Easy harbor-wall dive at the Kornhaus in Rorschach.
Kornhaus Rorschach is an easy Lake Constance shore dive by the historic granary and harbor wall. A line-linked underwater route leads past small wrecks, stone cover, and freshwater fish, with enough structure to stay interesting without feeling technical. The setup is best for compact teams that can keep the shore entry tidy and choose a calm day.

Key Hazards
Safety Notes
Cold-water exposure and a tight parking and harbor setup are the main practical risks; keep the shore kit compact and the buddy plan simple.
Access Restrictions
Not a big-group site. Limited parking and the narrow harbor approach make small, organized teams the best fit.
Legal Notes
Follow harbor and road rules, keep the small parking area clear, and check for any temporary lake or shipping advisories before entry.
Community notes to help plan your visit.
Scuba Diving
The underwater route is line-linked and uses several small wrecks plus orientation points, so it is easy to follow once you are in the water.
Freediving
Only the shallow approach is realistic for breath-hold use; the main route and wrecks are better suited to scuba.
Snorkeling
Snorkeling is limited to the entry shallows and surface look-around; the main features sit deeper than casual snorkel range.
