Cuesta del Obispo, or Bishop’s Slope, is a hill southwest of Salta, Argentina along the way to the village of Cachí. Its name derives from the 1600s when a bishop was traveling through the area. He was so mesmerized by the sky that he decided he had to stop and sleep under the stars that night. The locals started calling the hill the Slope Where the Bishop Slept, and eventually it was shortened to Bishop's Slope.
The hill is in the Calchaquí Valley, which was once much more populated, but the natives were conquered by the Incas who were later conquered by the Spaniards. The hill offers a perfect viewpoint over the Enchanted Valley. The slope itself is a long dirt road that leads up the hill and ends at La Piedra del Molino (the Millstone) at an elevation of nearly 11,000 feet above sea level.
