Kumbh Mela, Prayagraj
The largest peaceful gathering on earth draws between 40 and 50 million people over its full run, and the Maha Kumbh cycle, which falls every twelve years at Prayagraj, pulls even more. The Sangam, where the Ganga, Yamuna, and the invisible Saraswati converge, is the bathing point, and the Shahi Snan dates (the royal bathing days) are when the crowds peak to numbers that make ordinary crowd management meaningless.
