Hohe Tauern National Park

Listen for a moment. Somewhere below you, meltwater is running over stone. The air is thin and cool, even in summer, and it carries the faint smell of wet rock and alpine grass. Then a sharp whistle cuts through the quiet. That is a marmot, warning the others that you have arrived. Welcome to Hohe Tauern, the high mountain heart of Austria, where Carinthia rises toward ice and sky.

This is the largest national park in Austria, and one of the largest protected areas in the Alps. It covers more than 1,800 square kilometres, shared between three Austrian provinces: Carinthia, Salzburg and Tyrol. Carinthia was the first to act. Its part of the park was protected in 1981, and the other two provinces followed in later years. So the side of the mountains where you stand now is where the whole idea began.

Look up, and you may see the reason so many people come here. The Grossglockner rises above the valleys at about 3,798 metres. It is the highest mountain in Austria. Its summit is a sharp pyramid of dark rock and snow, and on clear days it looks almost too steep to be real. Clouds often gather around the peak by midday, so morning usually gives the cleanest view.

Here is a detail many visitors miss. The first recorded ascent of the Grossglockner took place in 1800, and it was a Carinthian project. A prince-bishop of Gurk, the old Catholic diocese of Carinthia, organised and funded the expedition. Huts were built on the approach, and a team of climbers, guides and local men reached the top. In a sense, the story of mountaineering on this peak began with a churchman's ambition.

Below the mountain lies the Pasterze, the longest glacier in Austria. From a distance it looks like a grey-white river frozen in place, curving down between the slopes. Up close, it is less clean than you might expect. The surface is streaked with gravel, dust and boulders carried down from the ridges above. The ice moves very slowly, and it shapes the valley as it goes.

Now the second surprise, and it is a sobering one. The Pasterze is shrinking, and you can see it with your own eyes. Along the path toward the glacier, markers show where the ice edge stood in past years. Each marker is further from the ice than the one before. Older visitors who return after decades often say the same thing: the glacier is not where they remember it. The bare grey rock between the markers is the record of a warming climate.

Many people reach this high country by the Grossglockner High Alpine Road. It opened in 1935, during hard economic years, and it was built partly to create work and partly to bring travellers into the mountains. The road climbs in long hairpin bends, and each turn opens a new view. Engineers designed it to follow the land, so it rises with the slopes instead of cutting straight through them.

At the end of a spur from that road is a viewpoint called Kaiser-Franz-Josefs-Höhe. It takes its name from Emperor Franz Joseph, who came to this area with Empress Elisabeth in the middle of the nineteenth century. Today the terrace looks straight across to the Grossglockner and down onto the Pasterze. On busy summer days it fills with voices in many languages, yet the scale of the view still makes people go quiet.

Keep your eyes on the rocks and the grassy slopes. Alpine marmots live here in large numbers. They are round, sandy-brown animals that sit upright at the entrance to their burrows. Higher up, you may see Alpine ibex, wild goats with long curved horns, standing calmly on ledges that look impossible to reach. Both animals have learned that people on the paths are usually harmless, so patient visitors are often rewarded.

Look to the sky as well. Large birds of prey circle above these ridges. Golden eagles nest in the park. The bearded vulture, a huge bird that once vanished from the Alps, has been brought back through a long reintroduction programme, and Hohe Tauern played an important part in that work. Seeing one is rare and depends on luck. But if a very large bird with long narrow wings glides past, take a second look.

Down in the valley, the village of Heiligenblut sits at the foot of the mountain road. Its tall, slender church spire stands against the Grossglockner, one of the most photographed scenes in Austria. The name means holy blood. Legend has it that a traveller carried a small vessel containing a drop of the blood of Christ through these mountains, and died in the snow nearby. Locals say the church was built to keep the relic. It is a story of faith, not documented history, but it gave the village its name.

The park is not only about high peaks. It also protects alpine pastures, larch and stone pine forests, moorland and dozens of mountain lakes. Farmers have grazed cattle and sheep on these meadows for centuries, and that work is part of the landscape. In early summer the pastures fill with flowers: gentians in deep blue, alpine roses in pink, and small white blossoms between the stones. The wooden huts and stone walls you pass were built by people who lived with this land.

Weather changes quickly up here. A warm, bright morning can turn cold and grey within an hour. Wind comes off the glacier, and fog can close the view completely. That is why experienced walkers carry a warm layer and rain protection, even on a sunny day. Stay on the marked paths. They protect fragile plants, and they keep you safe on slopes where loose rock and old snow can hide danger.

Before you move on, stand still for one more minute. Notice the colour of the ice, the sound of water under the stones, the way the light moves across the rock faces as the clouds pass. This landscape was shaped over thousands of years, and it is still changing as you watch. When you walk away, listen for that marmot whistle again. It is the sound of the mountains going on with their own quiet life.
