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.

A small chapel that marks the peak of Bizkargi at 557 meters. Beautiful views on a clear day.

Small hermitage located on a hill at 791 meters above sea level, near the top of Monte Oiz. It is a place of great devotion and tradition, and offers stunning panoramic views of the surrounding valleys and mountains.

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.

This bridge is an incredible find in the middle of the forest. It is covered with ivy and in summer it is so green that it is hardly visible. If you go down next to the river you can take some great photos with the water and the bridge. For many years this bridge has had to survive numerous floods. It's amazing that he's still here.

Nice trail along the edge of a tree farm. It can get overgrown at times and when wet it can be difficult, but overall a good trail.
