About Haridwar :

Haridwar or Hardwar is regarded as one of the seven holiest places (Sapta Puri) to Hindus. According to the Samudra manthan, Haridwar along with Ujjain, Nashik and Prayag (Allahabad) is one of four sites where drops of Amrit, the elixir of immortality, accidentally spilled over from the pitcher while being carried by the celestial bird Garuda. This is manifested in the Kumbha Mela, which is celebrated every 12 years in Haridwar. During the Haridwar Kumbh Mela, millions of pilgrims, devotees, and tourists congregate in Haridwar to perform ritualistic bathing on the banks of the river Ganges to wash away their sins to attain Moksha. Brahma Kund, the spot where the Amrit fell, is located at Har ki Pauri (literally, "footsteps of the Lord") and is considered to be the most sacred ghat of Haridwar.
