Earth Pyramids, a wonder of nature. The Renon Earth Pyramids are the highest and the most aesthetically pleasing in Europe. Earth pyramids are a phenomenon of erosion. They originate where ice-age glaciers have deposited moraine clay in valleys. When it is dry, it is rock-hard. If it comes into contact with water, it turns into a clayey pulp that flows down into the valley. However, when protected from the rain by large stones, the clay remains dry and hard. Only the part around the stone erodes. This is how earth columns are formed and become higher each time it rains. If the top stone falls off the peak, the column is certainly doomed to a quick decline because the clay is exposed to the rain and then carried away by it. The earth pyramids in the valley of the Rio Gasterer at Auna di Sotto have a special grey colour.

Route: from the car park at Kalterer See lake, continue north to the Geier restaurant. Behind the restaurant, a narrow trail leads to the north into the orchards. Walk along these and turn off to the right in an easterly direction following the markers. At the slope on the eastern side of the valley, turn right, passing by the hotel on the left to the Klughammer road. First follow this road, then continue on a trail above the road.

This trail ends at the southern end of the lake. Cross the road to join the Nature Discovery Trail (Naturerlebnisweg). At the end of this nature trail, turn right onto the so-called Kuchlweg trail, hiking to the vineyards on the western side of the valley. Just before the wine road, turn right into the trail through the field, following it until you reach the point where the wine road curves to the right. Cross over and now follow a trail through the field once more. Then follow the footpath next to the wine road to the church of San Giuseppe al Lago/St. Josef am See (Kirche St. Josef). Take the farm track to the right back to the starting point of the hike.
