What did you think about the zoo? I'm really considering visiting it since the Iberian lynx wasn't visible in Jerez when I went this summer and the aviary is impressive.
It's worth a visit - a little rough around the edges in places but some nice surprises species-wise and a very interesting layout. Lots of antelope, which is nice. It won't be topping anyone's favourite zoo list, I suspect, but that applies to a lot of places. I visited mainly for the Iberian Lynx and certainly didn't regret the decision!
