We got there by tuk tuk, it costs 80 Rupee (1.2$) from central bus station one way. We spent several hours there, but you might need less. There are a lot of tuk tuks near the entrance to Bibi Ka Maqbara, so it won’t be the problem to return back home.
Entrance fee is 200 Rupees (3$) for foreigners and 15 Rupees for locals.
Bibi Ka Maqbara is located in Aurangabad. Aurangabad is a good starting point for visiting Ellora and Ajanta caves.
How we got to Aurangabad
We reached Aurangabad by night sleeper bus from Indore (bus agency was Hans Travel and the bus quality was good, it was AC sleeper bus with blankets, TV and even toilet!)
If you are going to Aurangabad from Mumbai there are four daily trains connecting Mumbai with Aurangabad railway station.
Where we lived in Aurangabad
It was hard to understand where it is better to live in Aurangabad when we booked the hotel in advance, but we had chosen very nice option - hotel Pearls. I really recommend this hotel to everyone (double room costs 26$ if booking through Agoda), as it was one of the best hotels we lived in during our 1,5 month traveling around India.
