Lagoa das Sete Cidades is a stunning twin lake located in the Sete Cidades volcanic crater on the island of São Miguel, part of the Azores archipelago in Portugal. The lakes are known for their distinct colors: one is a vibrant blue, while the other is a rich green. This unique color difference is attributed to the varying mineral content and depth of the lakes. The area surrounding Lagoa das Sete Cidades is a popular destination for hiking, photography, and nature exploration. Visitors can enjoy breathtaking views from several viewpoints, such as Vista do Rei, which overlooks the lakes and the lush landscape of the crater.
