The name of the hill in County Louth where the car travels uphill is Gravity Hill, from Dundalk travel North on the M1, then take the Ravensdale turn off (right) sign posted, drive to the T-Junction take a right then drive about 3 kilometres towards Carlingford take a left turn for Omeath, again sign posted, this is a steep climb as you reach the brow the road drops back down, this is it. Drive to the bottom and turn the car around, switch off the engine and the car will go up the hill on its own, it picks up speed so keep your hands on the wheel, enjoy.
