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.

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.

From here you will have splendid views of the famous hermitage and the winding path that leads to it.

Located on the spectacular cliffs of Cape Matxitxako between the municipalities of Bermeo and Bakio, the lighthouse offers panoramic views of the Cantabrian Sea. It is also a historical place, as it was the scene of several shipwrecks in the past and has a monument in memory of the sailors who died at sea.

There is a fountain here and the views are quite good of the valley below. I'm not sure if the water is drinkable. It probably is, but I'm not sure I'd risk it.
