Galicia rewards travelers who get off the main roads — the Celtic sites, wine valleys, river canyons, and island nature reserves are all best reached with some local guidance. Organised tours range from multi-day food and wine itineraries along the Rías Baixas to day trips to the Cíes Islands or catamaran trips through the Ribeira Sacra gorges. Several small operators run intimate group tours led by people who've lived in the region for years.
