By RP Nº 33 the road continues in a display of diverse panoramas, with curves ascending to a height of 3,348 meters above sea level.

The road to Cachi is majestic, and whoever embarks on this adventure finds incredible landscapes such as the Cuesta del Obispo with its highest point at the Piedra del Molino viewpoint, at more than 3,800 meters above sea level, from where you can get a beautiful view of the entire zone. The mountains that surround the town are a unique and imposing attraction.

They are 60 km of continuous zigzagging, until reaching 3,348 meters above sea level. From the iron bridge (passing the leaks), the typical hurdling scenery begins to dominate with hills of various colors that contain reddish, yellow or purple stones that come together and intermingle with the typical Puna vegetation full of teasels. Through numerous curves and counter-curves, the winding cornice path ascends in the middle of a landscape of high pastures. There are also wild and domestic animals of all kinds. You can see hummingbirds and condors that often fly majestically over the area.

Name's origin
The Cuesta del Obispo is so called because in 1622, the highest ecclesiastical authority of the time, Monsignor Cortázar, was traveling from the City of Salta to Cachi and, given the slow progress they were making, he had to spend the night halfway up the climb.

In the early days, the road was called "Cuesta de la dormida del Obispo", but later the name was simplified.

Historically, the Calchaquí Valley was much more populated than the Lerma Valley. First, by the natives who occupied the fertile lands on the banks of the river of the same name. Then they were subdued by the Incas and later, conquered by the Spanish after a long resistance. This slope witnessed the uprooting of the Chicoanas who lived in the Calchaquí Valley and who were deported to where today's Chicoana is located, in the Lerma Valley. The old inhabitants of the Valley say that in colonial times and until the beginning of the 20th century it took no less than three days from the city to Molinos. They set off in a horse-drawn carriage to the foot of the slope, where they would spend the night and continue on the back of a mule (an animal adapted to mountainous areas, a donkey-mare crossbreed) or on horseback. The old "tropero" path can still be seen in parts today. Arriving at the "La Cochera" post, you changed again and continued by car. Despite all these discomforts, he transported everything. Some traditional families own heavy and fine furniture brought from Europe.

At present, the 20 km slope is wide, graveled and permanently preserved. Its paving is irregular because it presents a marked geological fault that is visibly recognizable in yellowish color. In the meantime, it passes through La Herradura, where uranium was first discovered in Salta in 1959.

Piedra del Molino
It is the highest point of the Quebrada, at 3,348 meters above sea level and 93 km from Salta. From here you can appreciate an extraordinary view of the Quebrada de Escoipe. In this place there is a small stone chapel and a grinding stone carved in granite weighing several tons, which gives the place its name. It is said that it was transported by car in 1927 and that, due to the weight, it broke in two. It was destined for a ranch in the valley and its owners never returned for it.
