Lagoa das Sete Cidades

Lagoa das Sete Cidades was formed by successive collapses of two reliefs that surround it. This lagoon has a diameter of about 5 km and the walls reach a maximum altitude of 400 meters. It is one of the largest collapsed craters in the archipelago. Its walls have, for the most part, very steep sidehills. Pico das Éguas is the highest point, with an altitude of 873 meters. The surroundings of the lagoon include an urban area, farm lands and forests filled with cryptomeria. Lagoa das Sete Cidades is the largest natural freshwater reservoir in the Azores, occupying a vast area of 4.35 square kilometers, with a depth of 33 meters.
