Kumbh Mela, the once in twelve year event that witnesses the largest gathering of people in one place on earth, is back in 2010. The venue is Hardwar, said to be one of the holiest places in earth.
Besides the pilgrims who come to be blessed by bathing in the river, the event attracts large number of travellers and photographers who come to witness the event. The mela begins on the 14th Junuary 2010 and goes on for more than 3 months.
