Here is some in-depth road trip analysis on a Canadian Thanksgiving weekend:
The zoos are listed in the order that I visited them on my 95-zoo, 33-day European journey.
19 zoos with Asian Elephants: Artis Royal Zoo (Amsterdam, NL), Diergaarde Blijdorp (Rotterdam, NL), Zoo Maubeuge (Maubeuge, FR), Zoo Antwerp (Antwerp, BE), Planckendael Zoo (Mechelen, BE), Pairi Daiza (Brugelette, BE), Cologne Zoo (Cologne, DE), Krefeld Zoo (Krefeld, DE), Dierenrijk (Animal Kingdom) (Nuenen, NL), Burgers' Zoo (Arnhem, NL), Tierpark Hagenbeck (Hamburg, DE), Berlin Zoo (Berlin, DE), Berlin Tierpark (Berlin, DE), Erlebnis Zoo Hannover (Hannover, DE), Tierpark Strohen (Wagenfeld, DE), Osnabruck Zoo (Osnabruck, DE), Allwetterzoo Munster (Munster, DE), Wildlands Adventure Zoo Emmen (Emmen, NL) and Dierenpark Amersfoort (Amersfoort, NL).
3 best Asian Elephant exhibits: Cologne Zoo (Cologne, DE) is easily #1, Planckendael Zoo (Mechelen, BE) is second and Diergaarde Blijdorp (Rotterdam, NL) third. There are, unfortunately, a number of fairly small, disappointing Asian Elephant exhibits that I saw on my trip.

3 best Common Hippo exhibits: Cologne Zoo (Cologne, DE), Wildlands Adventure Zoo Emmen (Emmen, NL) and Berlin Zoo (Berlin, DE). Honourable mention goes to Safaripark Beekse Bergen (Hilvarenbeek, NL) although it lacks underwater viewing.

My favourite Pygmy Hippo exhibit is found at Berlin Zoo (Berlin, DE).
____________________________________________________________________________
7 zoos with Okapis: Diergaarde Blijdorp (Rotterdam, NL), Zoo Antwerp (Antwerp, BE), Frankfurt Zoo (Frankfurt, DE), Cologne Zoo (Cologne, DE), Wuppertal Zoo (Wuppertal, DE), Safaripark Beekse Bergen (Hilvarenbeek, NL) and Berlin Zoo (Berlin, DE).
I think that all 7 Okapi exhibits are decent, with perhaps my favourite being Diergaarde Blijdorp (Rotterdam, NL).
11 zoos with Polar Bears: Diergaarde Blijdorp (Rotterdam, NL), Safari Parc Monde Sauvage (Aywaille, BE), Wuppertal Zoo (Wuppertal, DE), Dierenrijk (Animal Kingdom) (Nuenen, NL), Ouwehands Dierenpark (Rhenen, NL), Tierpark Hagenbeck (Hamburg, DE), Berlin Zoo (Berlin, DE), Berlin Tierpark (Berlin, DE), Erlebnis Zoo Hannover (Hannover, DE), Osnabruck Zoo (Osnabruck, DE) – hybrid bear with Silver Fox and Wildlands Adventure Zoo Emmen (Emmen, NL).
3 best Polar Bear exhibits: Erlebnis Zoo Hannover (Hannover, DE) is by far and away the best, followed by Ouwehands Dierenpark (Rhenen, NL) and Diergaarde Blijdorp (Rotterdam, NL).
3 zoos with Giant Pandas: Pairi Daiza (Brugelette, BE), Ouwehands Dierenpark (Rhenen, NL) and Berlin Zoo (Berlin, DE).

3 best Chimpanzee exhibits: Burgers' Zoo (Arnhem, NL), Osnabruck Zoo (Osnabruck, DE) and Safaripark Beekse Bergen (Hilvarenbeek, NL). There are at least 10 Chimpanzee exhibits that I would rate as ranging from mediocre to awful, with the European zoos that I visited doing poorly when it comes to our closest relatives.
17 zoos with Lowland Gorillas: Artis Royal Zoo (Amsterdam, NL) with Meerkat and Diana Monkey, Diergaarde Blijdorp (Rotterdam, NL), Zoo Antwerp (Antwerp, BE), Pairi Daiza (Brugelette, BE) with Colobus, GaiaZOO (Kerkrade, NL) with Black-crested Mangabey, Frankfurt Zoo (Frankfurt, DE), Cologne Zoo (Cologne, DE) with King Colobus, Wuppertal Zoo (Wuppertal, DE), Duisburg Zoo (Duisburg, DE), Krefeld Zoo (Krefeld, DE), Safaripark Beekse Bergen (Hilvarenbeek, NL) with Colobus as well as Black-crested Mangabey, Ouwehands Dierenpark (Rhenen, NL) with Colobus, Apenheul Primate Park (Apeldoorn, NL), Burgers' Zoo (Arnhem, NL), Berlin Zoo (Berlin, DE), Erlebnis Zoo Hannover (Hannover, DE) and Allwetterzoo Munster (Munster, DE) with Red-capped Mangabey.

3 best Bonobo exhibits: Planckendael Zoo (Mechelen, BE) is apparently the world’s largest Bonobo exhibit and there are a series of indoor rooms as well, Apenheul Primate Park (Apeldoorn, NL) is second and Frankfurt Zoo (Frankfurt, DE) third.

15 zoos with Aquariums (only including those buildings of a substantial size): Artis Royal Zoo (Amsterdam, NL), Diergaarde Blijdorp (Rotterdam, NL), Zoo Antwerp (Antwerp, BE), Pairi Daiza (Brugelette, BE), Frankfurt Zoo (Frankfurt, DE), Cologne Zoo (Cologne, DE), Wuppertal Zoo (Wuppertal, DE), Tierpark + Fossilium Bochum (Bochum, DE), Duisburg Zoo (Duisburg, DE), Ouwehands Dierenpark (Rhenen, NL), Burgers' Zoo (Arnhem, NL), Tierpark Hagenbeck (Hamburg, DE), Berlin Zoo (Berlin, DE), Osnabruck Zoo (Osnabruck, DE) and Allwetterzoo Munster (Munster, DE).
3 best Aquariums: Diergaarde Blijdorp (Rotterdam, NL), Burgers' Zoo (Arnhem, NL) and Berlin Zoo (Berlin, DE).
____________________________________________________________________________
11 zoos with Tropical Houses (only including those buildings of a substantial size): Pakawi Park (Olmen, BE), Pairi Daiza (Brugelette, BE), Mondo Verde (Landgraaf, NL), Cologne Zoo (Cologne, DE), Dortmund Zoo (Dortmund, DE), ZOOM Erlebniswelt (Gelsenkirchen, DE), Krefeld Zoo (Krefeld, DE), Burgers' Zoo (Arnhem, NL), Weltvogelpark Walsrode (Walsrode, DE), Allwetterzoo Munster (Munster, DE) and Wildlands Adventure Zoo Emmen (Emmen, NL).
3 best Tropical Houses: Burgers' Zoo (Arnhem, NL) and Wildlands Adventure Zoo Emmen (Emmen, NL) are the two stand-out Tropical Houses that I saw on the trip and they are just about the two largest in all of Europe. (Zurich and Leipzig would perhaps round out a ‘Top 4’ list). It’s difficult to make a third selection, but I’ll go with Pairi Daiza (Brugelette, BE) for the inclusion of Sulawesi Bear Cuscus, Bulwer’s Pheasant, St. Lucia Amazon Parrot, St. Vincent Parrot and Andean Cock-of-the-Rock in its decent Tropical House.

12 zoos with Reptile Houses (only including those buildings of a substantial size): Artis Royal Zoo (Amsterdam, NL), Zoo Antwerp (Antwerp, BE), Pairi Daiza (Brugelette, BE), Frankfurt Zoo (Frankfurt, DE), Zoo Neuwied (Neuwied, DE), Cologne Zoo (Cologne, DE), Wuppertal Zoo (Wuppertal, DE), Tierpark + Fossilium Bochum (Bochum, DE), Tierpark Hagenbeck (Hamburg, DE), Berlin Zoo (Berlin, DE), Osnabruck Zoo (Osnabruck, DE) and Allwetterzoo Munster (Munster, DE).
5 best Reptile Houses: I want to highlight 5 exceptional Reptile Houses in this category. My #1 choice would be Berlin Zoo (Berlin, DE) with its 91 reptile/amphibian species and 64 exhibits on the upper levels of the greatest zoo building in the world, followed by Cologne Zoo (Cologne, DE) with its 58 species and 60 exhibits, then Zoo Antwerp (Antwerp, BE) with its 77 species, 43 exhibits and small walk-through ‘jungle’ area. You can’t go wrong with Berlin, Cologne and Antwerp in this category. However, the top floor of the Exotarium at Frankfurt Zoo (Frankfurt, DE) is excellent and there are 69 reptile/amphibian species there. Finally, Zoo Neuwied (Neuwied, DE) also has an ‘Exotarium’ and it is excellent, with 55 species and 38 exhibits.
____________________________________________________________________________
3 zoos with Nocturnal Houses (only including those buildings of a substantial size): Zoo Antwerp (Antwerp, BE), Frankfurt Zoo (Frankfurt, DE) and Dierenpark Amersfoort (Amersfoort, NL).
I did not include Zoo Neuwied (Neuwied, DE) as there are only 3 exhibits in a room, or several other zoos with a couple of nocturnal exhibits. There were only 3 ‘proper’ Nocturnal Houses on the trip and now Antwerp has already closed theirs down! Those buildings are endangered species in modern zoos.
3 zoos with Insectariums: Artis Royal Zoo (Amsterdam, NL) has 33 species, Cologne Zoo (Cologne, DE) has 42 exhibits and Berlin Zoo (Berlin, DE) has 51 species. There are also a number of zoos with small invertebrate collections, including Pairi Daiza (Brugelette, BE) with its large wall of terrariums.
Here are the top 10 zoos on the trip:
1- Berlin Zoo (Berlin, DE)
2- Pairi Daiza (Brugelette, BE)
3- Cologne Zoo (Cologne, DE)
4- Burgers' Zoo (Arnhem, NL)
5- Diergaarde Blijdorp (Rotterdam, NL)
6- Berlin Tierpark (Berlin, DE)
7- Frankfurt Zoo (Frankfurt, DE)
8- Artis Royal Zoo (Amsterdam, NL)
9- Planckendael Zoo (Mechelen, BE)
10- Zoo Antwerp (Antwerp, BE)
That makes it 4 from Germany, 3 from Belgium and 3 from the Netherlands.
Honourable mention: Apenheul Primate Park (Apeldoorn, NL) – I loved my visit, but this is a difficult zoo to compare to my Top 10. Apenheul is not even open year-round, has basically nothing but primates, but is still a ‘must-see’ zoological experience and I had a fantastic time there.
