This dive site is the Schottensee, a high-altitude lake located directly at the top of the Flüela Pass in Switzerland, at 2374m above sea level. Known in Rhaeto-Romanic as Lai da la Scotta, the lake is approximately 400m long and 200m wide and belongs to the municipality of Zernez. Underwater navigation is straightforward due to its shallow depths (average 3m, max 7m) and clear shorelines. The Flüela Pass road runs along its eastern shore, providing easy access and orientation, making it a unique altitude diving experience.
As a cold, high-altitude alpine lake, the marine life primarily consists of hardy freshwater species. Divers might encounter various types of aquatic plants covering the lakebed in shallower areas. Depending on the season, small freshwater fish like trout or char, along with insect larvae and other invertebrates, could be observed. The environment is more characterized by its unique geological setting and specific flora rather than a rich diversity of large animal life.
The best time to visit Schottensee for diving would likely be during the warmer months of summer, typically July to September, when the Flüela Pass is open and water temperatures are at their highest, though still cold. Divers should be prepared for cold water conditions and are advised to use dry suits or thick wet suits. Due to its shallow depth, it's excellent for extended bottom times and ideal for altitude diving training. Both snorkelers and freedivers will find the site suitable for exploring the unique high-alpine underwater landscape and observing freshwater flora.
