By Air – Most major international airlines operate in what is one of the best-connected cities in south Asia. Delhi has separate domestic and international airports that lie 8km (5 miles) apart; a free hourly shuttle bus runs between them. Tip: During high inflow periods the shuttle times may be increased but bear in mind that, should you merely be in transit ie arriving at international terminal and due to connect with a domestic flight somewhere in India, you will have to factor in enough time to wait for this shuttle bus to transfer you. Alternatively, make sure you have enough time to draw money from an ATM and catch a cab between the two terminals; cost is around Rs 250. Also, note that the domestic airport has two terminals, 1A and 1B, also connected by free shuttle bus; check which one you need to be at before leaving.
The Delhi Metro is increasingly useful, particularly for covering longer distance, but as is the case elsewhere, subways also provide no sense of the city layout or passing sights. During peak hours, the tube can also get overcrowded and claustrophobic, and women traveling alone may get unwelcome attention. Ticketing agents are still not very clued in or helpful, either. However, it’s a very cheap and effective way of getting around, particularly if your lodgings are near a station, in which case you should definitely purchase a 1-day card, or a 3-day if you’re staying longer.
You can book an air-conditioned bus tour of New Delhi and/or Old Delhi through Delhi Tourism. Tours cost Rs 100 each, or Rs 195 for both; monument admission fees are extra. Also offered are long-distance tours that include trips to Agra, Jaipur, and Rishikesh, but we definitely recommend you opt for a private operator. Two of the most popular are Go Delhi Luxury Tours, and TCI . Their tours are more personal, and the higher tariff ensures that you get a decent English-speaking guide and an air-conditioned vehicle. Another reliable option which comes highly recommended is Le Passage to India it would be best to check with all three for the best rate available. But if you’re tired of predictable presentations of history, we urge you to book a tour with the unusual Blowhorn Travel who provide a series of innovative itineraries, keeping the idiosyncrasies of Indian culture in mind, and often studying it through the eyes of interesting personalities such as Lucy Peck, architectural historian and Khushwant Singh, son of a builder; truly a breath of fresh air to tourism gone stale, and catering to one to eight persons max. If Old Delhi is your focus, we also recommend Tallis & Company whose services and guides are extremely professional and thorough.
