One of our favourite walks is up to the Cabane d'Arpitetta (2786m). The refuge is in a side valley at the bottom of the Weisshorn and is dwarfed by this 4500m peak. It's encircled by glaciers that spill down on every side adding to the scale of things. The refuge makes a great destination in itself and has a wonderful terrace for lunch with a view. Today the weather was really good so we decided to carry on up and across the Col de Milon (2990m) into the Tracuit valley.
It's a bit of a scramble and the north facing side is slippery (it's snow-bound for much of the summer) so we were grateful for the chains, but the views are stunning; it makes a wonderful - though long - round-walk from Zinal.
