Jodhpur is the gateway to the Rajasthan desert: a vast fort on a rock above a maze of blue-painted houses. Adding it to the Golden Triangle gives you a fort of a very different scale from Amber, and a feel of western Rajasthan.
The route runs one way, from Delhi to Agra and Jaipur and then to Jodhpur, about 340 km (210 miles) from Jaipur and five and a half to six hours. We break it with a stop at Ajmer or Pushkar if you wish. You end in Jodhpur, which has an airport and train station.
