The Guggersee is a small mountain lake in the Southeastern Walsertal Mountains (Südöstliche Walsertaler Berge), a subgroup of the Allgäu Alps.
It is located at a height of 1,709 metres,[1] above the Rappenalpbach valley in the municipality of Oberstdorf. The lake lies 1,035 metres as the crow flies southwest of and below the Alpgundkopf (2,177 m) on a Panorama Way (Panoramaweg)[1] between Birgsau in the valley and the Mindelheim Hut (2,013 m). On this path, 455 metres southwest at a height of 1,727 metres, is the alm of Vordere Tauferbergsalpe. From Birgsau the lake is about 2 hours walk.
The lake is 49 metres long and a maximum of 25 metres wide. It has a shore length of 119 metres and an area of around 843 m².[2] Formerly it was up to 75 metres long, but the northern part has silted up.
