Erguël Bike

“A great route in the valley of St-Imier featuring both nature and culture. I was surprised by the many sights starting from the Longines factory and then passing the nearby ruins of Erguël castle. At the end of the journey, my friend and I decided to go and visit the Spielhofer cheese dairy.”
