The ascent of the 'Südostpfeiler' (Southeast Pillar) in the Tennen Mountains, graded 5+, is an iconic and highly sought-after alpine climbing experience. This prominent pillar offers sustained climbing on excellent limestone, though typical for the region, some sections may present looser rock or grassy ledges, demanding careful route-finding and a high level of alpine awareness. The route generally follows a logical line up the impressive buttress, providing exposure and a real sense of verticality. While the technical difficulties at 5+ are within reach for experienced multi-pitch climbers, the overall commitment, the long approach, and the often complex descent make it a serious full-day undertaking. The rewards are immense: thrilling climbing, breathtaking panoramic views of the surrounding Alps, and a profound sense of accomplishment upon reaching the summit. It truly embodies the spirit of traditional alpine climbing.
