Can you not walk the entire way around the rhino enclosure (The one that has the under passage out from the indoor house) these days? I read recently they still hold meerkats in their original enclosure at the back of the rhinos, but these are now used for off-show experiences.
@Baringogiraffe12 No, the loop is now blocked off fully, with just this small areas of direct viewing the central paddock. There's good viewing along the paddock opposite the Tsavo Aviary, on the paddock attached to the house from the path towards the Aardvarks and wild dogs, and of course of the paddock behind Cafe Bembe as well though, so it doesn't feel as restricted as it might.
