Boca do Inferno is a popular viewpoint overlooking the crater lakes & village of Sete Cidades, on the Island of São Miguel in the Portuguese Azores. Sete Cidades is a village/parish located in the center of a massive volcanic crater 5 kilometres (3.1 mi) across, also referred to as Sete Cidades.
The Sete Cidades volcano/crater is situated on the extreme western portion of the island of São Miguel (Azores) occupying an area of approximately 110 km2 (42 sq mi). The last intra-calderan eruption occurred approximately 500 years A.D.
Presently, the interior of the structure is occupied by diverse volcanic structures and four lakes. The two crater lakes are referred to by the color of the waters: blue, reflecting the sky (Lagoa Azul) and green, reflecting the ground (Lagoa Verde).
