I was in Edinburgh last week, for the festival, and paid a very quick visit to the zoo. The negative reviews do not surprise me. The Pandas are invisible. The Lions are indeed blocked off (how on Earth did they ever breed in traditional Lion Houses, I wonder, when in 2019 they require a 100 metre exclusion zone when cubs may be imminent?). Lots of older areas are no longer in use. And there are huge lengths of (steep) pathway that do not lead to any great reward. Entry is pretty expensive as well (£22 for an adult). But there are a lot of Meerkats. And those lego sculptures too. Hurrah!
Some positives, of course: the Chimpanzee thing is great (even if it doesn't give the killer view of the animals); Penguin area is very good. Ermmmm. South American primates are done well. Macropod walkthrough is good. Tiger exhibit looks excellent - but you need to be lucky to see a tiger. Apart from that....
Edinburgh Zoo has really gone downhill recently (which is ironic). I visited back in July and I think I saw more lego animals than real ones. I was hopeful that, with the new Panda enclosure, I would actually get to see the Pandas (which I still haven't seen since they got them) and of course, they weren't out. The Tigers were at least partially visible but all the visitors that were crowding around the exhibit were facing a keeper who was talking about them instead of actually looking at the animal oddly. Further on, the Lion exhibit was behind barriers and the only things visible at the top were the deer and vicuna, which to be honest I could see at practically any zoo or wildlife park so not a crowd drawer.
The amount of Meerkat enclosures is absurd and the majority of old exhibits that used to house some real rarities are now pretty much permanently empty.
It still has positives though - Koala Territory is one (obviously having such an unusual species is a bonus and the actual layout of the enclosure is nice), the Rhino exhibit is still ok and of course Penguin Rock, Budongo Trail and some of the walk-throughs. Hopefully when the new Giraffe house is built and open it might boost the zoo's popularity again and prompt them to start filling up some of the empty spaces, otherwise it's just not worth visiting anytime soon.
