Every year the Indian town of Pushkar in Rajisthan holds a five day camel fair, one of the world's largest, which takes place by the banks of the Pushkar Lake. Groups of traders and herders set up camp in the dunes around Pushkar, bringing around 50,000 camels. The fair's main day is celebrated on full moon day, when the Hindu god Brahma was said to have emerged from the Lake. For this reason, people swim in its waters during the event.
