Vale da Lua, which translates to "Moon Valley," is a unique natural wonder located in the Chapada dos Veadeiros National Park in Brazil. The valley is known for its lunar-like landscape, with smooth rocks that have been shaped by the flowing waters of the São Miguel River for millions of years. The rocks have taken on various shapes and forms, resembling craters, valleys, and ridges, and the area is surrounded by lush vegetation and crystal-clear pools of water.

Visitors to Vale da Lua can hike along the river, explore the unique rock formations, and swim in the natural pools. The area is also popular for its stunning sunsets and stargazing opportunities, as there is minimal light pollution in the park.

The name "Vale da Lua" comes from the resemblance of the landscape to the moon's surface. It is said that the rocks are so smooth and polished that they resemble the surface of the moon, and the valley is often described as a mystical and otherworldly place. The area has been featured in many nature documentaries and is considered one of the top attractions in the region.
