Air: Jaipur's Sanganer Airport is just south of the city (15 km) from where you can hire a taxi (Rs 250-300) to the city centre.
Rail: From Delhi, there are many trains that connect Jaipur and other cities in Rajasthan; foremost among them is the Palace on Wheels. Other important trains include, Shatabdi Express and Pink City Express.
Road: NH8 connects Delhi and Jaipur. It's ideal for a drive. Avoid driving at dusk, though, which is when most of the accidents happen on this most accident-prone highway in the country. Jaipur is part of the Golden Travel Circuit of India that includes Delhi, Agra, and Jaipur. Rajasthan Tourism operates deluxe buses for most of these tours.
