On 18 June 1917, Arnold Lunn, a pioneer ski mountaineer, and Josef Knubel of St. Niklaus in the canton Valais made the first ski ascent of the Dom, by the Hohberg Glacier (north flank). Climbing routes and huts Climbing the Dom by its normal route is a relatively straightforward, but nevertheless long and somewhat arduous 3,100-metre ascent on foot from the valley, and taking 6 hours to the summit from the Dom Hut. The route is graded as PD- on the French adjectival climbing scale. This route has been described in the mountaineering literature as "something of a snow trudge". The only mechanical means of access is located in the Saas-Fee area, on the east side of the mountain, from which all the routes to the Dom are much harder. The easiest way to the summit starts from Randa, where there is a railway station (1,407 m) served by the Matterhorn Gotthard Bahn. From Randa a trail leads to the Dom Hut (2,940 m), which also crosses the Europaweg near the Europa Hut. Climbing the mountain requires an overnight stay at the Dom Hut. The normal route starts from the hut and goes on the Festigletscher glacier towards the Festijoch (3,720 m). It then follows the Hohberggletscher glacier to the summit above the north face. An alternative route is provided by the Festigrat, which is the Dom's north-western ridge. It goes directly from the Festijoch to the summit, and is preferred by climbers who wish to avoid the long slopes of the north flank. In good conditions it is graded at PD/PD+. However, its upper section can be treacherous in icy conditions, in which case the north flank approach is better. Domgrat The summit of the Dom can also be reached from the south by the classic and exposed 'Täsch-Dom traverse'. This is a very long, committing and challenging mountaineering route which has been described as "one of the most demanding ridge grandes courses in the Alps". This route (via the south ridge or Domgrat), first requires an ascent of the adjacent Täschhorn - most easily attained from the Mischabel Bivouac Hut perched on Mishabeljoch. From there, an ascent of the Täschhorn's south-southeast ridge (Mischabelgrat, grade AD, III) is made in 4 to 5 hours. The descent from the Täschhorn to the Domjoch (4,282m) is on steep, slabby and sometimes icy rock, taking 2–3 hours, followed by a further 2–3
