You won’t find salty seas in Switzerland, of course, but the alpine lakes and rivers here make for unique and mystical scuba diving.
Lake Geneva has a variety of dives to discover. Wall dives and bizarre freshwater scenery can be perused beneath the surface. There is even a wreck dive, a stellar spot for more advanced divers to take the plunge.
Another is Lake Zurich, where you can head to excellent scuba spots right from the shore. The lake is serenely set, with lofty mountains cascading upward from the lakeshore. Glacially fed, the lake has sublime visibility.
River divers will be blown away by the Verzasca, an impossibly clear river found just south of the Alps near the border of Italy.
Bear in mind that Switzerland becomes quite frigid in the winter, and if you plan to dive during the colder months you will need a wetsuit to brave the waters, often remaining only just above freezing.
