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.
The glacier formed long ago through the accumulation of snow and ice on the mountain plateau and has retreated significantly since the 20th century due to climate and weather patterns. The region also witnessed two tragic aircraft accidents in 1952 and 2015 that highlighted the dangers of the high alpine environment.
The glacier's name reflects its geographic setting and features prominently in local mountain narratives. Visitors can observe how this location serves as a reference point for climbers and hikers, and how the community views the alpine landscape as integral to the region's identity.
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.
The location is known for the strong Guggi Foehn, a katabatic wind that flows down from the glacier and produces noticeable cooling even in summer. Visitors can sometimes observe how this wind makes the ice flutter and creates characteristic cracking and rushing sounds.
