Mt Renge

Mt Renge (Japanese: 蓮華岳) is one of those North Alps peaks that feels both rugged and quietly beautiful. It sits on the other side of a saddle from Mt Harinoki (針ノ木岳) and is reached by the same demanding approach from Ogisawa. The climb is notable for the long ascent up the Harinoki snow valley, a steep, atmospheric corridor of lingering snow and towering rock walls. In early summer, the valley is still filled with hard snow and requires experience and snow climbing equipment. Even later in the season the route remains steep and rough and requires experience and physical strength.

​

Once you emerge from the snow valley and gain the ridge, the character of Mt. Renge changes completely. The ridge line is broad and rocky, the wind blows freely and hardy wildflowers cling to the thin soil. I especially enjoyed the contrast between the harsh climb below and the alpine scenery above. Clusters of  high‑altitude flowers brighten the stones, and raichō rock ptarmigans sometimes appear among the rocks.

​

The summit ridge offers wide, sweeping views across the southern part of the North Alps. You can trace the jagged skyline toward Tsurugi (剱岳) and Tateyama (立山), look back toward Harinoki, and see the deep valleys that carve the range into dramatic relief. 

​

Mt. Renge is a demanding hike, but well worth the effort. Its combination of steep snow valleys, rocky ridges, alpine flowers and big views makes it one of the most rewarding lesser‑known peaks in the North Alps.
