The Elephanta Caves are located just off Mumbai harbour in the Gharapuri Island also called Elephanta Island - a name given by the Portuguese when they ruled over this area. In 1987, the caves were designated a UNESCO World Heritage Site. Hewn out of solid rock, the Elephanta Caves date back to 600 AD. The caves attract many visitors who take an hour long ferry boat ride to reach from Gateway of India. The cave complex is a collection of rock-cut architecture with stone sculptures of Hindu Gods and Goddesses.
