The Adelegg forms the northernmost foothills of the Allgäu Alps in the southeastern part of the Bavarian Alps and extend a long way out into the Alpine Foreland. They lie between the Untere Argen near Isny to the southwest and west, and Leutkirch to the northwest (both in the Baden-Württemberg district of Ravensburg), and between Altusried to the northeast, Wiggensbach to the east, Buchenberg to the southeast and the Wengener Argen near Weitnau to the south (all in the Bavarian district of Oberallgäu).
