Hike to the natural monument Birnbachloch and the Birnbachloch Glacier, the lowest glacier in Central Europe. This route impresses with the quiet, untouched surroundings at the foot of the Leoganger Steinberge.
The hike begins in the Leoganger Ullachtal/Passauer Hut and first leads through forest, then along the hiking trail through meadows and later more rocky terrain up to Birnbachloch at 1291 m. The Birnbachloch is a karst spring with an approximately 20 m wide "entrance hall." Inside this hall, the Birnbach springs. A few hundred meters from Birnbachloch, the hiker encounters the Birnbach Glacier, the lowest glacier in Central Europe. It has a significant history, as at the end of the 19th century, Munich breweries obtained ice here for their ice cellars. Ice blocks were transported down the mountain on hundreds of meters long wooden slides.
