a very large enclosure. The viewing is from an overhead walkway at one end, but the gate was locked when I was there so I could only get a photo from the side of the gate, hence most of the view is cut off. Suffice to say the enclosure extends a Long way further on from what you can see here.
The tiger(s) in here are orange. The white tigers were in much smaller enclosures to the other side of the walkway (but also viewable from ground level).
For everything else at the zoo, see my review here:
