This otherwise unremarkable slope in the road south of the town of Cabral has long been the subject of intense debate. Is it a freak magnetic phenomenon or optical illusion? Park your vehicle in neutral and watch as it moves uphill, then write us and tell us what you think. Trying to figure out is it or isn’t it is said to have inspired visitors to the site to go to great lengths for an explanation. Stanch believers claim magnetically charged ore in the earth causes the phenomenon, but a scientific survey said vehicles only appear to move uphill due to an eye-fooling cut in the gradient.

Driving Directions: Follow Carretera Polo south of Cabral about 10 miles. The mysterious spot is marked by a billboard north of the pueblo of Polo.
