In southern Germany, Bavaria and Austria, Fasching equals fat Tuesday and what better way to celebrate Mardi Gras than by tubing the icy waters of the Chattahoochee River in the Alpine Village of Helen. At 2 p.m. Saturday, Faschingsverein Helen will parade around town, followed by a tubing parade through the middle of Helen. That evening, a Fasching party will be from 7-11 p.m. at the Helendorf River Inn and Conference Center, 33 Munich Strasse, Helen.
