Sete Cidades Crater Lake
Lagoa das Sete Cidades, 9555, Portugal
Sete Cidades Crater LakeThis five-kilometer-wide, forest-covered, extinct volcanic cauldron hugs the green (Lagoa Verde) and blue (Lagoa Azul) lagoons and is visible from the Vista do Rei (King’s View) lookout. If the crater seems familiar, that's because it's the landscape depicted in countless postcard photos of the Azores. According to an ancient legend, the different colors of the lagoons are the result of one being formed from the tears of a shepherd and the other those of a princess with whom he shared a forbidden love. It's a much more romantic story than the scientific explanation: the different colored algae found in each.
