Freshwater bunker dive on Lake Constance
Freshwater bunker dive on Lake Constance
Immenstaad - Bunker is a freshwater wreck-style dive on Lake Constance, built around a blown-up torpedo test facility with metal struts and openings that give it a strong lost-place feel. The site suits careful scuba divers who are comfortable with low visibility and close-range navigation, and it rewards tidy buoyancy with carp and other lake fish moving through the structure. It is more about controlled exploration than about open-water scenery.

Scuba Diving
Best for careful freshwater wreck diving, with the interior reserved for experienced wreck or cave divers and the exterior suitable for a more conservative profile.
Freediving
Not a freedive-first site; the structure, openings, and low visibility make scuba control the better fit.
Snorkeling
Snorkeling is not the point here; the attraction is the submerged bunker and its surrounding structure.
