You will be able to reach Elephanta caves from Mumbai within 15 minutes as opposed to the 60-minute journey that you currently need to take. A ferry ride from the gateway of India is the only transport option. Come 2022, and you will have an 8-km long ropeway from Mumbai to the caves. It will be constructed over the Arabian sea and will be the first such ropeway over an ocean, in the country. 30 cable cars will operate on the route.
