Konkordia Hütte: Front-Row Seat Above the Aletsch Glacier
The Great Aletsch Glacier is the largest glacier in the Alps — 23 kilometres long, up to 900 metres deep, covering an area of approximately 80 square kilometres in the UNESCO Jungfrau-Aletsch World Heritage Site. Standing at the Konkordiaplatz — the great junction where three tributary glaciers merge into the Aletsch's main trunk — and looking up toward the Jungfrau, Mönch, and Aletschhorn summit cluster is one of the great visual experiences available in European mountain travel.
And above it all, bolted to the cliff face on the eastern side of the Konkordiaplatz, is the Konkordia Hütte.
Getting there
The standard approach to the Konkordia Hütte is across the Aletsch Glacier itself, typically from the Jungfraujoch (3454 m), reached by the Jungfrau Railway — the highest railway station in Europe, carved inside the Eiger. From the Jungfraujoch, the descent onto the Jungfraufirn (the upper névé feeding the Aletsch) and the walk south toward the Konkordiaplatz takes 3–4 hours on firm glacier. Crampons and rope are required; crevasse hazard exists particularly in the lower sections where the glacier surface becomes more disturbed.
Alternative approaches include the Hollandiahütte route from the Lötschental side, crossing the Lötschenlücke (3178 m) and descending to the glacier — a demanding approach used for longer traverses of the Bernese Oberland. From the south, parties crossing from the Märjelensee or Bettmeralp area approach via the Aletsch Glacier itself, walking north up the ice.
All approaches require glacier equipment and experience. The Konkordia Hütte is not an objective for parties without prior glacier travel competence.
The ladders
The most celebrated — and for some guests, most alarming — feature of the Konkordia Hütte approach is the fixed-ladder access from the glacier to the hut. As the Aletsch Glacier has retreated over the past century, the vertical distance between the glacier surface and the rock ledge where the hut sits has increased dramatically. The ladders and fixed chains that provide access now cover approximately 150 metres of vertical cliff face — a sequence of steel rungs bolted directly into the schist.
In the 1970s, the glacier surface was close enough to the hut that the ladder section was a short scramble. By 2026, it is a sustained ascent requiring 30–40 minutes of careful climbing. With a pack, in crampons (which are removed before the ladders), in exposed conditions, this section concentrates the mind considerably.
The ladders are well maintained by the SAC Grindelwald section and are in good condition throughout the operating season. Fixed ropes alongside the ladders allow guests to clip in for additional security.
The hut and the UNESCO World Heritage context
The Konkordia Hütte accommodates approximately 100 guests and is open in summer (typically mid-June through early October) and during the spring ski- touring season. It sits directly above the confluence of the Jungfraufirn, Ewigschneefeld, and the main Aletsch glacier arms — the Konkordiaplatz — which at roughly 2700 m is the lowest point reachable on the glacier from the Jungfraujoch approach.
The Jungfrau-Aletsch UNESCO designation (added to the World Heritage list in 2001) recognises the area as the most glaciated region in the Alps and a site of outstanding geological and scenic significance. The glacier retreat visible from the Konkordia Hütte is one of the clearest demonstrations of climate change observable from a fixed point in the Alps: photographs from the same position across decades show a surface that has dropped by more than 100 metres.
Objectives from the hut
The Konkordia Hütte serves as base camp for several significant alpine objectives. The Aletschhorn (4193 m) is reached via the Mittelaletschgletscher — a serious glaciated approach rated PD/AD. The Gross Wannenhorn (3906 m) and Kleines Wannenhorn are also accessible, at lower technical grades.
For ski-touring parties, the Konkordia is a key stage in the Bernese Oberland traverse — the high-level ski route linking Grindelwald and the Lötschental via the Jungfraujoch and Aletsch system. This multi-day traverse involves glacier skiing of the highest order and is one of the great ski routes in Europe.
Glacier change and route updates
The Aletsch Glacier retreat has modified approach routes to the Konkordia Hütte significantly and continues to do so. Sections of the glacier that were straightforward in 2000 are now heavily crevassed or have disappeared entirely. The hut keeper maintains current route information and provides updates for parties approaching — consulting the hut before departure is strongly recommended, particularly in the early season (June) when seasonal changes are most significant.
UNESCO World Heritage designation
The Jungfrau-Aletsch area received UNESCO World Heritage status in 2001 — the first time the UNESCO committee awarded a heritage designation to an area of the Alps specifically for its glacial landscape character. The designation encompasses approximately 82,000 hectares of glaciated terrain, including the Great Aletsch Glacier, the Jungfrau (4158 m), Mönch (4107 m), and Eiger (3967 m), and the associated glacial valleys.
The Konkordia Hütte sits within the core of the World Heritage zone and is one of the few overnight options inside the UNESCO-designated area. The designation does not restrict hiking or hut access, but it creates a formal framework for conservation management and monitoring of the glacier system. The Swiss Federal Office for the Environment (BAFU) and the SAC collaborate on the management plan.
The irony of the UNESCO status is that the very feature it was designed to protect — the Aletsch Glacier itself — is retreating at a rate that makes the "world heritage" designation increasingly poignant. The glacier has lost over 3 km in length since 1870 and approximately 2 km since 2000. Current projections suggest the glacier will lose most of its current volume by 2100 under moderate emissions scenarios.
The approach ladder: logistics and condition
The 150-metre ladder system at the Konkordia Hütte is maintained by the SAC and is inspected annually before the season opens. The ladders are bolted into the rock face; fixed chains provide additional security at the more exposed sections. The ascent takes approximately 30–45 minutes, including stops on the intermediate platforms.
Parties with heavy packs — particularly ski-touring groups with ski boots and skis — should note that the ladders require careful management of equipment. Skis are typically carried vertically in a backpack frame or strapped across the pack; crampons and ski poles should be stowed before starting the ladder section. The hut keeper can provide specific advice on current ladder conditions when you confirm your reservation.
Booking and practical logistics
The Konkordia Hütte is reached by helicopter in the event of emergency but normal resupply and provisioning is by goods ropeway. The ropeway connects the hut to the valley below and reduces the helicopter dependency that characterises most remote high-Alpine huts. The hut is open from approximately late February (ski-touring season) through late September (summer walking season). Book through the SAC reservation system (sac-cas.ch); the hut fills quickly for peak-season weekends and the prime traverse dates in spring.
