Start at Chhatrapati Shivaji Maharaj International Airport in Andheri, allowing at least two hours before your Mumbai–Delhi departure—more if you are checking luggage or travelling during the monsoon. A nonstop flight takes roughly 2–2.5 hours; use the airport’s prepaid taxis, app cabs, or Metro Line 3 connections for the terminal, and check your airline’s terminal carefully before leaving. Since the sightseeing plan begins in South Mumbai after the flight, arrange luggage storage at your Delhi accommodation or confirm early check-in rather than carrying bags around.
After landing and settling in Delhi is not part of this day’s route; instead, following the Mumbai sightseeing sequence, spend about 1.5 hours wandering the Kala Ghoda Arts Precinct in Fort. The galleries and heritage façades are best enjoyed at an unhurried pace, though some galleries close on Mondays and individual hours vary, so treat this as an exterior-and-neighborhood walk if needed. From Kala Ghoda, take a short taxi or walk toward Gateway of India—roughly 10–15 minutes by car depending on traffic—and spend 45 minutes by the waterfront, looking across the harbor and around the surrounding plaza. Keep phones and wallets secure near the busiest photospots, and avoid unsolicited boat or guide offers unless you have checked the official pricing.
Walk or take a brief cab ride through Colaba to Leopold Cafe for a casual early dinner or snacks; budget approximately ₹600–1,200 per person. It is a lively, historic stop rather than a quiet café, so go early if you want a table without much waiting. Afterwards, take a taxi toward Marine Drive—allow 20–30 minutes in evening traffic—and finish with an hour on the promenade as the lights come on along the bay. The sea breeze is welcome in August, but Mumbai’s monsoon can bring sudden rain: carry a compact umbrella, wear shoes with grip, and use a cab rather than walking the whole way if the pavement is slick.
Take an early nonstop flight from Mumbai to Indira Gandhi International Airport, ideally departing around 6:00–7:00 AM so you can reach central Delhi by late morning. Allow 3–4 hours overall for the airport process, baggage, and the transfer into the city; a pre-booked app cab is easiest, while the Airport Express metro is useful if your hotel is near New Delhi Railway Station or Connaught Place. Leave luggage at your hotel before heading to Humayun’s Tomb in Nizamuddin. The tomb complex is generally open from sunrise to sunset, with entry around ₹50 for Indian visitors and ₹600 for foreign visitors; allow about 1½ hours to wander through the charbagh gardens and admire the red sandstone architecture. August can be humid and rainy, so carry water and use the shaded walkways where possible.
A short 10–15-minute auto-rickshaw or cab ride brings you to Lodhi Garden, where the broad lawns and 15th-century tombs make for a calmer introduction to Delhi than its busier monuments. Spend about an hour walking the central paths; mornings and late afternoons are liveliest, but the garden remains pleasant after lunch as long as the weather is dry. Continue by cab for roughly 10 minutes to Khan Market, an easy place to browse independent shops, bookshops, and small food counters without committing to a long formal meal. Stop at Khan Chacha for a filling kebab or roll lunch—budget approximately ₹500–1,000 per person—and leave some time for a cool drink or dessert nearby. The market is usually busiest in the evening, and many shops close on Sundays, though restaurants generally keep longer hours.
From Khan Market, take a 10–15-minute cab ride toward India Gate; traffic around Kartavya Path can build after sunset, so allow extra time. End with a relaxed 45-minute walk around the monument and the broad ceremonial boulevard, when the lights come on and Delhi families gather for the cooler air. There is no entry fee, but avoid unofficial parking touts and use a marked car park or app-cab drop-off. If rain begins, wait it out at Khan Market before leaving rather than attempting the exposed lawns; otherwise, this is a gentle first evening in Delhi after a full travel day.
