Kumbh Mela or Kumbha Mela is a mass Hindu pilgrimage of faith in which Hindus gather to bathe in a sacred or holy river. Traditionally, four fairs are widely recognized as the Kumbh Melas: the Prayagraj Kumbh Mela, Haridwar Kumbh Mela, the Nashik-Trimbakeshwar Simhastha, and Ujjain Simhastha.
In the Hindu religion, the festival of Maha Kumbh is celebrated every 12 years on the banks of one of the holiest rivers - Ganga in Haridwar, Kshipra in Ujjain, the Godavari in Nasik and Sangam in Allahabad where Ganga, Yamuna, and Saraswati meet.
