Valserine Natural Bridges are located in the site of Perte de la Valserine (loss of Valserine) in Ain department of France near the town of "Belgarde-sur-Valserine". Here, the overflow of Valserine River has formed a myriad of potholes in a large strech of slabs. Some of these outstanding potholes have an perforated partiton creating arch and bridge. One of these percied pothole can be seen in the background of the photo.
