Jaisalmer is beautiful, royal and more vibrant than you can imagine. But truth be told, there's only that much you can do there. Two days are enough for Jaisalmer (half a day more MAX) and you can cover it all, very comfortably in that duration.
We landed around noon, checked into our room and started walking towards the fort.
While the lanes leading to the fort aren't very pleasing, the fort as soon as you enter makes it all worth it.
We walked around, explored cafes, saw a 450 year old haveli and managed to not get caught up in shopping spree. It's a huge fort so keep your sports shoes ready and prepare yourself to walk. You'll see beautiful local houses, shops, folk singers, dancers and musicians. The local craftsmanship is applaudable.
By evening we were tired so we took an auto back to our hotel and relaxed on the stunning terrace which has the entire city and fort view.
TIP: Bargain while shopping. Bargain with the local auto guys too. Everything is quoted double the amount.
