A very pleasant little village with a beautiful castle. A visit inside is highly recommended; they store your bikes in the courtyard :)

It is a beautiful circuit from the campsite to the Castillo de Javier. There are a few climbs to be overcome by bike, but when you reach your destination you can enjoy the castle, which is still run by nuns - the Pope has also been there.

The Castle of Xavier, built in the 10th century, is located on a hill in the town of Xavier. I used this village for my overnight stay on my way to Santiago de Compostela. From my room I had a view over this Castle, something I can recommend.
