Haute Route, Chamonix–Zermatt

The Haute Route does not so much connect Chamonix and Zermatt as thread a line between the two mountains that define the western Alps: Mont Blanc at your back on the first morning, the Matterhorn drawing you forward for a week until it finally stands clear above Zermatt. Between them lies a country of glaciated cols, moraine and high stone huts, crossed by generations of alpinists who treated this as the graduation walk of the range. There are two ways to travel it, and they are almost different journeys. In spring the classic is skied on touring gear, skinning up in the cold of early morning and descending glacier bowls in the afternoon, a rhythm of effort and reward that lasts six days. In high summer the same terrain is walked, roped across the flatter glaciers, with the rock scrambles of the passes taking the place of the ski descents. Either way you sleep in Swiss Alpine Club refuges perched at two and a half or three thousand metres, sharing dormitories, soup and the next day's weather forecast with strangers who quickly stop being strangers. This is not a trail you improvise. The route crosses crevassed glaciers where a rope, a harness and the knowledge to use them are not optional, and a qualified mountain guide is the norm rather than a luxury. Altitude sits with you throughout; the cols rise well above three thousand metres and the body notices. What you carry, quite apart from the pack, is a week of sustained concentration in serious terrain. What you take home is harder to name. The Alps seen from their own high passes are not the Alps of the valley postcards. You watch the Matterhorn change shape hour by hour as you circle towards it, you learn to read a glacier and to trust a rope team, and you arrive in Zermatt having earned the town rather than merely reached it. Done with the right preparation and the right people, it is the line every serious walker eventually wants to draw across the map.
