If you can share more inputs like your place of arrival and departure and how many days in hand excluding arrival and departure can suggest the best one.
Hey Akshaya,
In Jodhpur.. you should visit the Mehrangarh Fort and Umaid Bhavan palace. In Jaipur, you can visit Amer Fort, Jantar Mantar, Nahargarh fort, Jaigarh fort, City Palace, Chowkhi Dhani, Birla Temple, etc. Do reserve a day for shopping either in Jaipur or Jodhpur.
Forts in Jaipur having grand character are Amer Fort, Nahargarh Fort and Jaigarh Fort as the top priority in the list. Pink City is well known around the world for its spectacular forts and magnificent palaces which reflect the science of Indian architecture and the glory of Rajputs.
