Between 90 minutes and two hours to enjoy the view. I went with my family on a night with clear skies and the view is amazing. But as it is closed unlike the empire state the photos are not so good.
If about 2 hours at most depends a lot on the queues that have that day Buy the online ticket ticket
From the moment you arrive to buy the ticket you must dedicate 3 hours or four to finish the tour.
I tell you my experience, which coincided with that of my entire family. We had a day that, although it wasn't raining, it wasn't totally clear. We got to see approximately until the 50 st; I think that a day with good visibility can be more attractive. We spend less than 90 minutes on it. The entire observatory is fully closed. The rwflwjia in the glasses do not allow good photographs
At least 2 hours
