The Hill of Seven Colors, or Cerro de los Siete Colores, is a stunning geological formation located in Purmamarca, Argentina. This hill is famous for its vibrant layers of colored rock, which range from red to green, yellow, and purple. The colors are a result of different minerals in the sedimentary rock, shaped by erosion over millions of years. Visitors often hike the surrounding trails to enjoy panoramic views of the hill and the picturesque village of Purmamarca. The site is a popular destination for tourists seeking to experience the natural beauty of the Quebrada de Humahuaca region, a UNESCO World Heritage site.
