India is a huge country and in many cases tourists visiting a resort wish to stay there longer and "get into the atmosphere". So most of the green tourists there choose to focus on a certain area. But if you wish to know theoretically "the Indian highlights", here thay are:
Delhi - India's capital and the center of the tourists in North India.
Mumbai - a "bit" of Victorian London in South East Asia
Goa - a piece of a Catholic culture and a Western approach
Kolkata - the capital of West Bengal
Agra - the city of the famous Taj Mahal
Varansi - the religious capital of India, situated on the banks of river Ganges
Bon Voyage
