This is the Sangam, where Hindu pilgrims bathe in the Ganges river, at the Kumbh Mela 2013 festival near Allahabad (India).
I took this photo in the evening, where few people were bathing.
The wooden fence in the water and the small boats near the fence are for safety, as most of the Hindu pilgrims can't swim!
The Triveni Sangam is the confluence of the Yamuna and the Ganga (Ganges) rivers, and this is the holiest place to take the ritual baths during the Kumbh Mela.
Kumbh Mela is the largest festival on Earth, taking place once every 12 years, with more than 50 million Hindu pilgrims gathering to pray and bathe in the holy Ganges river.
