Bro In Rajasthan countless places for travelling where you get new vibes.
I think If you are coming to Rajasthan for the first time then you should start from Jaipur. The view of Jaipur on Diwali is completely different.
You should also explore places like Udaipur, Jodhpur, Jaisalmer, you will get to see a lot. I am from Jhalawar, Rajasthan which is famous for Gagron fort. Jhalawar is a very beautiful place and after Diwali a fair of Chandrabhaga is also organized in Jhalrapatan which is very attractive indeed.
