Mantiqueira Mountains, mountain range of eastern Brazil. It rises abruptly from the northwestern bank of the Paraíba do Sul River and extends northeastward for approximately 200 miles (320 km), reaching a height of 9,255 feet (2,821 metres) in the Pico (peak) das Agulhas Negras.
The mountains, which eventually merge with the Espinhaço Mountains were originally forest-covered except for the peaks that rise above the tree line. They provide charcoal and pasture for cattle; on the lower slopes there are several health resorts, including Campos do Jordão. The name Mantiqueira derives from a Native American word meaning “the place where the clouds lie.”
