Pico do Itacolomi, Mountain peak in Ouro Preto and Mariana, Brazil.

Pico do Itacolomi is a mountain peak on the border between the municipalities of Ouro Preto and Mariana in the state of Minas Gerais, Brazil. It sits inside Itacolomi State Park, a protected area covered with dense forest, rocky outcrops, and small streams running through the terrain.

The peak served as a landmark for early European explorers in the 17th and 18th centuries, helping them find their way through the rough interior of what is now Minas Gerais. Its proximity to the gold deposits around Ouro Preto meant that the area around its base became settled as mining activity grew.

The name comes from Tupi: itá (stone) plus kunumĩ (boy), meaning "stone boy". Indigenous people saw the peak as the mountain's child, since a larger rock stands with a smaller one beside it. The northeast face is visible from the historic centre of Mariana.

A marked trail through the park leads up toward the summit, and most walkers take around two to three hours to reach the top depending on their pace. Starting early in the morning gives you clearer skies and cooler temperatures before the midday heat sets in.

The peak's name means "stone boy" in Tupi, from itá (stone) and kunumĩ (boy): a larger rock with a smaller one beside it, read by indigenous peoples as the mountain's child. The orchid Habenaria itacolumia, endemic to the region, was long given up as extinct before being found again. The extinct Rede Tupi named its local station TV Itacolomi after the peak.
