Nadi is located on the western side of the main island of Viti Levu, Fiji. Along with sugar cane production, tourism is a mainstay of the local economy. With its large Indo-Fijian population, Nadi is a centre for Hinduism and Islam in Fiji. The downtown area is defined by the Nadi River and Viseisei village on the west side, and the beautiful Sri Siva Subramaniya temple on the east. It is the largest Hindu temple in the Southern hemisphere, and is a site for pilgrims. Muslims worship at the Nadi Mosque and the Ahmadiya Mosque.
