Jujuy is the capital of the region of the same name in northwest Argentina, a geographical area known for the outstanding natural beauty of the UNESCO-listed canyon known as Quebrada de Humahuaca. Jujuy itself is home to some excellent sights: chief among these are the Museo Arqueologico (a stunning archaeological collection); Government House, which is home to Argentina’s original flag; and the fine 18th-century Iglesia Cathedral. Jujuy, most importantly, makes a fantastic base for exploring nearby Purmamarca, the start of the 155-kilometre canyon that draws visitors from all over the world. Purmamarca is located at the base of the astonishing natural sight of Cerro de Siete Colores, a hill consisting of seven different colours, stacked up in layers caused by millions of years of mineral deposits.
