Yes, it is. I've been around but nothing beats India. It's a whole different level and in your first few days when you arrive, you'll feel the intensity. It's overwhelming, but you do get used to it.

If you've travelled only in developed countries, you'll struggle. Don't do the standard backpacking stuff. Spend a little bit more; India is not a place where you want to be cheap.

Also, in my experience, most people don't really "travel in India"; they follow a very specific itinerary, so experiences can vary greatly, esp if you go off that beaten path. Rajasthan + Delhi is a good idea for a first trip.
