It is 3.2 kms approx. Normally in Mumbai, you need not ask for fare amount before boarding, you just have to tell the destination, board the rickshaw and pay as per meter at the end of journey. (Approx 11-12 rs per KM) for rickshaw and approax 15 km per KM in non-ac black & yellow taxi.
But Outsiders dont know of this fact and commit the mistake of asking fare before boarding (Kitna Loge bhaiyya??), and the rickshaw wala comes to know that you are not from Mumbai. Then they quote 3-4 times the fare as per meter.
If...
more... you are not lucky enough to find a rickshaw who agrees to charge as per meter, you should not give more than 50-55 Rs from Kurla Stn to LTT via SCLR.
