This tour will take you around St Glucker's Chapel (on the site of what once was Saint-Léger village) and farther on up to Neiweiher pond. Walk along the stream that runs through the floral village of Hirtzbach and explore Reinach Park, the last icehouse in Sundgau and its castle. Do not hesitate to visit them! You can also see Sonnenberg Institute, a private school, which was a spa in 1850.
