The commune is situated in the Massif Central in Aubrac. Its inhabitants are called the Caldaguès, from the Latin meaning 'hot waters', or in French, eaux chaudes; hence the name of the commune, Chaudes-Aigues
As its name suggests, there are thirty natural hot water sources with temperatures ranging from 45° to more than 80°. The most famous is the source of the Par river with a water temperature of 82° - the hottest in Europe - with a flow in the region of 450,000 litres a day. One local story suggests that the source is so-named because a pig was dressed (paré) or jointed thanks to the hot water. The waters are used all year round. In winter, they have provided heat for houses and the church as district heating since the 14th Century; from spring the waters are channeled to the spa for the treatment of rheumatics.
The Remontalou crosses the commune.

During Roman times, warm water was circulated through open trenches to provide heating for buildings and baths in Pompeii.
