FLYSCH OF BISCAY

The extraordinary and unique coastline

The flysch route of Biscay, which runs through Getxo, Sopela, Barrika, Gorliz, Lemoiz and Bakio, offers curious phenomena of undeniable geological value. On Sopela’s accessible beaches, you can see the K/T limit, which is marked by the disappearance of the dinosaurs. There is a programme of guided tours of the cliffs with guaranteed departures for 6 months of the year.

Another important phenomenon are the Astondo Dunes in Gorliz, a rampant sandy formation due to the combined action of the sea and the north winds. The variety of fossil dunes, rocks 6,000 years old in which the sand is petrifying, has increased the value of this area.

Take your camera and wait for the tide to go out... if you are in Barrika, you will be amazed by the natural treasure that unfolds before your eyes. In this geological formation, you will find an endless number of animal and plant species: it is the tidal flats.

Remember that before you is a surprisingly beautiful natural phenomenon that you must respect and take care of, thus preserving this unique environment.

Views from the sea
