Le Pont de la Reine (Queen Bridge) is not a true natural bridge but a huge fallen boulder eroded by river stream. It is not taken into account but it is so beautiful, he has a merit to appearing here. It is located on the lower Gorges de la Lyonne near the village of Saint-Martin-le-Colonel on Vercors Range in Drôme department of France. IGN topgraphic map # 3136 Combe Laval (pleat B5).
