Kumbh Mela drew about 660 million people in 2025, making it the largest gathering on Earth

the gist

Kumbh Mela is a Hindu pilgrimage held every four or twelve years at four river sites: Prayagraj, Haridwar, Nashik and Ujjain. Its timing follows the positions of Jupiter, the Sun and the Moon in the Hindu calendar, and devotees bathe in the rivers to cleanse sins. About 660 million people attended in 2025, up from about 240 million in 2019, which makes it the largest gathering in the world. It has been on UNESCO's list of intangible cultural heritage since 2017.

so what

Kumbh Mela is one of the few human gatherings large enough to be visible from space, and it shows how a religious tradition can organise a temporary city of millions. Its scale raises real logistics challenges for crowds, health and infrastructure, which the organisers have to manage each cycle.
