Yes, the animals are inside a dug out area. From memory, haven’t been in Dubln Zoo for some time. There are IIRC, large boulders and the fence runs on top of them.
So you could easily climb into the area and drop down to where the rhinos are but are not in immediate danger just by being on the wrong side of the fence.
That said we are in danger of turning into Florida on this site.
Just seen the picture a few posts above now. Seems higher up when you are there, I think the ground slopes down towards the boulders/wall.
