On my second trip to northern Argentina, I focused on visiting the Quegrada de Humahuaca, and getting to know the Serranía de Hornocal, which is a mountain range located 25 kilometers from the city of Humahuaca in the Argentine province of Jujuy. They are part of a colorful calcareous formation called Yacoraite, which extends from Peru. It is located at 4761 meters above sea level. it is reached through vehicle s x gravel roads! a place worth knowing !!
