Central India drive
Delhi is one great city to hit the road from: to the North lie the Himalaya, to the south is the Thar desert, to the east is the Gangetic heartland. Head southeast, and you enter a fascinating world of ancient monuments, dense forests, fascinating rivers and, well, the Taj. Take in the world heritage monuments of Agra, the medieval forts of Gwalior (pic) and Jhansi, gaze upon tigers in Panna, and at the gorgeous temples of Orchha and Khajuraho. Give yourself a week or ten days and watch middle India come alive.
