Kleinwalsertal is a part of Mittelberg, Vorarlberg, Austria. It is part of the Bregenz district and due to the geographic location in the Allgäu Alps with its alpine terrain, the Kleinwalsertal has no direct traffic connection to the rest of Vorarlberg. It is accessible only via Oberstdorf, Germany, to the north, and thus is an Austrian "practical exclave" or "pene-exclave".
