We have walked several Caminos along the north coast of Spain and they all have been beautiful with stunning views. Yesterday we walked along a coastal path that was different from other ones we have seen.
The rock making up this coast is apparently softer than usual rocks and gets worn away by the ocean waves. This creates a rugged coastline with many inlets. Sometimes the rock wears through creating a short tunnel that then opens on the top creating a hole where the ocean waves come up. They call these “buffoons” or bufones. They make interesting sounds and when the tide is high and the ocean rough they shoot up water 10-20 feet in the air.
This article talks about this and Basque Country.
I had never heard of a Global Geopark before (in the article you posted the link to). That’s fascinating and beautiful.
Fabulous scenery.
