The wide, icy Rhone valley dominates the area. There are many side valleys off the main valley. At the head of the Mattertal valley is Zermatt, a pretty tourist village dominated by views of the Matterhorn (4,478 m). Fifty of the mountains are more than 4,000m high, with the highest, Monte Rosa, that reaches to 4,638m (15,217 ft), and there are many glaciers.
