I’m just back from a short trip to Galicia, northwest Spain. One of the regions I visited was Ribeira Sacra, which is one of the most spectacular regions I’ve visited (and I’ve been to a few in my time). The steep slopes have been terraced, but even so, working these vineyards would require a good head for heights and sure footing! Here are some pictures.
