  description: Doniños is Galicia's intimidating jewel—a heavy beachbreak that produces some of the region's most powerful waves when large Atlantic swells arrive. The wave can be genuinely scary on big days, with thick lips and grinding barrels that demand respect and experience. The setting is dramatically beautiful, with rugged cliffs and a wild coastline that feels far from civilization. This is not a beginner spot, but for capable surfers seeking uncrowded, powerful waves in a stunning environment, Doniños delivers.
