Climbing the Normal Route via NW Flank
Take the Jungfraujoch railway to 3,454 m, Switzerland, then walk to the Monchsjochhutte and climb this broad glaciated summit in the heart of the Bernese Oberland. The Normal Route via the NW flank (PD) is glacier terrain with a short steeper finish. It is quiet compared with the Jungfrau and Monch despite sharing the same hut, which makes it a good acclimatisation objective before the Finsteraarhorn. Rope up for the crevassed glacier and watch cornices near the top. Budget two days for the outing, with the railway shortening the approach considerably.
