The physical area is made up for the most part of a high plateau formed by mountains, fields and valleys with an area of approximately 750 km². The average elevation is 1200 m (3937 ft), with Cristo Redentor, the highest point, at 1686 m (5531 ft). The topography is highly suggestive of a volcanic crater and, given that the region's rocks are indeed igneous and there are hot springs, this gave rise to a common misconception that Poços de Caldas would be located inside the crater of a large extinct volcano. In reality, Poços de Caldas is inside a caldera that was formed by the collapse of a central portion of terrain amid elevated areas, and while the latter have volcanic origin, the process that formed the supposed "crater" had nothing to do with volcanic activity.
