A few weeks ago I finally got the opportunity to visit this zoo for the first time. I had somewhat high expectations, especially as all my friends with more of an architectural background were absolutely crazy about this place and I had seen what the same architect was already doing on a small scale in Amiens. But unfortunately the zoo did not quite live up to my expectations, though this would be an easy thing to fix.
For starters, the great rock really is something else and a tremendous zoo icon. What is also very well done is the planting and I really like that the architects chose not to hide that this is a zoo. So plenty of classical zoo structures like cages, over moated enclosures, which with the limited space would be awkward. In terms of sight lines the zoo really is a hit and miss, with many superb views where the visitor really is guided to see (or not see) certain things, but at several points there was also obvious cross viewing that could have been hidden more easily.
My real problem is however the overcrowding of especially the Guyanan, Malagasy and European part of the zoo. Especially in the greenhouse, but also around it there are just too many small exhibits. Especially in the rainforest hall this takes away any illusion of a rainforest, though the free-flying macaws make up for that. But it also means there are many exhibits in this area that are either on the small side of just clearly too small and the great planting and structure of the exhibits cannot hide that. While structure can make up for a lesser size, as the puma exhibit clearly shows, there is a minimum size before structure alone is enough. Clearly the jaguars got the short end of the stick. It would have been preferable to see slightly less, but larger exhibits here. This doesn't necessarily mean much less animals, as there is still potential for larger mixed-species exhibits.
It might be stereotypically French, but 99.5% of all education was in French, generally the only English/Spanish were the common names on most signs, but for free-ranging species or in the large aviary, French was the only option. There is a (prohibitively expensive) guidebook in English, but for such an international tourist attraction, the lack of English was appalling.
