Three days in Mumbai (formerly Bombay) keeps the same South Mumbai spine as the 2-day plan, the Fort’s UNESCO walk, the Gateway of India, the Elephanta ferry and Dhobi Ghat, then tacks on one genuinely offbeat third day: a stepped temple tank on Malabar Hill, a shrine you can only reach at low tide, an Irani cafe, and a Bandra wander. It’s still South Mumbai plus a day, not the whole city; Dharavi and the northern suburbs are further out.

Two days in Mumbai (formerly Bombay) is South Mumbai’s greatest hits, angled slightly off the postcard route: the Fort district’s UNESCO Art Deco blocks instead of just the Gateway photo, Sassoon Dock’s fish auction instead of a mall food court, and the Elephanta Caves ferry instead of a second round of Marine Drive. It is not the whole city. Bandra, Dharavi and the northern suburbs stay off the map this trip, and that is the honest tradeoff for a weekend.

Mumbai’s headline circuit, Gateway of India, Marine Drive, CSMT, the Elephanta ferry when the weather cooperates, fills maybe two days before it starts repeating. Formerly Bombay, renamed in November 1995, India’s largest city and financial capital holds a second layer most first-timers walk straight past: a laundry ghat viewed from a footbridge, a lunchbox relay running since 1890, a pagoda whose dome needs no pillars to hold it up. These 9 spots are real, checkable, and close enough to the classic route that skipping them takes more effort than seeing them.

Four days in Mumbai (formerly Bombay) keeps the same South Mumbai spine as the shorter versions of this route, the Fort’s UNESCO walk, the Gateway of India, Elephanta, Dhobi Ghat, Banganga Tank, Haji Ali and Bandra, then earns a genuinely different fourth day: north to Sanjay Gandhi National Park and the Kanheri Caves, plus a Dharavi tour that treats Dharavi as the working manufacturing district it actually is, not a spectacle.

Five days in Mumbai (formerly Bombay) is enough to cover the postcard route and then push past it: the South Mumbai UNESCO core and the Elephanta ferry first, then a full extra layer most first-timers skip, a tide-locked shrine, the northern suburbs’ rock-cut caves, an honest look at Dharavi, and a whole day built around food and markets instead of monuments. It still isn’t everywhere; the northern beaches and a day trip out to Pune stay off this map.

Six days in Mumbai (formerly Bombay) is enough to run the full South Mumbai offbeat spine, add real time in the northern suburbs most first-timers skip, slow down for a food and market day, and still leave the city entirely for a day. Days 1 through 4 keep the same route as the shorter versions of this plan: the Fort’s UNESCO walk, the Elephanta ferry, a Malabar Hill and Bandra detour, then a push north to the Kanheri Caves and Dharavi.

Most first-time visitors do the same three things in Mumbai: the Gateway of India, a walk down Marine Drive, a look at CSMT from outside. All three are worth doing. None of them explain why the city looks or works the way it does, and the explanation sits one layer down, in a market that opens before the tour buses, a tank older than the name “Mumbai,” a cafe culture that outlasted the empire that produced it, and a stretch of the same Marine Drive most of those first-timers already walked without knowing it was UNESCO-listed.

Seven days in Mumbai (formerly Bombay) is the offbeat family’s fullest version of this route: five days that run the entire city core, then two full days out of it instead of the single either-or day the 6-day version has to compress into one. Days 1 through 5 stay inside Mumbai for the Fort’s UNESCO walk, the Elephanta ferry, an offbeat shrine day, a push into the northern suburbs, and a whole day built around food and markets.
