The lake is actually two lagoons, called Green Lake (Lagoa Verde) and Blue Lake (Lagoa Azul), linked by a shallow channel.
Look down into the Sete Cidades Crater to Sete Cidades Lake, Rasa Lake, Santiago Lake and the village.
The lake fills a small volcanic crater within the larger Sete Cidades Crater.
Once you’ve visited the attractions at Sete Cidades Lake, leave Sete Cidades village on the main road up the west side of the crater.
