For days before Gangaur, women and girls worship clay idols of Gauri at home, singing in the evenings and painting mehendi on each other's hands. On the main days, the idols are dressed in fresh finery and carried through the lanes towards the water, and the city follows behind.
The procession ends at Gangaur Ghat, named for this very ritual, while the Mewar Festival adds boats, music and fireworks over Lake Pichola. Find a spot along the ghats or on a nearby rooftop well before evening, because by sunset there is barely room to turn around.
