Shore wreck dive on the Walensee between Mols and Walenstadt, where two preserved Ledi cargo wrecks sit off the lakeside steps above Mols. The site is a cold-water wreck day for experienced divers who are comfortable with depth, drysuits, and a deliberate compass-led approach along the lake bottom. It rewards slow, controlled diving rather than speed, and the underwater route is easier when you are used to Swiss-lake conditions.
