Leave Sugiez railway station, cross the Broye canal and continue until you reach a gentle slope and the vines used to produce a wine that has AOC classification in both Fribourg and Vaud (the only bi-cantonal AOC in Switzerland). Continue along the route until you arrive at the Roches Grises caves, above the wine-growing village of Môtier. Spend a few minutes visiting the galleries dug out in the molasse before returning to the path towards the Réduit du Vully, an important infantry support base during the two great wars of the 20th century.

Next, enter an area of undergrowth to discover the Pierre Agassiz – named after a famous scientist from the region, who tracked the rock’s movements to prove the existence of glaciation – and then head back to the summit of Mont Vully, with its stunning views over the Three-Lakes Region, the Jura and the Alps.

Carry on until you reach a Celtic fortified town, called an oppidum. It dates from the Celtic period, about 124 BC. The Helvetians once occupied this hillside before they departed for Gaul and were stopped by Julius Caesar. Take a detour to the Tour des Sarrasins on the way down. Then head back towards the vines to return to the starting point, enjoying the unique view over Lake Murten. Tip: don’t miss the opportunity to taste some regional specialities, such as the local wines and the famous Vully Tart!
