Crossing the river. We are at the end of the Belfort gap, the southern gateway to Alsace. After the bridge on the right, the path follows the stream and allows you to see a small weir on the left. The Steinbaechlein is a diversion of the Doller and its crystal clear water from the Vosges made the prosperity of the Mulhouse textile industry (DMC, etc.). Cross the road when you come to it.
