500k - the MAGIC Wallis/Valais area - no words can express the beauty of the Grimsel, Susten, Gothard and Nufenen pass as indicated on the map + do not forget the Furka Pass to be drawn right in the middle - Obergoms, at the very end of the Rhone valley, is nice place to stay, even if you do not know all people in this small village as my friend Piet does:)
