Zermatt is one of the most beautifull areas in the "Alps" especially for SkiMo you will love this area.  In the Tours section you find a few SkiMo trails that are not on the regular skislopes.  I recommend not using the regular skislopes walking uphill,  because the hazard of collisions with skiers.  During the dark the preparation of the skislopes taking place and therefore, danger of wirestrikes.
