Plan a trip by car through Rajasthan in the direction of Jaisalmer if you are in or near the capital. You would travel through Alwar, Jaipur, and Jodhpur with Aravalli beautifying the area with its presence and stopping at local settlements to sample local cuisine.
Map of the Route: You must take NH11 to Jaipur if you want to drive to Jaisalmer from Delhi. Take NH48 toward Jodhpur after spending the night in Jaipur. After spending a few days exploring Jodhpur, take NH125 and NH11 to Jaisalmer.
