Golden Triangle (India)

India's golden triangle is a tourist circuit which connects the national capital Delhi, Agra and Jaipur. The Golden Triangle is so called because of the triangular shape formed by the locations of New Delhi, Agra and Rajasthan on a map. The trips usually start in Delhi moving south to the site of Taj Mahal at Agra, then west, to the desert landscapes of Rajasthan. It is normally possible to do the trip by coach or private journey through most tour operators. The Golden Triangle is now a well-traveled route providing a good spectrum of the country's different landscapes. The circuit is about 720 km by road. Each leg is about 4 to 6 hours of drive. The Shatabdi express train also connects Delhi with Agra and Jaipur.
