Magnetic Hill is basically an optical illusion in which a slight downhill appears to be an uphill slope. The alignment of the road with the slope of the background can give the illusion that cars are able to drift upwards. The most important factor contributing to the illusion is a completely or mostly obstructed horizon; without a horizon, judging the slope of a surface is difficult as a reliable reference is missing. Quad Bike Advetures are available nearby.
