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.

From the lighthouse you have a 270° view on the coast, very clear on st juan de Gaztelugatxe, perfect spot for some scenic pictures!

Great view of the peninsula! In my opinion, you can save yourself the trip to the peninsula and the online registration process.

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.

The legend that attributes the name of Mundaca to the Latin expression munda aqua (clean water). This legend appears in the Chronicle of Vizcaya written by Lope García de Salazar in the 15th century. According to this story, a ship from Scotland arrived on the coast of Mundaca carrying a princess who had been banished from her land. The Scots called the place Munda aqua in their Latin language (sic) since they found a very clean source of water that contrasted with the murky waters of the Urdaibai estuary.
