It looks like a reasonable amount of enclosures hat been renovated lately - not all of it has been finished. Looks somehow like a software project - more than 6 month late and still not finished...
All together a great day. The picture impressions are containing more fences and tiles than the ones from more modern zoos but we also got more eye-contact with the animals.
So everything has pros and cons. Looking forward to visit Burgers Zoo again ...
BTW - don't go for Glühwein or wafers from the cabin shop at the entrance - poor quality. For the one's with kids: They do have a limited number of pull carts available. Free of charge - coins available at the entrance.
