The origin of Lagoa do Congro
Lagoa do Congro is located in the volcanic massif of Achada das Furnas, part of the Fogo and Furnas volcanoes. It actually is one of the most active seismic areas of the Azores.
The lake is in a crater of Maar type, which is a broad and low-relief volcanic crater resulting from a Phreatomagmatic eruption. This type of eruption means that the magma interacted with water, producing big explosions. It is believed that the lake was formed about 3.900 years ago.
Lagoa do Congro is quite different from the other lakes of São Miguel. Most of them are at the top of a volcanic cone, while Lagoa do Congro is in a relatively flat area, inside a hole and surrounded by a lot of vegetation.
The name comes from a tribute to the old owner of the lake, André Gonçalves Sampaio, also called ‘O Congro’. Congro – in English the European Conger – is a fish that lives in deep waters. When this former owner passed away, two more families owned the lake. They significantly changed the landscape, importing many exotic plants. This explains why most of the vegetation is not endemic.

Also note that the lakes of this area are get their water with torrential streams and three springs.
Fauna and flora of Lagoa do Congro
Lagoa do Congro is an area rich in biodiversity. About its flora, a lush forest surrounds the lake hiding the walls of the volcanic crater. Among the dense vegetation, you can mostly see Kahili ginger, Sweet pittosporum, Eucalyptus, Azalea, Cryptomeria, and hydrangeas blooming in the summertime.

It is a beautiful lake with water lilies, but the vegetation is quite wild so it looks more like a swamp. Most visitors of Lagoa do Congro will not even know that there is another lake close to it and very few people walk this path.
