Oropesa del Mar is a resort town on the Castellón coast, and one pairing defines it. It is far more international than either Benicàssim or Peñíscola, with about two in five residents holding a foreign nationality, yet its average asking price per square metre in July 2026 was lower than in both. It also contains Marina d'Or, a district whose price history is a lesson in its own right.
The annual census counted 12,483 residents at the start of 2025. The foreign population is broad rather than dominated by any one country: Romanians and Moroccans are the two largest communities, followed by Colombians, Ukrainians and Algerians, with Italians and Russians close behind. For everyday life the town has its own railway station on Cercanías line C6 and seven registered education centres, six of them public.
Idealista's July 2026 report shows the municipal average up by about an eighth over the year, but the longer view is sobering. The town still sits more than a quarter below its September 2007 record, and Marina d'Or remains about a third below a peak set in December 2007, nearly twenty years ago. Five of the six listed districts carry a published price, Zona Centro does not, and every annual figure spans Idealista's July 2026 methodology change.
