Heldenfingen Cliff

This cliff in Gerstetten displays a hollow carved by wave action in white Jurassic rock, marked by numerous holes created by boring mollusks and sponges. The formation rises prominently and clearly shows the marks left by ancient waves.

This formation originated about 15 million years ago as a rocky coast during the Tertiary period known as the Upper Marine Molasse. That ancient seacoast shaped what you see today at this location.

The Reef Museum in town displays fossils and materials explaining the ancient underwater world that once existed here. You can see what kinds of creatures lived in these waters millions of years ago.

A circular walking and cycling path called the Ancient Sea Trail begins at the cliff and extends about 14 kilometers. The route works well for both hikers and cyclists exploring the surrounding area.

A geological educational playground sits directly at the cliff and offers learning activities for visitors of all ages. The site blends recreation with hands-on science education right at this ancient shoreline.
