Platja de Castell, Sand and nude beach in Palamós, Spain

Platja de Castell is a sand and nude beach along the Costa Brava, featuring golden sand bordered by dense pine forests and farmland behind the shoreline. The beach stretches for several hundred meters with natural features largely undisturbed by development.

The small peninsula of El Castell, which gives the beach its name, holds the Iberian settlement of Castell, founded in the 6th century BC. In the late 1970s a marina was considered for the inner esplanade, and in the early 1990s the urban plan proposed 100 detached houses, a hotel, 180 more homes among the pines and even a golf course. A 1994 referendum in Palamós rejected the plan, later confirmed by the courts. In 2009 the Generalitat bought 40 hectares of the Castell plain for about 12 million euros.

The beach takes its name from the small peninsula of El Castell, crowned by the 6th-century BC Iberian settlement. On the right side, behind a group of rocks, nudism is practised. The beach also has a kayak school, and the riera de l'Aubi has flowed into the sand since its course was diverted in 1927.

Access is on foot via the camí de ronda from Platja de la Fosca, or by car on a track off the C-255 between Palamós and Palafrugell. Since 2019 the car park sits further from the sand. Ramps and boardwalks make the beach accessible for reduced mobility, and there are showers, a bar, sunbed and parasol rental, a kayak school and lifeguards in season.

The shore remains remarkably undeveloped with no high-rise construction, only old farmhouses and pine groves breaking the natural landscape. This absence of building keeps it among the few remaining untouched coastal stretches in the area.
