Another poster was looking for info on Almabtrieb dates in September. You might be interested, too. This refers to events where cattle or sheep are brought down from the high alpine meadows in preparation for winter. The cattle wear special traditional decorations and a festival atmosphere prevails. Good timing for your trip.
