Sollube, Mountain summit in Bermeo, Spain
Sollube is a mountain summit at 683 meters elevation that spans across several municipalities in northern Spain and dominates the landscape of the Basque region. From its location, visitors can see the coastline and surrounding terrain clearly.
The Battle of Sollube occurred in 1937 on its slopes during the Spanish Civil War as a key confrontation between Italian troops and Republican forces. This conflict marked the mountain as a historic battleground.
The mountain is one of five horn peaks in Biscay that served as signaling points during traditional General Assemblies through horns and lights. Today it remains a symbol of how communities historically communicated across the landscape.
The main route climbs from Alto de Sollube pass at 384 meters via a paved track to the summit, while several hiking trails offer alternative ways up. Wear sturdy footwear and check weather conditions before visiting, as conditions at the top can change quickly.
The mountain marks the natural boundary of the Urdaibai Biosphere Reserve and offers sweeping views of the entire estuary from its summit. This position makes it a key vantage point for understanding the local environment.
