The best way to see India is at ground level on the Indian railway system, and not at 30,000 feet. In fact, no visit to India would be complete without the experience of travelling on Indian trains and negotiating busy Indian railway stations! Train travel is safe, cheap and (in AC classes) comfortable. Even long distances such as Bombay to Delhi or Delhi to Varanasi can be covered more time-effectively than flying, using overnight sleeper trains.
