Lake Constance

Lake Constance offers a unique and challenging diving experience, distinct from any tropical destination. Nestled in the Alps, this vast freshwater lake is renowned for its dramatic underwater landscapes, including sheer rock walls that plunge into the darkness and historically significant, well-preserved wrecks. The main attractions are not colorful reefs but the thrill of exploring deep, cold, and clear waters, discovering artifacts from centuries past, and appreciating the stark beauty of an alpine underwater environment.

Diving conditions are demanding, with water temperatures dropping to a constant 4-6°C below the thermocline year-round, making drysuits a necessity for most dives. Visibility varies, often being at its best during the colder winter months. Divers should visit Lake Constance, Germany for its exceptional wreck diving, particularly the famous paddle steamer 'Jura,' and the opportunity to develop their cold-water and deep-diving skills in a stunningly scenic European location with excellent shore-side infrastructure.
