Dive-site story
Marmorerasee is an alpine reservoir in Graubünden created by flooding the historic village of Marmorera in the mid-twentieth century. Divers descend through clear, chilly mountain water to explore remnants of stone walls, roads, and foundations from the submerged settlement. The high altitude requires specialized dive planning and strict thermal protection across all seasons.
