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.

Edwin, I've been drinking water from that spring for over 30 years. In fact, all of us in Berriz drink water from the springs in Oiz. I'd say it's some of the best water you can drink in the Basque Country, hehe.

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.

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.
