Sumatran Tiger Exhibit at Barcelona, 30/05/11

Is there any fence separating people from going onto the grassy area?

Hmmm... trying to remember. I think it's a low standoff as you can see here, which is the other side of the path: http://www.zoochat.com/467/tapir-mara-exhibit-barcelona-30-05-a-223368/

First, you have a fence, and then the grass that you see. At the end there's a pit with water. The fence and the distance between visitors and the pit is exactly the same that the lion exhibit. The only difference is that the lion's pit has not water.
