Delhi layover itinerary: what you can actually see in 6, 12 and 24 hours
Terminal 3 departures kerb at Indira Gandhi International Airport with taxis waiting at dawn
Three timed plans built around Terminal 3, the 20-minute Airport Express and the 90 minutes of immigration queue you should assume you will lose.
Before you commit: the visa, the queue, the terminal
Leaving Indira Gandhi International on a layover means clearing immigration, and India has no visa-free transit for most passports. You need an e-visa applied for at least four days ahead, or a regular tourist visa; fees run roughly ₹2,000 to ₹8,000 depending on nationality and duration. At T3 the arrivals hall queues 30 minutes on a quiet afternoon and 90 at the pre-dawn bank of long-haul landings between 05:00 and 09:00. Add 20 minutes if a checked bag is tagged to Delhi rather than through to your next city, and subtract three hours at the far end for re-check-in and security.
Two more clock stealers. Traffic peaks between 08:30 and 11:00 and again from 17:30 to 21:00; the 16 km from T3 to India Gate takes 35 minutes at 06:00 and can take 75 at 18:45 on a Friday. And terminals: if you land at T3 but depart from T1, the free inter-terminal shuttle runs on a loop and eats 30 to 45 minutes door to door. The honest cut-off is six hours from wheels-down to next boarding. Under that, do not leave the airport, no matter what the taxi tout at arrivals tells you.
The 6-hour layover: Aerocity, and nothing further
Aerocity sits 4 km from T3 with its own Airport Express station, so the round trip is 25 minutes each way including walking. That is the whole radius you can safely use. The hospitality district is a grid of business hotels around Asset Areas 1 to 6, most of them selling day-use rooms in 4-, 6- and 12-hour blocks for roughly ₹3,500 to ₹7,000, which buys a shower, a bed and a bag-drop. Worldmark and the connected plazas hold enough restaurants that you can eat a proper North Indian meal for ₹700 to ₹1,500 a head without leaving air conditioning.
If you would rather not clear immigration at all, T3 airside has lounges with showers from about ₹2,500 to ₹3,500 for two to three hours, plus sleeping pods in the transit corridor. That is genuinely the better call on a six-hour gap: you keep the buffer, you skip the visa, and you arrive at your next gate unhurried. Do not attempt Qutub Minar, do not attempt Chandni Chowk, and be deeply suspicious of any driver at the kerb offering a four-hour city tour for ₹1,500. He will spend an hour of it in a carpet showroom in Mahipalpur.
The 12-hour daylight layover, hour by hour
Land by 07:30, clear by 09:00, and you have a clean six-hour window in the city. Take a prepaid or app taxi straight to Humayun's Tomb, ₹500 to ₹700 and 35 minutes at that hour. 09:30 to 11:00: the tomb complex, entering via Isa Khan's octagonal enclosure first, which most tour groups walk past. 11:15: cross to Nizamuddin Basti on foot for Ghalib's tomb, the baoli and the narrow lanes of kebab shops. 12:30: eat there, or push 10 minutes west to Khan Market for a cleaner sit-down lunch at ₹800 to ₹1,600 a head.
14:00 to 15:30: Lodhi Garden, which is free, shaded and holds four Sayyid and Lodi-era tombs across 90 acres, with Safdarjung's Tomb a five-minute ride further south if you still have legs. 15:45: coffee in Khan Market or Sunder Nursery. 16:15: start back, allowing 60 to 75 minutes for T3 because the evening peak has begun. That lands you at check-in three hours before a 20:30 departure. The single biggest mistake on this plan is adding Old Delhi to it. Chandni Chowk at midday is a two-hour commitment minimum and the traffic out of it is unpredictable.
The 24-hour layover: a night, a dawn and a fort
An overnight gap is the only version where Old Delhi works. Land in the evening, sleep in Aerocity if you want zero risk, or in Paharganj if you want the city and the Airport Express terminus at New Delhi station on your doorstep. Set an alarm for 06:15. Jama Masjid opens to visitors from around 07:00 and closes to sightseers during prayer slots; the courtyard at that hour, with pigeons and almost no one, is the best 40 minutes in the city. Breakfast on bedmi-aloo and jalebi in the lanes off Chandni Chowk for under ₹150.
09:00: walk Khari Baoli, Asia's biggest spice market, before the handcarts jam it solid. 10:30: Red Fort, closed Mondays, allow 90 minutes. 12:30: lunch at one of the old Muslim-quarter kitchens behind Jama Masjid, ₹300 to ₹600. 14:00: back to the hotel for two hours flat on your back, which is the step people skip and then regret. 16:30: Qutub Minar in the late light, a 45-minute ride south. 18:30: dinner in Hauz Khas or Saket. 20:00: leave for T3. Sleep, if you extend, in the mid-range Aerocity block at ₹6,000 to ₹10,000.
Getting in and out: Express, prepaid taxi or hotel car
The Airport Express, the orange line, runs T3 to New Delhi railway station in about 20 minutes for ₹60, with first departures around 04:45 from the city end and last trains near 23:30 from the airport. It is spotless, has luggage racks, and is immune to the traffic that ruins taxi estimates. Its limitation is the last mile: from New Delhi station you still need an auto or app cab to reach Nizamuddin or Lodhi, and the station forecourt is the single most aggressive touting environment in the city. Walk out, cross to the metro side, book on your phone.
For a timed layover, a car is worth the money. Prepaid taxi counters in the arrivals hall quote around ₹500 to ₹700 to Connaught Place with the fare fixed before you board, which removes the argument. App cabs pick up from the designated bays on the departures level at T3 and often run ₹450 to ₹800 depending on surge. Hotels in Aerocity will send a car for ₹1,200 to ₹2,000, which only makes sense if you have a family and a pile of bags. Never accept a ride from anyone who approaches you inside the terminal.
Bags, showers and the sleep question
T3 has a landside left-luggage counter in the arrivals area charging roughly ₹250 to ₹500 per bag per 12 hours, which is the pivot that makes a 12-hour plan pleasant: go into the city with a daypack, not a suitcase. Airside, the sleeping-pod facility in the transit corridor sells blocks of a few hours, and several lounges include showers, which matters more than a nap after a night flight. Nothing in the city is worth doing while towing a wheeled case through Chandni Chowk, and no monument in Delhi has a cloakroom that will take one.
If you are sleeping in the city, three areas make sense on a layover and the rest do not. Aerocity: 10 minutes from the terminal, business hotels, ₹6,000 to ₹12,000, zero character. Mahipalpur, on the far side of the highway: budget properties at ₹1,500 to ₹3,000, noisy, functional, fine for six hours of sleep. Paharganj: guesthouses at ₹900 to ₹2,500, walking distance to the Airport Express terminus, and the only one of the three where stepping outside for chai at 06:00 is an experience rather than a car park.
What to skip, and the Agra question answered
Agra is 233 km away on the Yamuna Expressway. Even with a private car booked in advance the round trip is 6 to 7 hours of driving plus 3 hours at the Taj, the monument is shut on Fridays, and expressway fog between mid-December and late January can add two hours without warning. Below an 18-hour layover it is a bad bet, and below 24 hours it is a bet you will lose at least one time in five. If the Taj is the point of the trip, build a night in Agra into the itinerary properly rather than gambling a connecting flight on it.
Also skip, on any layover: Akshardham, where the mandatory phone and bag deposit plus airport-style security regularly costs 45 minutes before you see anything; the light-and-sound shows, which start too late to get you back; and the shopping-emporium loop that drivers pitch as included. What repays a short window is anything with a single entrance and open sky — Humayun's Tomb, Lodhi Garden, Qutub Minar, Jama Masjid at dawn. Those four, in that order, are the layover shortlist.
Before you book
What people ask before booking Aerocity.
Yes, for almost every passport. India does not offer visa-free transit through immigration. Apply for the e-visa online at least four days before travel and carry the printed approval. If you stay airside in the international transit corridor at T3 you need nothing beyond an onward boarding pass.
Not quite. First trains from the airport end begin around 05:15 to 05:30, and the city-end first departure is roughly 04:45. For anything landing before 05:00, take a prepaid taxi from the arrivals counter at about ₹500 to ₹700 into central Delhi and use the train on the way back.
The landside cloakroom in the T3 arrivals area takes bags at roughly ₹250 to ₹500 per piece per 12 hours. Aerocity hotels will also hold luggage free if you have bought a day-use room. Do not plan to carry cases into monuments; none has storage.
Only with 18 hours or more and a pre-booked car. Agra is 233 km each way on the Yamuna Expressway, about 3 to 3.5 hours in good conditions, and the Taj closes on Fridays. Winter fog between December and January regularly adds an unplanned two hours to the return leg.
