The Azores (Açores) are a chain of nine volcanic islands scattered across the mid-Atlantic, roughly 1,400 km west of mainland Portugal. Known for crater lakes, dramatic sea cliffs, thermal springs, and green pastureland, the archipelago offers whale watching, hiking, and diving in a landscape often compared to Ireland and Hawaii combined. Ponta Delgada, on São Miguel, is the archipelago's largest city and main gateway.
