@Nix It probably is my favourite of what I've seen - but there's a lot of the newer ones I haven't. Pairi Daiza's outdoors might beat it, but I'm not a fan of the caves.
@Nix To be honest I've only been there once, and a decade ago now, so my memories are not strong. I remember having really good views of active pandas here, though. Beauval had another good one, I recall.
