The archipelago of Azores have been considered for long to be among the most beautiful islands in the world, a true paradise for nature lovers with most stunning lakes and vast volcanic coastline.

Furnas village contains at least two lakes (called caldeiras), one which is younger, 6-km wide and one which is older and larger and also it is less topographically distinct. The eastern wall of the 500-m-deep lake of Furnas (Caldeira da Furnas) overlaps the western wall of the Povoaçao lake of Nordeste volcano. The volcanic activity of the Furnas volcano dates back about 100,000 years.
