’s just an illusion, but it’s still fun.”
Some even recall myths and folklore surrounding the spot. Tales of ghostly children pushing cars, magnetic anomalies, and ancient spirits are common—but entirely unfounded. Gravity Hill remains an example of how natural geography can play tricks on human perception.
