Peñarrubia Beach, Seaside beach in Somió, Spain.

Peñarrubia Beach is a sandy cove in the Somió parish of Gijón, reached by stairs from a parking area off the GI-2 road or by the El Rinconín–La Ñora coastal footpath. Cliffs surround it, keeping the sand in shade during the morning, and the seabed is rocky.

The beach has remained largely unchanged throughout Gijón's development as a major port city, preserving its natural rock formations across centuries. This stability reflects the original landscape character of the region.

Peñarrubia is known as a nudist beach, a use documented in Asturian and Catalan sources alike. Bathers share the cove with walkers on the El Rinconín–La Ñora coastal path, who pass above the sand on the cliff edge. In summer the beach has lifeguard cover and danger signs.

The beach is readily accessible and offers practical facilities including showers and waste bins for comfortable visits. Regular maintenance keeps the cove clean and welcoming.

The beach is used by nudists, a practice not mentioned in most guides. Its orientation keeps it in cliff shadow through the morning, and rockfalls have at times forced the access stairs to close. Showers, bins and summer lifeguard equipment are provided.
