October 8, 2024, Old Tree of Gernika (Gernikako Arbola)

When the Condor attacked, the residents of Guernica tried to protect the tree with their bodies because it is sacred to the Basques. Even today, elected politicians have to swear their loyalty to the Basque Country at an oak tree that stands a few meters away.

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.

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

The work is planned so that an open point in the walls becomes a window from which one can see the Gernika tree.

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 little section of the trail has it all. There is a stream crossing, there is a nice climb or descent depending on the direction, there are great views, there are wide parts and narrow sections. It is a very nice trail for mountain biking.
