Tips from the Community
Edwin, I've been drinking water from that spring for over 30 years. In fact, all of us in Berriz drink water from the springs in Oiz. I'd say it's some of the best water you can drink in the Basque Country, hehe.

The municipality of Gautegiz-Arteaga preserves the only tidal flour mill that once existed on the Urdaibai estuary: the Ozollo Errota tidal mill. Furthermore, the Arteaga mill is the best preserved and the only one that retains most of its facilities. The mill was built around 1683, in the marshland of Laida Beach, in the Kanala area. An area of the marsh was used for its construction, enclosing it with walls, and it was fed by the dam in the rear reservoir. In addition to the milling house, where the drive wheels were installed, the mill has a building at the lowest point of the reservoir. This is a house located on the edge of the estuary, above the same water inlet and outlet. Therefore, the Ozollo Errota tidal mill is the most notable heritage structure in Urdaibai. The mill ceased to operate in the early decades of the 20th century and has been privately owned for several years.

The castle of Arteaga, also known as the castle of Empress Eugenia de Montijo, was built in the 19th century in neo-medieval style on the foundations of an 8th century castle. Its location stands out, in a large flat meadow surrounded by vegetation, unlike the medieval defensive castles built on a hill.

There is a fountain here and the views are quite good of the valley below. I'm not sure if the water is drinkable. It probably is, but I'm not sure I'd risk it.

Navárniz is at the foot of Mount Iluntzar. It stands at around 360 meters above sea level, making it high enough to have great views of the valley and mountains. It is a beautiful little town that is a good place to start an excursion.

This trail is wonderful but difficult. At some points it is very steep with many large stones. If you're going down, it may be more fun than trying to climb it. This is true singletrack and requires a good bike and strong legs.
