Kreidesee Hemmoor: shore quarry with wreck routes and clear water
Kreidesee Hemmoor is a flooded chalk quarry with multiple shore entries, a clear freshwater body, and route-based diving built around wrecks, walls, platforms, and training features. It mixes easy shallow attractions with deeper sections, so divers should choose an entry point and plan the route before dropping in. The site rewards cold-water discipline, buoyancy control, and a buddy plan more than raw speed or current management.

Not a snorkel site; the main attractions sit well below practical snorkel depth.
