Have you ever felt a nearly metallic sensation in your mouth? Well, that’s what can happen in the Aare Gorge (locally known as the Aareschlucht), a crack a little over one kilometer long that opens in the heart of the Bernese Oberland. The reason is simple (and interesting): here the air comes from the bowels of the mountain, laden with humidity and ancient stories.
Between the villages of Meiringen and Innertkirchen, the eponymous river flows at times gentle and at other times furious. It tightens, accelerates, roars and then changes color with the light, shifting from a pale gray to turquoise reflections that betray the glacier origin of the water. At the same time, vertical walls rise up to 200 meters above the head, with smooth surfaces marked by pale veins and deep engravings. In some places the distance between the two walls narrows to just over a meter, so that hands can touch the rock on both sides.
But this is also a place full of mysteries: in the Alpine valleys for centuries the legend of the Tatzelwurm, an undefined creature, half serpent and half dragon, circulated. According to popular tales it lived right between these walls, fueling for a long time the fear of crossing the area. A fear that kept locals away until the late 19th century, when someone decided that this fracture in the mountain deserved to be walked through.
Origins and Characteristics of the Aare Gorge
Everything is born long before the Alps as we know them today. The rock that forms the Kirchet massif dates back to the Cretaceous period, between 130 and 60 million years ago. At that time there was an ancient sea here, the Tetide, whose marine sediments gradually deposited until they became solid limestone over time.
When the Alpine chain began to rise about 15 million years ago, these layers folded and were pushed upward, consolidating a sturdy rocky barrier. The Kirchet, however, maintained a relatively stable structure. And indeed this very compactness made erosion work slower, but also more spectacular.
During the ice ages, starting about one or two million years ago, enormous masses of ice polished the rock surface without destroying it. The decisive change, however, comes during the warmer periods between glaciations. In these phases the ice retreats and the water takes control.
The Aare River, fed by glacier melt, finds a way and begins to erode. Not just once, but through multiple cycles of glacial advance and retreat that have created several gorges over time. Some are now filled with morainic debris, while the current Aareschlucht represents the latest version of this process, the most recent and visible.
The result is a precise incision, with surfaces smoothed by the water, cavities carved by vortices and glacial potholes that testify to the rotational force of sediments dragged by the flow. Yes, it is a continuous energy that has never ceased.
How the Visit to the Aare Gorge Works and What to See
Access to this Swiss treasure takes place through two distinct entrances, one on the Meiringen side, the other toward Innertkirchen. The full opening of the route depends on the season, with complete passage available in the warmer months.
The itinerary unfolds on wooden walkways supported by metal structures, anchored directly to the rock. In other stretches, carved galleries allow crossing points that would otherwise be impractical, and protections are clearly present along the entire route. The average time to walk the entire gorge is around 45 minutes, but the actual duration depends on how much you’re able to slow down.
Stopping becomes inevitable, also because some zones catch the eye more than others: a sudden narrows, a ray of light entering obliquely, the contrast between darkness and reflections on the water, and so on. In the summer months, precisely between July and August, on Friday and Saturday evenings the canyon is transformed with artificial lighting.
The walls take on different tones, while the river becomes a moving strip of light. There are also fewer tourists than in daylight hours, so the whole experience is quieter and there is more space to perceive the place directly. The internal climate remains cool even on the hottest days, a natural feature that makes the visit pleasant during the sultry hours. In case of rain, the experience changes again because the water flow increases, with a corresponding rise in noise and greater visual intensity.
An interesting detail concerns accessibility: the initial stretch on the western side has been adapted to allow passage for light wheelchairs and narrow strollers. The rest of the route requires a freer mobility, but without significant technical difficulties. Outside the entrances there are small facilities welcoming visitors, including a main restaurant and a bistro with a terrace from which to enjoy an exhilarating view of the surrounding Alps.
For the return, there is, instead, a curious local railway line that links the two ends of the gorge, with the return trip included in the admission ticket (thus avoiding walking the same stretch twice).
Where It Is and How to Get There
The Aare Gorge is located in the Haslital, a transversal valley crossing the Bernese Alps. It stretches from the Grimsel Pass to Lake Brienz, linking environments as varied as high mountains, hydroelectric infrastructures, and historic villages. The closest point to reach it is Meiringen, a town also known for another literary curiosity linked to Sherlock Holmes. From here the western entrance is reached in a few minutes. Innertkirchen represents the reference for the eastern entrance.
Those arriving by car will find parking near the entrances. Alternatively, the regional train Meiringen–Innertkirchen stops at stations a short distance from the entrances, from which a short walk leads to the start of the route.
The geographical setting deserves attention, because the gorge appears as a must-pass, a point where the river has imposed its will on the mountain. Those who reach here are hardly indifferent, because one has the concrete sense of being inside something still active. An open wound in the rock that continues to change, millimeter by millimeter.
