Relief
The Cuesta del Obispo is one of Argentina's most spectacular mountain passes, located in the province of Salta. The road winds in countless serpentines from the fertile Lerma Valley up to the barren high-altitude desert of the Puna. Over a stretch of just 20 kilometers, it climbs an altitude difference of over 1,200 meters, reaching its highest point at Piedra del Molino at 3,348 meters. The name ('Bishop's Slope') dates back to a bishop who camped here during an arduous journey in the 17th century. Dense clouds often hang on the slopes, giving the moss-covered landscape a mysterious atmosphere. From the viewpoints, there is a wide-open panoramic view of the deep gorges and the bizarre formation of the Valle Encantado (Enchanted Valley), known for its unique high-mountain flora.
