Bikaner is a desert city with camel tours, and with National research centre on Camel. If you have balls to see the rat temple, make short trip to Deshnok. But, it smells horribly there.
Bikaner’s treasure is Junagarh Fort, and its museum. Beautiful paintings and architecture. Otherwise, Bikaner doesn’t belong to the list of cities to visit, it’s quiet boring there.
Unfortunately, also to find the budget hotel was painful.
