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.

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.

This cape is the most prominent point in Euskadi, located very close to the famous hermitage of San Juan de Gaztelugatxe. If you bring binoculars, you can also occasionally spot cetaceans and seabirds. In addition, you will be able to see the current lighthouse as well as the old one, although only the tower remains of the old one.
