Falaise des vaches noires, Coastal cliff system in Gonneville-sur-Mer, France.
The Falaise des Vaches Noires extends for several kilometers along the Normandy coast with distinct gray and white limestone formations reaching about 100 meters in height. These cliffs display clear layers of clay, marl, chalk, and sediments that are visible throughout their structure.
These cliffs formed about 150 million years ago during the Jurassic period through marine deposits and contain numerous dinosaur fossils. This geological formation preserved traces of ancient sea life and prehistoric creatures in its layers.
The site draws people interested in geology and fossil hunting who come to study marine remains and prehistoric finds. Visitors notice how this natural repository helps people connect with ancient life forms preserved in stone.
Access to the cliffs is only possible at low tide from the beach, as climbing is restricted to protect the fragile rock structure. Visitors should check tide times and wear sturdy shoes to safely walk across the wet sand.
Erosion patterns have created parallel ravines separated by tall limestone spires, a geological formation found nowhere else on French coasts. This unusual structure developed through how water and time shaped the layers in a specific way.
