Guggi glacier, glacier in Lauterbrunnen in the Bernese Alps in Switzerland

Guggi glacier is a hanging glacier in the Bernese Alps that presents a striking appearance as it clings to steep mountainsides and descends from higher elevations. The glacier occupies a deep hollow between the mountains, measures roughly 500 meters (1,640 feet) wide and extends about 1.8 kilometers (1.1 miles) in length, with blue and white ice creating a strong contrast against the surrounding rock walls.

On 7 March 1952 a US Air Force C-47 Dakota crashed on the Guggi glacier, killing eight people and triggering a large rescue operation. On 13 July 2015 an Air-Glaciers Eurocopter AS 350 came down on the ice and its pilot died. The glacier itself is fed by ice avalanches from the Jungfraujoch at 3500 m and by the west flank of the Mönch.

The Guggi-Föhn is the local name for the wind that blows from the south over the Jungfraujoch and falls onto the glacier. It is known above all as a spoiler of the Lauberhorn downhill race, where it can disrupt the course and the racers' runs.

Access is via the village of Lauterbrunnen by train or cable car, from where visitors can hike or use mountain vehicles to ascend and explore the area. Summer offers the best conditions with milder temperatures, while winter becomes very challenging due to snow and ice masses and is suitable only for experienced mountaineers.
