The Bivouac du Dolent, perched on the east ridge of Mont Dolent in Valais, Switzerland, resembles a futuristic capsule hotel or lunar module. It serves as a stopover for alpinists tackling Mont Dolent via the Gallet ridge. The path up to the bivouac is narrow and steep, with some ladders and chains to assist climbers along the way. The bivouac offers stunning views of the Dolent glacier, Pointe Allobrogia, and Mont Grepillon, making it a unique destination for adventurous loners seeking solitude in the Swiss Alps.
