Zermatt is a starting point for hikes into the mountains, including the Haute Route that leads to Chamonix in France and the Patrouille des Glaciers. Cable cars and chair lifts carry skiers in the winter and hikers in the summer; the highest of them leads to the Klein Matterhorn at , a peak on the ridge between Breithorn and Matterhorn that offers extensive views in all directions. It is possible to cross into Italy via the Cervinia cable car station. A rack railway line (the Gornergratbahn, the highest open-air railway in Europe) runs up to the summit of the Gornergrat at 3,089 m (10,134 ft). Zermatt is also the western terminus for the Glacier Express rail service connecting to St. Moritz and the MGB (Matterhorn Gotthard Bahn).
