Playas de Entremares y de Buelna, Coastal beaches in Llanes, Spain

Playas de Entremares y de Buelna are two small coves nestled between rocky cliffs with fine sandy floors that change shape with the tides. The shoreline features distinctive limestone rock formations that rise from the water and create a dramatic coastal profile.

These coves were carved by natural erosion processes as the sea cut into limestone bedrock over extended periods. The resulting rock formations adapted to tidal cycles, and their shape remains constantly shaped by wave action.

The name Entremares refers to the cove's position between tides: it vanishes at high water and reappears as the sea drops. Neither beach has any facility beyond litter bins and a cleaning service, so bathers arrive self-sufficient. The two coves join into one shoreline only during the largest low tides.

Both beaches are accessible via marked paths from the village of Llanes and are best explored at low tide when more sandy area is revealed. Visitors should monitor tidal schedules since the walkable area varies significantly depending on water levels.

The two beaches are separate except at low tide, when they join and the limestone pinnacle El Picón at the end of Buelna becomes reachable. The same stretch of coast also holds blowholes, lapies and dolines, karst features that visitors often overlook.
