Vale da Lua, Natural rocky formation in Alto Paraíso de Goiás, Brazil.
Vale da Lua is a natural rocky formation in the Rio São Miguel valley near Alto Paraíso de Goiás, consisting of smoothed grey volcanic stones. The flowing water has polished and rounded the rocks over an extended period, creating curved surfaces throughout the valley floor.
This geological site formed through the erosion of ancient volcanic rocks by the São Miguel River over millions of years. The water gradually carved out the smooth formations visible to visitors today.
The site draws nature lovers and photographers who come to document the geological features and water formations. Visitors experience how flowing water shapes stone over extended periods in this natural setting.
A 45-minute walking route guides you through the rock formations without requiring a guide or paying entrance fees. The trail is easy to follow and does not demand special equipment or prior experience.
The rocks contain high amounts of quartz that split sunlight into rainbow patterns when combined with the emerald waters of the river. This light display appears most clearly when the sun is low and shines directly on the wet stone surfaces.
