I haven't been to Beauval in many years, but I do have three pieces of advice:
- Don't miss the bird show - missing out on this is the biggest regret from my visit, as it looks unbelievable in videos and is probably the best in Europe
- The Harpy Eagles and Douc Langurs are the most commonly mentioned species as major lifeticks not to miss out on, but another lovely primate kept at Beauval which isn't discussed enough is the Moustached Monkey, a scarcely kept guenon and a really nice species. They are kept in the long row of primate enclosures between the chimpanzees and tigers which is currently known as 'the Monkey Pathways,' but on my visits had the much more interesting name of 'Primates Peculiarities.'
- In terms of a route, Beauval gets ridiculously busy after lunchtime (based on my own visits and what regulars I met at the zoo told me on said visit), so I would recommend making your way towards what interests you first and getting it out of the way, although of course allow yourself to take in some of the other interesting animals and exhibits you pass on route. For me, this meant going to the pandas, as at the time of my visit I had never seen them before, via the big cats, orangutans and Australian animals, and that worked for me very well so I would recommend it. That said, making your way to the hippos and the dome first via the savannah and sea lions, for example, would work just as well.
That is all I can think of, but no doubt regulars and locals will be able to give you much better advice. Beauval is an amazing zoo and probably one of the best in Europe, but sadly there are some fairly poor enclosures ('the Big Cat Woodlands,' known on my visit as 'Carnivores, Curiosities and Oddities,' is probably one of the worst rosters of carnivore enclosures in Europe), so another tip I would give to help get the most enjoyment out of your visit is to temper your expectations and don't assume every enclosure will be perfect, or else you will be disappointed. By lowering the standard a little, you are bound to be amazed, as the best Beauval has to offer truly is remarkable.
