This route trades the lakes of Udaipur for the desert. You see the Pink City of Jaipur, the Blue City of Jodhpur under its great fort, and Jaisalmer, the golden city that rises out of the sand.
Jaisalmer is the reward for the long drives. Two nights there give you the living fort, the carved havelis and a camel ride across the Sam dunes at sunset. If you want to sleep under the stars, ask for a night in a desert camp.
Distances are long, so each leg is planned with breaks, and the final day is built around your onward flight or train from Jodhpur or Jaisalmer.
