Aletsch Glacier
At 23 kilometres, the Great Aletsch Glacier in Oberwallis is the longest glacier in the Alps and has been part of the UNESCO World Heritage Swiss Alps Jungfrau-Aletsch since 2001. From the panoramic peaks above the car-free villages of the Aletsch Arena, you can look down on the mighty ice stream, which sweeps in a wide arc from the Jungfrau region into the valley.The three most important viewpoints are the Eggishorn at 2869 metres, accessible by cable cars from Fiesch via Fiescheralp, the Bettmerhorn at 2872 metres above Bettmeralp, and the Moosfluh at 2333 metres above Riederalp. To reach Bettmeralp and Riederalp, you travel by train to Betten or Mörel and from there ascend by cable car. At Konkordiaplatz, where several ice streams converge, the ice is up to 900 metres thick.
