Stretching from the frozen summits of the Himalayas to the tropical greenery of Kerala, India’s expansive borders encompass an incomparable range of landscapes, cultures and people. Walk the streets of any city when you travel India and you’ll rub shoulders with representatives of several of the world’s great faiths, encounter temple rituals performed since the time of the Egyptian Pharaohs, onion-domed mosques erected centuries before the Taj Mahal, and quirky echoes of the British Raj on virtually every corner.
