São Miguel is the largest and most diverse island in the Azores archipelago. Known worldwide as the 'Green Island', it captivates with its active volcanic geology that manifests itself in spectacular calderas, fumaroles and thermal pools. From the iconic lagoons of Sete Cidades to the mystical valley of Furnas, the island is a sanctuary of biodiversity and dramatic landscapes. Its capital, Ponta Delgada, offers a cosmopolitan contrast with volcanic stone churches and a vibrant marina. It is the ultimate destination for ecotourism, adventure hiking and whale watching in the North Atlantic.
