New Delhi is the seat of India's central government, and the metropolis around it runs on public administration, services, retail and the corporate offices of Gurugram and Noida. Three UNESCO World Heritage Sites lie within the city: the Red Fort complex, the Qutb Minar and its monuments, and Humayun's Tomb. Visitors come for those sites, for the food lanes of Old Delhi and for trade fairs at Pragati Maidan, and many use Delhi as the first stop before Agra, Jaipur or the hills of Himachal and Uttarakhand.
For a two or three day stay, Connaught Place, Paharganj and Karol Bagh sit on the Blue and Yellow metro lines, while Aerocity suits early departures because it is next to the airport. The Delhi Metro is the quickest way across the city, and a smart card or a QR ticket bought on a phone saves time at the counters. October to March is the main sightseeing season, though smog can be heavy in November, and Diwali week fills hotels and trains. May and June are extremely hot.
The Red Fort is closed on Mondays. At Jama Masjid and Gurudwara Bangla Sahib, remove your shoes and cover your shoulders and legs; the gurudwara also asks everyone to cover their head and lends scarves at the entrance. Swaminarayan Akshardham does not allow phones or cameras inside, so leave them in the cloakroom or at the hotel.
October to March, with days of about 7-30°C; November can bring heavy smog. April to June often passes 40°C.
By Air: Indira Gandhi International Airport (DEL) is about 16 km south-west of Connaught Place; allow 40-60 minutes by road, more at peak hours. The Airport Express metro line links Terminal 3 with New Delhi station, the Magenta Line serves Terminal 1, and prepaid taxis and app cabs run from all terminals.
By Rail: New Delhi, Hazrat Nizamuddin, Old Delhi and Anand Vihar Terminal are the main stations. Vande Bharat trains run to Varanasi, Amritsar and Katra, and Rajdhani services link the city with Mumbai, Kolkata and Chennai.
By Road: NH 44 runs north to Punjab and Kashmir, the Yamuna Expressway reaches Agra, and the Delhi-Mumbai Expressway is open in sections to the south-west. State and private buses leave from the Kashmere Gate, Anand Vihar and Sarai Kale Khan bus terminals.

Chennai, called Madras until 1996, is one of India's largest metropolitan areas, with car plants along the Sriperumbudur and Oragadam belt, a busy container port and a large share of the country's medical travel. Its December music and dance season is the biggest event in the Carnatic calendar. Visitors use the city as the gateway to the Shore Temple at Mahabalipuram, the silk and temple town of Kanchipuram and the former French enclave of Puducherry along the East Coast Road.
For a short trip, Egmore, Nungambakkam and T. Nagar are central and well served by the metro, while Mylapore and Besant Nagar put you close to the older temples and the beach. Chennai Metro's Blue Line runs from the airport through the city to Chennai Central, and the Green Line links Chennai Central with St. Thomas Mount via Koyambedu. South India's first air-conditioned suburban train started on the Beach to Chengalpattu line in April 2025, and the older suburban trains and MTC buses are inexpensive but crowded at peak hours. App cabs and auto-rickshaws fill the gaps.
The weather is kindest from November to February. The north-east monsoon brings most of Chennai's rain in October and November, and cyclones in those months can disrupt flights and flood roads. The Margazhi music and dance season runs through December into January, with concerts at sabhas across Mylapore and T. Nagar, and Pongal in mid-January closes many offices for several days. At the Kapaleeshwarar Temple and other Hindu temples, remove footwear and dress modestly with shoulders and knees covered. Marina Beach is for walking rather than swimming, as the currents are strong. For Mahabalipuram, leave early to see the Shore Temple before the midday heat, and combine it with the Pancha Rathas and Arjuna's Penance nearby.
November to February, with days of about 24-30°C and lower humidity. October and November bring the north-east monsoon rains.
By Air: Chennai International Airport (MAA) is at Tirusulam, about 21 km south-west of the city centre; allow 45-75 minutes by road. The Blue Line metro stops at the airport, Tirusulam suburban station is linked to the terminals, and MTC buses, prepaid taxis and app cabs are available.
