We haven't personally explored Jodhpur but here's a link to a quick round-up of some Jodhpur must dos / visits by two of our favorite travel bloggers / influencers - https://www.bruisedpassports.com/wheres/things-to-do-in-jodhpur-india
Mehrangarh fort
Mehrangadh, RJ 344702, India
We certainly recommend exploring Mehrangarh Fort. The Fort is on a height and we've been told that the climb can be steep. Make sure to keep at least 3-4 hours to fully enjoy exploring the property.
