Zermatt was "discovered" by mid-nineteenth-century British mountaineers, most notably Edward Whymper, whose summit of the Matterhorn made the village famous. The Matterhorn was one of the last alpine mountains to be summitted (in 1865), and the first expedition that reached the top ended dramatically with only 3 of the 7 climbers surviving the descent. The story is related in the Matterhorn Museum. 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 3,883 m (12,740 ft), 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. The year-round population is about 6,000, though there may be several times as many tourists in Zermatt at any one time. Much of the local economy is based on tourism, with about half of the jobs in town in hotels or restaurants and just under half of all apartments are vacation apartments. Just over one-third of the permanent population was born in the town, while another third moved to Zermatt from outside Switzerland.
