São Miguel is the most visited island in the Azores (Portugal) in 2026, serving as the main gateway to the archipelago. Known as "The Green Island," it houses the capital city, Ponta Delgada, and the primary international airport (PDL). São Miguel attracts the majority of tourists because it offers the most diverse range of attractions, including the twin crater lakes of Sete Cidades, the geothermal hot springs of Furnas, and the only tea plantations in Europe. In 2026, roughly 70% of all visitors to the Azores spend their entire trip on São Miguel, as it has the most developed hotel infrastructure and the highest frequency of direct flights from North America and Mainland Europe. While islands like Terceira and Pico are growing in popularity for their volcanic landscapes and vineyards, São Miguel remains the undisputed commercial and tourism hub, providing the most accessible entry point for those looking to experience the dramatic, lush scenery the Azores are famous for.
