In Guipúzcoa the mountains die into the sea, and the only open bends are the mouths of the rivers, where the towns were forged. With one exception, between Guetaria and Zarauz a promenade by the sea was created to unite the towns and today it is the most beautiful promenade in the area. 4 km smelling of the sea and, upon arrival, we will taste the famous Txakolí with the Getaria designation of origin.
