The wooden fence is higher than what might appear in the photo, and inside the field is deeper, there are irons in the top to prevent the bears to climb.
I seem to recall that there are hot wires too. The irons on the top are to stop visitors falling in and I would suggest a little lightweight to contain the bears.
They are Brown Bears. I think I recall seeing about five of them.
My typical complaint of late: the exhibit may well be fine for the animals (although keeping 5 bears together is problematic), but the enclosure design suggests a prison stockade--ugly visible walls and hotwires, with people looking down on the animals. It just looks crude
