Sheltered quarry lake with strong training support.
Sheltered quarry lake with strong training support.
Hunsfels is a former lime mining site that has transformed into a lake covering approximately five hectares, with depths reaching up to 54 meters. The site features five distinct dive areas, each providing excellent visibility, typically exceeding 10 meters. The shallow regions are characterized by an abundance of aquatic vegetation and serve as a habitat for various juvenile fish species, including perch, pike-perch, and trout. 5mm suit necessary. Fed by underwater spring keeps it very cold at depth all year, but reasonably warm at the surface late summer.

Scuba Diving
The lake offers five dive sites and reaches a maximum depth of about 54 m.
Freediving
Freediving is possible in the sheltered shallows for trained cold-water breath-hold divers, but the site is better known for scuba training and exploration.
Snorkeling
Not a casual snorkel spot; the quarry is better for divers because the deeper layout and cold water make the surface-only experience limited.
