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.

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!

Urdaibai Bay is an important coastal biotope. The Spanish advertising advertises the region as a cycling region, ok without luggage and mountain bikes perhaps
