There is so much to see and do in the Quebrada de Humahuaca... It is not a World Heritage Site by chance. This gorge in the province of Jujuy runs for 200 kilometers between two spectacular mountain ranges (the further north you go the higher the mountains are). Going through it is a gift in itself, but it is worth stopping in some places and towns to soak up that unique culture. The more days you stay in this area the better. Some places you can visit are:
Lagoons of Yala (Potrero de Yala Provincial Park). There are six small lakes (only some can be visited) located in the limits between the montane forest and the misty pastures (ecoregion of Yungas). They are ideal for observation of avifauna: some one hundred and forty species have been identified, among them the Andean condor, the southern flamingo, the brown swift (species are in danger), the mountain turkey and the Rufous-throated Dipper (species geographically circumscribed to the Jungle of the Yungas). So, this is your chance ornithologists of the world, come here!
Purmamarca. Small town in the foothills of the mountain range whose main attraction is a multi-colored mountain called Cerro de los Siete Colores (The Hill of Seven Colors). Actually, all the mountains in the area have different tonalities. It is enough to go up to some viewpoints of the town or, better yet, walk the loop "Paseo de los Colorados", a one-hour hike through the beauty of the mountains around Purmamarca.
Maimará. Another beautiful village sandwiched between mountains. You can climb the mountain, swim in the river, chat with the locals, observe/buy local crafts, eat traditional food...
Tilcara. Charming town in which the local and traditional mixes with the modern and international. The surroundings are wonderful, standing out above the rest El Pucará: the ruins of a fortress built by the tilcaras on top of a hill (beautiful views of the valley). Amid that arid landscape full of cactus, there are several neighborhoods of houses, animal corrals, a necropolis and a place for sacred ceremonies. It is also highly recommended to visit the Garganta del Diablo, a walk near the town that crosses amazing landscapes and ends in this impressive waterfall.
Humahuaca. Another magical town that gives name to the Quebrada. Narrow cobbled streets, worth around on foot, and with its low adobe houses. Let's sing the "Carnavalito": “Fiesta de la Quebrada Humahuaqueña para bailar…”
Iruya. Outside the Quebrada, this community is, literally, "hanging on the mountain" (24 km north of Humahuaca, and another 4 km east, up the mountain). Its elevated (2780 meters) and isolated location gives it a mystical air that captivates the traveler. Apart from walking along its steep streets and chatting with locals and travelers, one of the great attractions remains a short distance away, in the small town of San Isidro, only accessible on foot. It is a beautiful eight-kilometers hike, following a river that goes zigzagging through a canyon (bring your spare shoes, because you need to cross it several times). You can camp under the stars anywhere.
Yavi. Also outside the Quebrada, more than 3,500 meters above sea level, lies this small town, whose main distinction is not only its beauty and Andean authenticity but also its history. Come and discover the only place that was a Marquesado in Argentine territory and its great Chapel of San Francisco. A few km from the town of Yavi, on the hill "Los Siete Hermanos"(The Seven Siblings), there is the "Laguna Colorada", around which there are petroglyphs of human figures, llamas, spirals, etc.
