The regional Route 42 "Aargauer Weg" connects Frick AG and Muri AG. This FKT is done in either direction, starting at the train station in Frick and finishing in Muri, or reverse. The vertical gain is about the same. It has three detours to train stations or places of interest in the towns of Aargau, Baden and Mellingen, which should not be abbreviated.
