The Amur tiger exhibit is excellent, with lots of space, climbing structures, pools, two indoor viewing areas, and a maternity area. In particular this larger outdoor area is very good, but . . . for the tigers only. too bad if you want to see them, or take pictures. As m30t pointed out on his recent picture, this glass obscures the visitor's view, it is tinted, and condensation sticks to it.
If you stand on the rock on the right, if you are tall, if you have a suitable view-finder, if the tiger comes by, you can get a good picture.
For this area the only good place is through the glass at the end on the left that is not shown here. There is no view the length of the exhibit from there. You also have to listen to an awful video that plays there. My picture just before this shows Kira from there.
