Caldeiras in Lagoa das Furnas is where Cozido das Furnas is made from secondary volcanism phenomena. There are currently 56 holes in activity linked to the confection of traditional stews, a part for the public and another for restaurants. One of the most interesting times of the day to visit the Caldeiras da Lagoa das Furnas is between noon and half-past noon, when those responsible for the restaurants go to the fumaroles to dig up their pots with the traditional Cozido das Furnas. This whole process starts very early when the pots are buried in holes built in the fumaroles. They remain buried for about 5 to 6 hours steaming.

Within this fumarolic field there is, with great prominence, the large fumarole named “Caldeira da Lagoa das Furnas”. Its temperature is approximately 98.5°C and acidic.
