Udupi in karnataka is known for housing the atmospheric Krishna Temple, built in 13th century. Thousands of Hindu pilgrims visit the temple throughout the year. Having surrounded by eight maths or monasteries, it observes a ritual activity which sees musicians playing at the gateway and elephants on hand for puja while pilgrims keep passing through it. Non-Hindus can also visit the temple. Men have to enter bare-chested. During the Udupi Paryaya festival, elaborate rituals are performed in the temple.
