Introduction to Sete Cidades
Sete Cidades, meaning ‘Seven Cities’, lies in the western reaches of São Miguel. This iconic site consists of an immense volcanic caldera spanning over 5 kilometers in diameter, sheltering two closely linked lakes: the Blue Lake (Lagoa Azul) and the Green Lake (Lagoa Verde). Encircled by forested crater walls and dramatic cliffs, Sete Cidades is both a scientific curiosity and the subject of centuries-old myths.
The Caldera and Twin Lakes
The centerpiece of Sete Cidades is its twin lakes—Lagoa Azul and Lagoa Verde—which are joined by a narrow channel across which a low bridge stands. Despite appearing to form two distinct bodies of water, they are in fact segments of one vast lake, with their differing hues resulting from light reflections and subtle variations in depth and vegetation. At 4 kilometers long and 2 kilometers wide, this is the largest freshwater reservoir in the Azores, and one of its Seven Natural Wonders.
Origins and Name
The name ‘Sete Cidades’ hearkens back to legends of lost islands and vanished civilizations said to exist in the Atlantic. Mariners told tales of Antília, or the Isle of Seven Cities, spurring searches for mythical lands. Locally, the lakes are entwined with the poignant legend of a forbidden love between a blue-eyed shepherd and a green-eyed princess—a story that, according to lore, gave rise to the lakes’ distinctive colors through their eternal tears.
Unmissable Viewpoints
One of the greatest pleasures of Sete Cidades is taking in the landscape from its spectacular ridges. The viewpoints—known as miradouros—offer sweeping panoramas and are must-visit stops for photographers, hikers, and anyone seeking the full impact of the caldera’s scale.
- Miradouro da Boca do Inferno: Arguably the most famous viewpoint in the Azores, Boca do Inferno unveils the entirety of the caldera, both lakes, and surrounding mountains. The walking path here traverses lush meadows to a dramatic promontory offering postcard-perfect views.
- Vista do Rei: Named for the visit of King Carlos I in 1901, this classic bunker-like viewpoint provides an iconic panorama of the twin lakes and the village below. Its accessibility and adjacent parking make it popular for all visitors.
- Lagoa do Canário: Another lesser-known but equally captivating spot, with tranquil lake and woodland settings, ideal for reflection and close encounters with local flora.
- Miradouro das Cumeeiras: Located on the crater’s northern rim, this viewpoint gives a unique perspective and is more secluded.
