Elephanta Caves: Island of Elephanta is the famous abode of Lord Shiva and an incarnation of Hindu cave culture. It consists of seven caves on an island with temples from Hindu mythology, which bears unique evidence to a civilization that has disappeared.
These archaeological remains reveal evidence of occupation from as early as the 2nd century BC. Visiting the caves will also give you the site of the famous Gateway of India. Travelling in a Toy Train or a Ferry will give you a whole new encounter.
