We're going to be upfront with you on this one: reliable, published parking rates for Mumbai Metro stations are genuinely hard to find, and we're not going to invent numbers just to fill out a guide.
What we can confirm
Paid parking - for two-wheelers, four-wheelers, and bicycles - is available at Aarey JVLR and Sahar Road stations on Line 3, according to MMRC's own FAQ page. No per-hour or per-day rate figures are published there.
What we couldn't confirm
Whether parking exists at other stations across Lines 1, 2A, and 7, and what any of the rates actually are. If you're planning to park-and-ride, your best bet is to call the MMRC/MMMOCL passenger helpline (1800220220 / 1800220221) before you go, or simply check on arrival.
Bottom line
Parking is confirmed at Aarey JVLR and Sahar Road on Line 3. Beyond that, don't trust a specific rate you see quoted online - including anywhere else you might read one - without checking with MMRC directly first.
