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.

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.”
