text: Geography Saint-Jean-de-Luz is a fishing port on the Basque coast and now a famous resort, known for its architecture, sandy bay, the quality of the light and the cuisine. The town is located south of Biarritz, on the right bank of the river Nivelle (French for Urdazuri) opposite to Ciboure. The port lies on the estuary just before the river joins the ocean. The summit of Larrun is about  south-east of the town. The summit can be reached by the Petit train de la Rhune, which starts from the Col de Saint-Ignace,  east of the town on the D4 road to Sare. It is in the traditional province of Lapurdi of the Basque Country.
  Saint-Jean-de-Luz bay is a natural harbour in the south-east of the Bay of Biscay. It is the only sheltered bay between Arcachon and Spain. Thanks to its strong sea walls or dykes that protect the town from the full savagery of the Atlantic Ocean, it has become a favorite for bathers across the Basque Coast. Although the seaside resort is relatively recent, the port itself is centuries old, with the most prominent point in its history being the marriage in 1660 of Louis XIV and the Spanish princess Maria Teresa.
  Water from the area flows into the town from the Nivelle and its smaller tributaries, the Etxeberri, Isaka and Xantako streams. There is also the Basarun, and its smaller tributary the Mendi, which passes directly through Saint-Jean-de-Luz. The river has been made accessible to boats and it joins the sea by the Erromardia beach. A branch of the Uhabia, an emblematic river in the neighbouring Bidart district, and its smaller Amisola tributary, also pass to the sea through St Jean de Luz.
