Playa de Aguiyón, Beach in Cuaña, Spain

Playa de Aguiyón is a shell-shaped pebble beach in the Asturian council of Cuaña, near Cartavio and Loza. It runs about 370–380 metres along the sea with an average width of some 20 metres, and its grey, medium-grain sand lies among pebbles. The western end is bounded by the Punta del Palo, and the beach has no services.

The cove lies in the Asturian council of Cuaña, beside Cartavio and near the hamlets of Loza and Villalocay, from which the dirt track to Torbas beach leads to the descent. The western limit is the Punta del Palo, a headland that shelters the shell-shaped pebbler. The E-9 coastal path from Viavélez to Ortiguera runs along the clifftop above it.

The beach lies off the village of Loza, in the parish of Cartavio, and is reached on foot by a dirt track that forks toward Torbas; the descent ends at the edge of a cliff. It has no services of any kind, and its use is very low. Underwater fishing and recreational angling are practised from its shore.

The beach is reached by following an unpaved path from the village of Loza that descends steeply toward the shore. The path can be muddy or slippery depending on recent weather, so sturdy footwear and steady footing are important for safe access.

At the top of the cliffs, this beach connects to the E-9 hiking path, one of Europe's marked long-distance coastal trails. This junction makes it a natural stopping point for walkers traveling between the nearby coastal towns.
