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.

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.

With 344 meters of altitude, this mountainous foothills of Jata are located very close to San Miguel de Zumetxaga, between the towns of Bakio and Mungia. It is difficult to get good views from the summit, since it is all quite covered by a pine plantation. In it you can see a beautiful mailbox in the shape of a house on which it says Tollu, as this summit is also known.
