Aletsch Glacier Tour: A 6-Day alpine expedition across Swiss glaciers

We set off early to reach Oberaarsee, then begin our first glacier trek up the Oberaar glacier. As we approach the Oberaar pass (3,231 m), the view opens out onto an impressive world of mineral and glacial landscapes.

The arrival at the Oberaarjoch hut (3,258 m) offers an exceptional panorama of the Fiesch glacier. Depending on the conditions and the mood of the group, we can attempt to climb the Oberaarhorn (3,631 m, +2h round trip) before enjoying an evening perched high up.

We start the day with a technical descent via the Galmihorn glacier, joining the immense Fiesch glacier, a veritable desert of ice stretching for several kilometres. The ascent of the Grünhornlücke pass (3,286 m) takes us to the Grüneggfirn glacier, revealing one of the finest panoramas in the Bernese Oberland.

We reach Konkordiaplatz, a veritable glacial crossroads where the biggest glaciers in the massif converge. To reach the Konkordia hut (2,850 m), we climb the vertiginous metal staircases, lengthened every year by the retreat of the glacier, a sign of global warming.

We cross the vast glacial plateau of Konkordiaplatz, where the Aletsch, Jungfraufirn and Ewigschneefäld glaciers join to form one of the largest ice fields in the Alps.

Under our crampons, more than 1,000 metres of ice slowly advance, sculpting the landscape for millennia. We make our way to the Lötschenlücke pass (3,170 m), where the Hollandia hut (3,240 m) nestles, offering an exceptional view of the Lötschental valley and its mythical peaks.

Optional morning ascent of Ebnefluh (3,962 m), a peak dominating the entire Oberland massif, offering an exceptional panorama of the Alpine chain. A demanding climb, but without any technical difficulties, for those wishing to extend their adventure at altitude.

We then begin a long descent via the Hollandia hut, then onto the Langg glacier, crossing alpine meadows and larch forests to Fafleralp (1,788 m), a small village nestling at the foot of the great north faces of the Breithorn, Schinhorn and Bietschorn.

After several days at altitude, a well-deserved evening of relaxation awaits us.

The final day of this exceptional journey. We begin our ascent of the Petersgrat (3,126 m), a vast snow dome marking the natural border between the Bernese Oberland and the Lötschental.

From the summit, the view of the north faces of the Breithorn and Bietschorn is breathtaking. We begin a gentle descent on the glacier, before reaching the Mutthorn Hütte (2898 m) for a final break at altitude.

The final descent takes us to Stechelberg, where the contrast between the green meadows and the hanging glaciers is striking. After a final meal, we take the post bus and then the train to Interlaken, where this unforgettable adventure comes to an end.
