Águas de São Pedro is popular for its mineral waters, as its name indicates. There are three fountains in the municipality: "Fonte Juventude" (Youth Fountain), "Fonte Gioconda" ("Gioconda" Fountain), and "Fonte Almeida Salles" (Almeida Salles Fountain), all with a much higher mineralization than most other Brazilian mineral springs. Of these three, only the last two have a natural outcrop, as the "Juventude" fountain water comes from the artesian well at an old oil exploration site. The water in the "Fontanário Municipal" (Municipal Fountain) is potable, and for baths, there is the "Spa Thermal Dr. Octavio Moura Andrade", the municipal bath house.
