The Gold Trail (Caminho do Ouro)

The Caminho do Ouro (Gold Trail) is a preserved section of the 18th-century stone road that connected the inland gold mines of Minas Gerais with the port of Paraty. The route features irregular 'pé de moleque' masonry (street child feet) laid by enslaved workers to prevent erosion on the steep coastal slopes. Today, hikers traverse a segment through the dense Atlantic Forest, where the historical stonework remains intact despite the aggressive root systems and high rainfall of the region. The trail provides a direct link between the deep jungle and the colonial architecture of Paraty.

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.
