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.

That is NOT A FOREST! It is a single plantation of eucalyptus. In reality it is a disaster painted green, green as hell.

Very nice stop! From the parking lot you have to get on your own feet and then hike to the hermitage but it's worth it!
