Gorner Gorge (Gorner Gorge / Geologischer Pfad)

The Gornerschlucht, or Gorner Gorge, is a narrow ravine cut by the Gornera, the glacial stream that drains the Gorner glacier above Zermatt. It lies on the south side of the village, a short walk from the centre, and it is one of the easiest ways to see what water and rock can do together. The stream is fed by meltwater from one of the largest glacier systems in the Alps, so it flows fast and carries a heavy load of fine rock flour, which gives the water a milky blue-green tint in summer. Over thousands of years, this stream has cut a deep, narrow channel through the rock, leaving smooth, curving walls and potholes.

The rock itself is part of the attraction. The gorge is cut into a zone of greenish rock, serpentinite, which is typical of the Zermatt region and is linked to the history of the Alps as a collision zone between continents. Serpentinite is a metamorphic rock formed from fragments of old ocean floor, and its colours range from dark green to nearly black, often with polished or waxy surfaces. In the gorge you can see it close up, with the tracks left by ice and water on the walls. Information boards along the path explain how the gorge formed and what the rock is, so it works as a small outdoor geology lesson.

Visitors walk through the gorge on wooden walkways and stairs attached to the rock walls, built in the late nineteenth century and rebuilt and repaired many times since. The path leads through the narrowest part of the ravine, where the walls close in and the roar of the water is loud, and then comes out into a more open area with views up the valley. The route takes around twenty minutes to walk, and it is secured with railings and well maintained, which makes it suitable for children and for people without much mountain experience. Because the spray keeps the wood and rock wet, the surfaces can be slippery, so sturdy shoes with good grip are important, and a light waterproof jacket is useful on hot days when the temperature in the gorge is lower than outside.

The gorge is open in the warm months, usually from late spring to autumn, and an entrance fee is normally charged. Opening dates and hours depend on snow and weather, so check with the Zermatt tourist office before you go. The path can be combined with other short outings nearby. A glacier garden, with potholes and polished rock surfaces left by the ice age, lies in the same area, and walking trails lead onward toward the higher viewpoints and the mountain hamlets on the slopes above the village.

The Gorner Gorge suits families, geology enthusiasts and anyone looking for a short, easy outing from Zermatt that does not require a lift ticket. It is a good choice on a day when the mountains are covered in cloud, since the gorge is impressive in any weather. Allow about one hour for the walk and the viewpoints, longer if you linger to read the information boards or extend the walk into the surrounding area. Avoid visiting after heavy rain if the water level is very high, since parts of the path may be closed.
