Tour of 6km (2 hours) through forest and along Bruche in order to visit the oldest church of Alsace: the Dompeter. Nearby, the Pétronille source and the rest of the thousand-year-old lime tree touched down by the lightning. The path lined with red beech leads to the center of Avolsheim and the chapel Saint-Ulrich. The return path is after the Bruche bridge in the direction of Molsheim.
