Playa de Guadamía, Natural beach in Llanes, Spain.

Playa de Guadamía is a small cove with fine sand backed by limestone cliffs that drop steeply to the water. The Guadamía River flows into the sea here, carving natural caves and rock formations along the shoreline.

The limestone cliffs formed when this area was beneath ancient seas millions of years ago. Water from the Guadamía River has continued to shape the caves and rock patterns we see today.

The beach's name appears in several forms: Guadamía is a Castilianized version of Aguamía, and it is also called L'Aguada. The Guadamía River marks the boundary between the municipalities of Llanes and Ribadesella. The surrounding cliffs contain caves and bufones, narrow vertical chimneys where seawater and air escape with a loud roar.

Access is via an old cart track from Llames de Pría, or on foot along two paths on the slope of Cuerres. The beach has no services apart from cleaning, so bring what you need. The irregular shoreline and surrounding cliffs mean you should watch your footing.

The cliffs around the cove are pierced by narrow vertical chimneys called bufones, where seawater and air are forced out in noisy bursts. The site is cited as a good place to study karst modelling, and the beach can be reached on foot by two paths down the slope of Cuerres.
