Beach of la Rubina Nature · Castelló d'Empúries, Alt Empordà, Girona La Rubina beach, also known as Wild Beach, is a natural beach in the municipality of Castelló d'Empúries situated within the Aiguamolls de l'Empordà Nature Park, between the Empuriabrava inlet and the Santa Margarida residential marina. It is 1,704 metres long and 59 metres wide, made up of medium and fine sand with a very steep slope into the water; at the end closest to Santa Margarida, dogs and kitesurfing are permitted. The Catalan Water Agency checks the quality of its waters weekly during the bathing season, with excellent results. Behind the beach stretches a dune belt with pools typical of a wetland, protected by a fence that shelters the vegetation and the wildlife that nests there, such as the Kentish plover.
