The Petit train de la Rhune is a metre gauge rack railway in France at the western end of the Pyrenees. It links the Col de Saint-Ignace, some 10 km (6.2 mi) to the east of Saint-Jean-de-Luz, to the summit of the La Rhune mountain. Although this summit lies on the border between France and Spain, the railway lies entirely within the French département of Pyrénées-Atlantiques.
