In this small territory boxed in between the Cantabrian Sea and the Basque mountains, made up of the municipalities of MUTRIKU, DEBA and ZUMAIA, you’ll find 13km of cliffs belonging to the Basque Coast Geopark. Along them, you’ll find a spectacular formation of layers of rock called Flysch. The phenomenon is the result of the sea striking its rocks for 60 million years and creates a hypnotic landscape that your dog will enjoy during low tide.
