The Flysch Route

The eight kms of coastline separating the towns of Deba and Zumaia feature cliffs of geological interest and importance recognised world-wide.In the flysch, we can point out great events and cataclysms in Earth's history, including the last great extinction that occurred globally.Therefore, we should not be surprised that several strata are international reference points for the planet’s geological age.

This is why it is visited by geologists from around the world and was declared a ‘protected biotope’ by the Basque government in March 2010.The area covers a total area of 4,300 land and sea hectares, and is the fourth biotope in the Basque Autonomous Community.

The flysch is located 40 minutes from the shire of Goierri, since it is possible to reach almost anywhere in the Basque Country within a hour.
