Estrada Real Minas Gerais Diamond Mining Circuit

The cobblestone sections near Diamantina tell the real story — 300-year-old wagon ruts carved by Portuguese miners hauling fortune from the Serra do Espinhaço. This 280-kilometer circuit connects Ouro Preto to Diamantina via backroads that bypass the main BR highways, threading through abandoned mining camps and crossing the Rio das Velhas at shallow fords unchanged since colonial times. The technical challenge hits hardest at the Sempre-Vivas plateau crossing, where granite slabs demand careful tire placement and the altitude tops 1,400 meters.

Moderate to difficult depending on season — dry months (May-September) keep the creek crossings manageable, but summer rains turn clay sections into wheel-sucking nightmares. High-clearance 4WD essential for the mining spur roads, plus recovery gear for the inevitable stuck situation. Fuel up in Ouro Preto and carry 40 liters extra — services are sparse between towns. Camp permits required in state parks, but plenty of dispersed sites exist on mining claims. You’ll trace the actual routes that built Brazil’s colonial wealth, with views across diamond country that haven’t changed in centuries.
