Hellabrunn Zoo

Listen for a moment before you walk any further. Beneath the calls of birds and the low chatter of visitors, there is often another sound — the steady rush of water. The river Isar runs right beside this zoo, and its meadows shape everything around you. The air here feels cooler and greener than in central Munich. Gravel crunches underfoot, old trees throw patches of shade across the paths, and somewhere ahead an animal you cannot yet see is moving through the undergrowth.

Welcome to Hellabrunn Zoo, in the south of Munich, in the Thalkirchen district. It sits on the floodplain of the Isar, on land that was once part of an old estate called Hellabrunn. That is where the name comes from. The setting matters. Instead of a tight urban block, the zoo spreads across wooded riverside ground of around forty hectares. You will notice streams, ponds and stands of mature trees. Much of the landscape was here long before the enclosures were built.

The zoo first opened its gates in 1911. Munich at that time was a confident, growing city, and a zoological garden was a mark of civic pride. But the early years were hard. The First World War brought shortages, and the economic chaos that followed made the zoo very difficult to run. In 1922 it closed. For several years, there was no zoo here at all.

It reopened in 1928, and the man who led that new beginning was Heinz Heck. He stayed as director for decades, and his name is tied to one of the strangest projects in zoo history. Heck, together with his brother Lutz, who ran the Berlin zoo, tried to breed back animals that had disappeared from Europe. Their best-known target was the aurochs — the huge wild ox that once roamed the continent and died out in the seventeenth century.

Here is the first surprise for many visitors. The brothers crossed different breeds of domestic cattle, choosing animals that looked primitive. The result became known as Heck cattle. They are not true aurochs, and scientists today are clear about that. They are a modern breed that only resembles the ancient animal. The Hecks attempted something similar with wild horses as well. The project has a complicated reputation, partly because of the political climate of the 1930s. Yet Heck cattle still graze in parks and nature reserves across Europe.

The second surprise is about the layout under your feet. In the 1970s, Hellabrunn reorganised itself as what it called a Geo-Zoo. The idea was simple. Animals would be grouped by the part of the world they come from, not by species type. So instead of a monkey house next to a cat house, you walk through regions. Hellabrunn is often described as the first zoo in the world to be planned fully this way. As you walk, try to notice how the plants, rocks and water change from one area to the next.

One building deserves your attention, whatever else you plan to see. The elephant house, with its large dome, dates from the 1910s, from the zoo's earliest period. It is a protected historic building. Its rounded roof and heavy, solid walls belong to a time when animal houses were built to impress people, almost like small palaces. In recent years, the building was carefully renovated inside, so the elephants have more modern conditions. The old shell stands around a very different idea of animal care.

That contrast runs through the whole zoo. In the early twentieth century, the goal was to display animals. Today, zoos like this one talk about conservation, breeding programmes for endangered species, and education. You can see the change in the enclosures themselves. Many older cages have been replaced with open spaces, water moats and planted areas. Some animals will be hard to spot. That is partly the point — they have places to retreat from the crowd.

If you head towards the great apes, you will reach the jungle house. Inside, the air is warm and heavy with humidity. Gorillas and chimpanzees live here, and these are often the most absorbing animals in the whole zoo. Stand still for a few minutes. Watch how the adults sit, how the young ones test the limits, how they look back at you. Many visitors move on quickly. The ones who wait usually see the most.

In the polar area, the mood changes completely. Here the focus is on cold-climate animals, including polar bears and penguins. Water is central to this part of the zoo. Look for viewing windows where you can watch animals below the surface. A polar bear on land can seem slow and heavy. Under water, it moves with surprising ease. Penguins are similar — awkward on rocks, fast and smooth once they dive.

For families, there is a quieter corner built around farm animals and a small village atmosphere, with a petting area. It is a reminder that a zoo is not only about exotic creatures. Goats, sheep and other domestic animals sit alongside the wild ones. In a zoo once famous for trying to rebuild ancient cattle, this mix of wild and domestic feels quite fitting. The story of how humans shaped animals runs through the whole site.

Give yourself time here. The zoo is large, and the paths loop and branch through the trees. It is easy to spend most of a day and still miss things. Comfortable shoes help. So does a loose plan. Pick the regions you most want to see, then allow yourself to drift. Animals are often more active in the morning or later in the afternoon, when the day is cooler.

It is also worth remembering where you are in the city. Just outside, the Isar meadows are one of Munich's favourite outdoor spaces. On warm days, local people cycle along the river, swim, sunbathe on the gravel banks and grill in the open air. The zoo is part of that green belt along the river. When you leave, you can easily continue on foot or by bike along the water.

Before you move on, pause wherever you are standing now. Look up at the trees above the path. Many of them are older than most of the buildings here. Listen again for the river. The zoo has closed, reopened, and changed its whole philosophy over more than a century. The Isar has kept flowing past through all of it. As you walk away, notice how the sound of the water stays with you a little longer than the sound of the crowd.
