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.

This hexagonal-shaped hermitage from the 18th century was built because the previous one was in ruins. The three large rocks inside draw attention, holding each other together. Within these rocks is the figure of the Archangel Saint Michael.

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.

This is a small town of just a few houses with nice views and a small church. If you are mountain biking or touring the area, it may be worth stopping to take some pictures or just to rest.

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 is a terrific trail that is quite easy to follow. It is especially nice in spring when the flowers come out. It gets a bit wild in the summer when the vegetation is waist high, but that's part of the adventure!
