Dive-site story
Located on the southern shore of the Überlinger See branch of Lake Constance, Steilwand Wallhausen offers one of the most dramatic vertical freshwater walls in Central Europe. Divers enter from the shore across a shallow ledge before reaching a sudden drop-off where sheer molasse rock faces plunge into the dark depths. Below the summer thermocline, water conditions stay cold and clear, revealing sculpted stone overhangs, fissures, and lake fauna adapted to low-light environments.
