Mumbai Trip Planner: Visa and Transport
Most Mumbai guides open with the Gateway of India. That’s backwards: the thing that actually decides whether you see it is the e-Visa application, and it needs sorting weeks before you touch a single sight. Get the visa right, dodge the June-September monsoon, and learn the three pieces of transport infrastructure that opened in the past two years, the Atal Setu sea bridge, the new Navi Mumbai airport and Metro Aqua Line 3, and the trip runs itself. Skip any of that and you’ll spend day one solving a problem this page answers in five minutes.
| Essentials | Detail |
|---|---|
| Visa | Almost everyone needs one; apply for the e-Visa at indianvisaonline.gov.in weeks before you book flights |
| Best months | October to February, cool and dry; June-September is the monsoon, not a footnote you can plan around |
| Days needed | 2 covers South Mumbai’s core; 4-7 once a day trip and the outer neighbourhoods go in, see the itineraries below |
| Getting in | BOM (Chhatrapati Shivaji Maharaj International) or the newer Navi Mumbai International Airport, open since December 2025, check which one your flight actually lands at |
| Money | Indian Rupee (Rs); UPI QR codes work at street stalls same as restaurants, carry some cash regardless |
| Booking warning | The Elephanta ferry and CSMVS museum both close Mondays, and Elephanta sailings suspend outright in rough monsoon weather |
Sort a Colaba or Bandra hotel early too. Rooms near the Gateway sell out around festival weekends and long weekends, so check Mumbai and Colaba hotel rates on Booking.com before you lock in flights, not after.
Do you need a visa for Mumbai?
Yes, almost certainly. Most nationalities need an Indian visa, and the e-Visa (eTV) is the practical route for most US, UK, EU and Australian leisure trips. Apply only at indianvisaonline.gov.in : the portal itself warns that no agent is authorised to charge extra facilitation fees, which is your cue that the copycat sites ranking above it in search results are exactly the trap they look like.
Budget real lead time, this is rarely a same-day approval, and file a separate e-Arrival Card online within 72 hours of arrival; it isn’t part of the visa and gets missed. A passport valid at least six months beyond your arrival date with two blank pages is the commonly required minimum, though it’s worth confirming against your specific nationality and visa type before flights get booked. Visa-on-arrival exists only for a narrow set of nationalities, Japan, South Korea and the UAE among them, so don’t count on it as a general fallback.
When should you go to Mumbai?
October through February, full stop. That window is cool, dry, and the one every source agrees on. June through September is the monsoon, and it isn’t a light-rain inconvenience: expect real flooding, waterlogging, disrupted suburban trains, and Elephanta and other ferry services suspending outright in rough weather. March to May runs hot and humid, tolerable but the least comfortable non-monsoon stretch.
If your dates land near mid-to-late September 2026, check the calendar for Ganesh Chaturthi first; Mumbai’s biggest festival brings huge crowds and processions, particularly around Chowpatty, and it moves your hotel and transport planning around it whether you intended to attend or not.
Mumbai’s new transport layer, and one old rule that still trips people up
Three genuinely new pieces of infrastructure changed how a Mumbai trip works, and plenty of older guides still don’t mention any of them. The Atal Setu, a roughly 22km sea bridge that opened in January 2024, links Sewri to Nhava Sheva and matters most if your route or your airport runs through Navi Mumbai. The Navi Mumbai International Airport (NMIA) itself began commercial flights in late December 2025, a genuine second option to the older BOM airport depending on your carrier, so check your booking confirmation rather than assuming. Metro Aqua Line 3, the city’s first underground line, has run end-to-end since October 2025, connecting Cuffe Parade to the Bandra-Kurla Complex area, useful if your hotel or plans sit anywhere near BKC.
The suburban rail network, “the locals,” is the actual backbone of the city, carrying an enormous daily load and running dangerously crowded at peak hours; if you ride it, avoid roughly 8 to 11am and 5 to 9pm unless you have to travel then, and use the women-only compartments if that applies to you. One older rule still catches visitors out: auto-rickshaws are not allowed in the island city, roughly the area south of Bandra and Sion, so budget for a black-and-yellow kaali-peeli taxi or an Uber/Ola ride in South Mumbai instead of assuming an auto will show up. Both taxis and autos run freely once you’re north of that line.
Money in Mumbai: INR, UPI and what things actually cost
Everything is priced in Indian Rupees (Rs). UPI digital payment is genuinely ubiquitous, even small street stalls display a QR code, and cards are accepted at hotels and mid-to-upper restaurants, but carry some cash for stalls, autos and small purchases where card readers don’t exist. Mumbai is widely called India’s most expensive city, but that’s relative: street food runs a few hundred rupees, a sit-down mid-range restaurant meal lands somewhere between a few hundred and upwards of Rs 1,000, and it’s only luxury dining and five-star stays that price like any other global city.
Is Mumbai safe for tourists?
Yes, for a megacity, with the ordinary care any megacity this size requires. Violent crime against visitors is genuinely rare; the real risks are pickpocketing in crowds and packed trains, traffic (don’t attempt to drive yourself), air pollution, and monsoon-season flooding disrupting whatever you had planned that day. A practical women’s-safety note applies here as it does across India generally: registered taxis or ride-hailing after dark, and avoiding empty train compartments late at night, rather than anything specific to Mumbai.
Tap water is not safe to drink anywhere in the city, bottled or sealed only, and ordinary street-food hygiene sense applies, busy stalls with high turnover and food cooked fresh in front of you. Don’t lock in a specific advisory level from an old blog post; the UK’s FCDO advisory for India is worth checking directly since it updates far more often than any guide, and as of this writing it doesn’t flag Mumbai or Maharashtra state at all, restricting its warnings to the India-Pakistan border area, Jammu and Kashmir, and Manipur.
The sights, once the logistics are sorted
Mumbai, formerly Bombay until the Government of India’s November 1995 rename, holds three UNESCO World Heritage listings, CSMT the railway terminus, the Elephanta Caves across the harbour, and the Victorian Gothic and Art Deco Ensembles that run from the Fort precinct along Marine Drive, confirmed by incredibleindia.gov.in . None of that is the point of this page; what matters here is getting to them. CSMT sits in South Mumbai and doubles as a working station, no ticket required to view it from outside. The Elephanta ferry leaves from the Gateway of India, runs roughly an hour each way, and is closed Mondays and grounded outright in bad monsoon weather, so check current Elephanta Caves tour availability on GetYourGuide rather than showing up at the dock and hoping. A Dharavi tour is worth booking through an established, locally reinvesting operator, browse Dharavi tours on Viator and check what the company says about where the money goes before handing any over.
Bollywood, Hindi-language cinema specifically rather than shorthand for all Indian film, is headquartered here too, which is one more reason Bandra and the northern suburbs reward a full day rather than a rushed pass-through.
We’ve built the day-by-day version for every trip length once the visa, the season and the transport basics above are locked in: the 2-day itinerary , 3-day itinerary , 4-day itinerary , 5-day itinerary , 6-day itinerary and 7-day itinerary all build on the same route, just longer.
