Being located in theWestallgäu, the market town is bordering on the region of theBregenz Forest, part of theAustrian administrative region ofVorarlberg. TheHausbachklamm belongs to the prominent landmarks and sights of Weiler-Simmerberg, as well as theEnschenstein and theWildrosenmoos. Even though the landscape is rather mild, there are many very cliffy and steep rock faces due to the irregular bedding of sandstone and conglomerate.
