Praia dos Castros is a pristine beach in the Ribadeo municipality of Lugo, known for its distinctive rocky formations and sea caves. It is interconnected with the neighboring Praia das Illas at low tide, creating a large, continuous sandy area. The beach is characterized by its dramatic cliffs and golden sand set against the Cantabrian Sea. It lacks significant tourist infrastructure, maintaining a raw, natural landscape. Swimming conditions vary significantly depending on the Cantabrian tides, which are notably strong in this region. The site is part of the protected coastline of the Mariña Lucense.

Bring sturdy footwear for navigating the rocky paths and slippery stone formations near the water.
Carry all necessary supplies, including water and food, as there are no amenities or shops directly on the beach.
Attempting to swim during high tide when currents become powerful and the beach width is minimal.
Practice 'leave no trace' principles; respect the fragile cliff ecosystems and local bird nesting sites.
