This walk takes the visitor to discover the lesser known areas of the Geopark: the Black Flysch of Deba. We will travel back 100 million years to the past, when the Bay of Biscay opened up, and we will see a wonderful underwater landscape: large coral reefs, deep submarine fans, earthquakes and special natural gems such as the Deba septareas.
