Kleinwalsertal is a part of Mittelberg in the Austrian province of Vorarlberg.
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". Prior to Austria joining the European Union, the area had tax-free status.
The local football club, SV Kleinwalsertal, has the distinction of being one of only a few clubs in Central Europe that play in a local league based outside of the club's country. They play in the 10th tier A-Klasse Allgäu 4 in 2016–17.
