Around the Iffigsee via the Iffighore

A loop at the head of the Iffigtal valley, above Lenk: you start at Iffigenalp, climb over the Hoberg to the Iffighore, the highest point of the walk, then drop down to the Iffigsee lake and come back along the valley floor. SwitzerlandMobility gives 4 h 25 of walking time and rates the loop medium for both fitness and technique.

The first half climbs up to the summit; the second half comes back down past the lake. The whole trail lies inside the protected Gälte – Iffigen landscape, listed in the Federal Inventory of Landscapes. The elevation profile shows you where it gets steepest.

The same protected landscape also takes in the Lauenensee, which you pass on the Höhi-Wispile-Lauenensee hike. And to walk into Lenk, there is the Adelboden → Lenk stage.

Start and finish are in the same place, the Lenk, Iffigenalp bus stop, next to the Berghaus Iffigenalp. Check the next buses and plan your day before you set off. Looking for more in the area? See all hikes in the Bernese Oberland.

The story of the trail

What happened where you are going to walk, chapter by chapter.

  1. Summer at the Iffigsee, a lake near Lenk in the canton of Bern

    A loop at the head of the Iffigtal

    You start at 1,584 m at Iffigenalp and finish there too. In between: 10.9 km, plus 880 m of climbing and the same amount of descent according to SwitzerlandMobility, which gives 4 h 25 of walking time in either direction. The highest point, at 2,379 m, is the summit of the Iffighore.

    At the start there's the Berghaus Iffigenalp. The only other place to eat is at Groppi, at 1,751 m, on the way back, shortly before the finish, so bring something to drink. On the way, follow the signposts and check the conditions on the day.

  2. Summer at the Iffigsee, a lake near Lenk in the canton of Bern

    Over the Hoberg to the Iffighore

    The path leaves Iffigenalp, passes by the Iffigbach stream and close to Groppi, then climbs through the Hobergtäli and past the Chesseli. A little higher up it passes close to Ober Hoberg. On the back of the Hoberg grows an open larch and Swiss stone pine forest, a rarity in the northern Alps, where the treeline has been barely touched by people.

    Plenty of edelweiss grow beside the path just past the last birches and stone pines of the Hoberg: stay on the trail and leave the flowers alone. The path then reaches the summit of the Iffighore, halfway round. From up there, the view stretches over the Simmental and the Saanenland.

  3. Summer at the Iffigsee, a lake near Lenk in the canton of Bern

    A lake that drains underground

    From the Iffighore, the path drops through the Heideloch gully to the shore of the Iffigsee. It is one of the karst lakes of the area: it drains underground. The two streams of the Iffigtal are fed by karst springs and do not flow all year round.

    Underfoot, wherever bedrock shows, you walk mostly on two layers of the Wildhorn nappe: Schrattenkalk limestone from the Early Cretaceous, and the sandstone and marl of the Tierberg Member, from the Eocene. Elsewhere you walk on alluvium, moraine, rockfall debris, scree and torrent deposits. Schrattenkalk takes its name from "Schratte", the German word for limestone pavement: it forms pale cliffs or surfaces carved by karst. The Tierberg Member is named after the Tierberg, in Lenk.

  4. Summer at the Iffigsee, a lake near Lenk in the canton of Bern

    Herders, Roman roof tiles and the Rawil

    Pollen and plant remains in the sediments of the Iffigsee show that animals were already grazed around the lake from the 5th millennium BC. Roman roof tiles found at the Iffigsee suggest a building, perhaps a shelter or a sanctuary. At Iffigenalp there are remains too: sections of road and a lime kiln.

    The Rawil Pass, leading to Valais, was already used for north-south traffic in antiquity. Until the Lötschberg railway opened in 1913, muleteers crossed it to bring in wine and sell cattle. A road tunnel under the Rawil, with its north portal at Iffigenalp, was planned and then dropped in 1986 by a federal decree.

  5. Summer at the Iffigsee, a lake near Lenk in the canton of Bern

    Back along the valley floor

    After the lake, the path goes back through the Hobergtäli, passes near the Egge, then drops to Groppi, and via Schwand-Rei back to Iffigenalp. This return through the Iffigtal is rough as far as Groppi, covered with loose stones: take hiking poles. The alpine columbine grows in large stands in the Iffigtal.

    At Iffigenalp, the bus takes you down to Lenk. The bus leaves from Lenk station and only runs at certain times of the year; from the Hubelmatte stop the road is one-way, with uphill and downhill traffic taking turns depending on the time. Further down this page: the next departures.
