The source of the river Lea is in Oiz mountain, and it ends in the marshes of the old sea mill called Maria Errota. On its journey it wets lands of great natural beauty and a low population density. Apart from being one of the cleanest rivers in Biscay, its water is drinkable in the whole of its length.

Who doesn't know the famous "Boga, Boga, Mariñela", a composition that has practically become the official anthem of these lands? In Lea Artibai we can find many styles of music in concerts that are organized as well as in musical events.

There is no town or neighbourhood, however small, that does not hold demonstrations and competitions of rural sport in its different forms during its festivities. During the year, in the festivities and celebrations of our villages, exhibitions of rural sports are organised, which are the signs of identity of our customs and culture, for the enjoyment of those attending.

Lea-Artibai's gastronomy is based on the freshest products of each season, both from land and from the sea. The orographic and social diversity of the Lea Artibai region has historically fostered the production of high-quality artisan agri-food products.
