I visited 4 sites of this WHS in December 2011-January 2012. There are several forts in Rajasthan but the ones inscribed in this WHS are really unique. My personal favourite is Jaisalmer Fort in the Thar Desert close to the Pakistan border. It is special because it is still inhabited and the people there are really special. Hopefully sanitation problems and refuse collection will improve thanks to UNESCO but I really hope that the rumours of Jaisalmer becoming a "tourist attraction" meaning that the locals would be "accommodated" in apartments "outside" the city walls does not materialise (similar to what has happened in Bagan, Burma or Angkor Wat, Siem Reap). Jaisalmer Fort is special and unique to me because it is still inhabited after hundreds or thousands of years. I also visited Amber Fort outside Jaipur (entering the fort gate on a painted elephant like a maharajah), Ranthambore Fort, and Chittorgarh Fort with the claustrophobic Victory Tower.
