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 Roman necropolis is located very close to the highest point of the Sollube massif. Here they received the ashes of the cremated deceased from a nearby town, between the 1st and 3rd centuries AD. c.

At 684 meters high, this is the highest peak of the massif that bears its name. It is located on the left bank of the estuary. During the Civil War, the so-called Battle of Sollube took place on its slopes for eight days.

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.

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!

In this area you will find the Santimamiñe cave and very close to the painted Forest of Oma. In the cave there are paintings from the Magdalenian period of the Upper Paleolithic (13,000 BC). The paintings are of animals such as bison, horses, deer, goats, and brown bears. There is a 3D virtual tour available at the Visitor Center.
