The municipality has an average annual median temperature of 21.2 °C and the vegetation is predominantly that of the South American Atlantic Forest. With 98% of the population living within the urban area, the city had two health facilities in 2009. The Human Development Index (HDI) of the municipality is 0.736, considered average in relation to the state.
The settlement of the municipality first began in the second half of the 19th century, with the construction of a stretch of the Estrada de Ferro Oeste de Minas railway. Notable features of the municipality include the handcrafts it produces and annual events such as the Carnival of Arantina.
The area of the current municipality first began to be settled during the 19th century, when the Estrada de Ferro Oeste de Minas (EFOM) railroad was being constructed. The railroad was intended to link the south of Goiás state with the Angra dos Reis municipality in Rio de Janeiro state, passing through Barra Mansa, RJ and operating both passenger and cargo trains. In Arantina there was a junction between the EFOM line and the Barra Line (the name is derived from Barra do Piraí municipality), connecting Bom Jardim de Minas municipality to the Barra Mansa line, now defunct.[2][3]
A small town emerged around the Arantes railway station, then situated in the municipality of Mantiqueira (today Bom Jardim de Minas). For several years the town that is today Arantina belonged to Bom Jardim de Minas. The town was known as Várzea do Paiol. In the current seat of the municipality there was a storehouse to store the corn harvested by farmer Juca Pereira, owner of much of the municipality's land.[4]
The town consolidated itself with the manufacturing of ceramics. Given the economic growth, by state law no. 1058 of 31 December 1943, the district of Bom Jardim de Minas was created, which received its name from the railway station. Arantina was emancipated by state law no. 2764 of 30 December 1962, being officially incorporated on 1 March 1963.[4]
According to the regional division of 2017, instituted by the IBGE,[7] the municipality belongs to the Immediate and Intermediate Geographic Region of Juiz de Fora.[8] Before this time, the municipality was included in the Microregion of Andrelândia and the Mesoregion of South and Southwest Minas.[9]

The terrain of the municipality of Arantina is predominantly hilly. Approximately 60% of the territory is covered in hilly areas, while about 30% is more mountainous, and the remaining 10% is generally flat. The highest elevation is 1,379 m found at the Serra do Caxambu and the lowest elevation is 1,030 m at the base level of the Capixingui stream in the Turvo Pequeno river. The central part of the town is at 1,050 m.[6]
The territory is covered in various small rivers and streams, principally the Capixingui stream and the Turvo Pequeno river, making up part of the Rio Grande river basin.[6] The Turvo Pequeno divides the municipality, and there are drainage projects for its sub-basin. Much of the water extracted from it is supplied to the towns of Arantina and Andrelândia.[10][11]

The vegetation of the town is divided into two classes of native ecological formations: the forest (Atlantic Forest) and the open clearings. Exotic vegetation and monocultures also occur. These classes, associated with the rugged topography, result in a diverse vegetation cover.[19] In the Atlantic Forest, trees such as the Tabebuia, Brazilian rosewood, angico, manacá-da-serra, Brazilian pine, and cedar stand out.[20]
