The Galterntal with its Galtern Gorge is a real leisure and natural paradise. Along the gorge, countless bridges, arches, footbridges and walkways line the steep walls. Joggers and hikers alike are out and about here. For dogs, the four-legged gorge walkers, the builders of the bridges have here and there made paw-friendly attachments so that the animals do not injure their paws on the partially metal perforated plates.

La Lamberta Excavated in the molasse, they have 200 meters of galleries. The infantry work intended for the machine gun position is one of the scattered fortifications set up during the First World War to defend the Swiss Plateau. The construction of this infantry work took place between 1916 and 1917 and made it possible to protect the axis of Lake Morat. Today these caves have become a paradise for children for long games of hide-and-seek. https://www.j3l.ch/fr/P8751/lieux/sites-naturels/les-grottes-des-roches-grises-la-lamberta

The Galternbach is a tributary of the Saane. It flows into the Saane at the Bern Bridge in Freiburg. Coming from the village of Galtern in the east, the stream flows westwards in wide curves and meanders through a long, wooded valley, which in places narrows like a gorge. Here, at a loop of the Galternbach, bridges lead over the stream. There is a nice rest area on a flat hill in the gorge!

The Galternbach is a tributary of the Saane. It flows into the Saane at the Bern Bridge in Freiburg. Coming from the village of Galtern in the east, the stream flows westwards in wide curves, meandering through a long, wooded valley that narrows in places like a gorge. At this curve, the wonderful hiking trail leads over a bridge and thus changes from one side of the stream to the other. On the left side of the stream (east of the bridge), the trail leads down/up the steep valley slope in bends, mostly with wooden steps; on the other (right) side (west of the bridge), the trail leads along the steep slope on a wooden footbridge, partly with steps. All in all, an exciting section of the Galtern trail!
