The hut Clarahütte is already in the middle of the alpine wilderness of the Hohe Tauern National Park. The mighty Rötspitze (3495m) towers over the valley.
The Iseltrail first runs across wide, flowery alpine meadows. Over a steep step, which was covered by glaciers only a few decades ago, you reach the arctic climate zone. You finally reach the "birthplace" of the Isel at the glacier tongue of the Umbalkees, below the Dreiherrenspitze (3499m).
The way back to the parking place Sröden (free bus connection) should not be underestimated: For the 12 kilometres and 1000 metres of altitude difference on the way down, you should calculate a good three hours of walking time.
