A beautiful vantage point. If the season is right, there's also the opportunity to watch whales. The path further to Gaztelugatxe, however, requires pushing because it's very overgrown. We didn't go far, but turned around and drove back along the road.

Insane new paved road with beautiful turns and views on the coast. Renown for local bikers but not too busy with cars for us around lunchtime

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.

Urdaibai is an extraordinarily beautiful and varied natural space, which is why it was declared a Biosphere Reserve by UNESCO in 1984. Its heart is the Oka River that rises on Mount Oiz and transforms into an estuary upon reaching Mundaka, creating spectacular marshes full of life. We recommend you see them at different times of the day to be able to appreciate both low and high tide. But in addition to unique marshes, Urdaibai offers you some of the most beautiful and appreciated beaches in Euskadi, Laida, which constantly varies in shape and size or the spectacular Laga beach, located under the imposing Peñón de Ogoño, which many define as “the closest thing to paradise.”
