The limestone quarries near Klintholm are unusual geologic treasures. Fossilised shark’s teeth, brachiopods, sea lily stems and much more can be found here. The area has been designated as a National Geological area of interest in Denmark and also an international UNESCO Geosite.
In addition to the geological curiosities, the rare Fire-Bellied Toad lives in the old limestone quarries, waterholes and ponds.
