This is the ruins of an ancient Celtic town, on a dramatic cliff overlooking the water. Absolutely stunning, dramatic, and haunting! The views are amazing, the circular remains of the buildings are fascinating and create a rhythmic labyrinth among the beautiful eroded rocks. Please note that this is steep, slippery (particularly as it is usually either raining, or drizzling in this gorgeous part of Galicia), and terrain where you need footwear with some traction! It is well worth the climb.
