Jaisalmer is a divine place. Sitting in the dessert and seeing on of the best sunset is an amazing feeling. Also staying in the camps and enjoying the Rajasthani culture is also one of the best thing to do. Apart from that , the only living fort offers a variety of ground for shopping. The best part of Jaisalmer is the jeep safari. Do try it whenever you are there.
Overall it is must to go place !
