Then, the sun tears away that curtain and jagged rocks appear, an iron cross gracing their peak. This is the eastern Alps most impressive summit and Austria’s highest peak – the Grossglockner, the ”Black Mountain”. Climbing three thousand seven hundred and ninety eight meters, Mount Grossglockner – the fateful summit of early mountaineers, towers above the Tauern massif like a sentinel over an Alpine paradise of nature. Ibex and chamois climb the rocks, Alpine flowers glow in the sun and golden eagles glide over the mountain peaks.
