Delhi is India's capital and one of the world's great historic cities — a place where Mughal monuments, colonial boulevards, ancient ruins, and a roaring modern metropolis occupy the same map.
Delhi — officially the National Capital Territory of Delhi — is not one city but many layered on top of each other. Historians count at least eight distinct cities on this site going back 5,000 years: Indraprastha of the Mahabharata, the Tomara and Chahamana Rajput settlements, the Sultanate capital of Qila Rai Pithora, Siri, Tughlaqabad, Firozabad, Shahjahanabad (Old Delhi), and finally Lutyens' New Delhi. Each layer left monuments, bazaars, and neighbourhoods that coexist in the present city.
Modern Delhi is also a city of sharp contrasts. The broad, tree-lined avenues of New Delhi — designed by Edwin Lutyens and Herbert Baker for the British Raj — lead past the Rashtrapati Bhavan and Parliament House to Connaught Place. A few kilometres north, the narrow lanes of Shahjahanabad (Old Delhi) pack mosques, havelis, spice markets, and some of India's most celebrated street food into a dense medieval grid. South Delhi, meanwhile, has evolved into a world of upscale neighbourhoods, malls, and the IIT campus.
Delhi is the gateway to the Golden Triangle (Delhi–Agra–Jaipur), and its international airport makes it the entry point for most foreign visitors to North India. For Indian domestic travellers, it is the most connected hub in the country by air.
Delhi's climate is extreme by Indian standards — intensely hot summers and genuinely cold winters make timing critical.
Travel tip: January fog regularly causes flight delays and diversions at IGI Airport. If you're visiting in December–January, build buffer time into connections and check FlightGPT for real-time fare changes if delays force a rebook.
Delhi's monuments and neighbourhoods each deserve unhurried attention. Here is a curated selection:
Delhi is served by Indira Gandhi International Airport (IATA: DEL), India's busiest airport. Terminal 3 (T3) handles most domestic and all international flights. The Airport Express Metro Line connects T3 to New Delhi Railway Station in 19 minutes (₹60), and to Dwarka/Connaught Place. Cabs via Ola/Uber take 35–60 minutes to central Delhi depending on traffic.
IndiGo, Air India, SpiceJet, and Akasa Air all operate high-frequency Delhi routes. Compare live fares on FlightGPT — Delhi routes often have flash sales mid-week.
Delhi's size means that location choice dramatically affects your experience of the city.
Food: Delhi's food scene is one of India's most diverse, shaped by Punjabi, Mughal, and UP traditions. Butter chicken and dal makhani were invented here (at Moti Mahal restaurant in Daryaganj, now a chain). Old Delhi's Paranthe Wali Gali has been serving stuffed flatbreads since the 1870s. For street food, Chandni Chowk's Natraj Dahi Bhalle (₹60) and the chhole bhature at Sitaram Diwan Chand (₹80) are institutions. The Lodi Colony neighbourhood has excellent modern Indian dining.
Getting around: Delhi's Metro network is the best in India — 390 km of track covering virtually every tourist area. A single-journey token costs ₹10–60; a Tourist Card (₹200 for 1 day, ₹500 for 3 days) offers unlimited rides. Autos and Ola/Uber are widely available. Avoid driving yourself — traffic and parking are brutal.
Practical tips for Indian travellers:
October to March is the best time to visit Delhi. October and November offer ideal weather — clear skies and 20–28°C temperatures — along with Diwali festivities. December–January are cold (4–10°C at night) but great for sightseeing. Avoid April–June when temperatures can hit 45°C, and note that January fog regularly delays flights at IGI Airport.
The fastest option is the Airport Express Metro Line from Terminal 3, which reaches New Delhi Station in 19 minutes (₹60) and Dwarka Sector 21 in 23 minutes. Ola and Uber cabs from the airport take 35–60 minutes to Connaught Place depending on traffic and typically cost ₹400–600. Pre-paid taxi booths are available outside arrivals.
Delhi is generally safe for tourists during daytime. Use the Metro rather than walking in isolated areas after dark. Solo female travellers should use app-based cabs (Ola/Uber) rather than street autos at night, and the Metro women-only carriages during peak hours. The tourist areas of Connaught Place, Lodi Garden, and Humayun's Tomb are well-policed and busy.
Three days covers the major monuments comfortably — Day 1 for Old Delhi (Red Fort, Jama Masjid, Chandni Chowk), Day 2 for New Delhi (India Gate, Humayun's Tomb, Qutub Minar), and Day 3 for South Delhi (Lodi Garden, Lotus Temple, Hauz Khas). Budget 5 days if you want a day trip to Agra (Taj Mahal) or Jaipur.
IndiGo consistently offers the lowest base fares to Delhi (DEL) on most domestic routes, followed by SpiceJet and Akasa Air. Air India offers better in-flight service and frequent flyer benefits. Fares from Mumbai, Bangalore, and Chennai to Delhi typically start from ₹2,200–2,800 one-way when booked 3–4 weeks ahead. Use FlightGPT to compare all airlines on your specific dates.
