Ladakh region in India is as famous for its astounding beauty as its many mysteries. One of the mysterious locations that has always baffled travellers here is the Magnetic Hill, which lies 30 km from the capital city of Leh. A stretch of the solitary road defies gravity – if the engine of a vehicle is turned off, it will slowly start moving uphill at a speed of 10-20 km/hr. Many locals here claim that the magnetic pull is due to supernatural factors. Scientists however claim that the real cause is optical illusion – what appears to be uphill is actually a downhill, and is not visible to the human eye.
