Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.

Khajuraho is a UNESCO World Heritage Site in Madhya Pradesh.

The north Indian city of Varanasi, or Benares, is regarded as sacred by Hindus, Buddhists and Jains. Situated in the fertile Ganga valley and on the banks of the Ganges, Varanasi is a place of pilgrimage for Hindus, who come to bathe in the holy river.

It’s also a centre of silk weaving, so practise haggling at the chaotic bazaar for some beautiful souvenirs. Rickshaws are the best way to get about.

Visakhapatnam truly offers something for every type of traveler, from the beach bum to the culture vulture.
