Is it possible to get into the Arkham City area in the game? (Batman: Arkham Knight)

Miracle tower was demolished

it would be fun to know if you can get to Arkham Asylum or old Gotham - this is where the events of Batman Arkham Origins take place. It would also be interesting to see the city of Arkham City, and whether it is possible to get there at all. That's what I would like to know, because it would be just wonderful.

By the way, is it possible to ride in the game only on the Batmobile?, otherwise, as far as I remember, Batman still has a Batplane plane, as well as a boat and even a bike, but I don’t know if they are in this game.

to the hospital for story only. and the old Gotham - it was either demolished, or it is located on one of the other islands

actually, one of the Riddler's riddles is to scan a standing tower just, maybe it's all broken, but not demolished!

it is unlikely that it was demolished, since it is part of the main Gotham

Death_Cold
means on other islands remained.

Climb up and look for the Miracle Tower. The entire area of ​​Arkham City is drawn, but you can't fly up to it. Arkham City can also be found on the map to the right of Miagani Island. Clearly visible from the Wayne Tower. You can also see Arkham Asylum, it is to the left of Arkham City (it was still visible in AC).
