The world’s most populous country has much to offer visitors. Many first-time visitors explore the Extended Golden Triangle which includes the cities of Delhi, Udaipur, Jodhpur, Jaipur and Agra and such famous sites as the Taj Mahal.
India can be quite daunting if you arrive unprepared so I strongly recommend a read of this book prior to leaving home. Of course, you need to take it with you as a continuing source of information while you travel around.
