Humahuaca is a town in the province of Jujuy, Argentina, adjacent to the spectacular Quebrada de Humahuaca on the main road from Argentina into Bolivia. Humahuaca is located up in the mountains at 3,000 meters above sea level, and has a population of a little over 10,000. A dusty ranching center surrounded by acres of cactus and spectacularly colorful mountains, Humahuaca looks like it should be a set for a wild west movie. The town has a bunch of hostels and campgrounds and is a popular destination for backpackers.
