One of the most wonderful trekking routes in the northwest region of Argentina
As hundreds of years ago, as the Incas did, we will try to unite these small villages of Colla origin, which are capriciously nestled in ravines and hills. The task is not easy, but the contrast between the blue sky and the rainbow the colors of the imposing mountains fill our senses, they invite us to continue, step by step, through those narrow paths, through those deep ravines, wading through those torrential rivers.
At sunset, in the heights, share some mates with some other old settler, listening carefully to his story, enjoying its warmth but without losing sight of those high peaks that watch over us, with that blanket of clouds that shelters them when the evening approaches.
What we present here is the planned route for the crossing, but the exact route, the duration of each stage of the march and the choice of alternative itineraries are subject to different factors such as weather conditions and group evaluation by the guide.
Day 1: This day you have to be in the town of Iruya to spend the night there, to have the meeting with the guides and be ready to start the next day. After noon. We advise you on how to travel to Iruya.
NOTE: Ask for the week prior to this date, that we will be doing the other great Calilegua-Tilcara trek; possibility of joining the two routes.
Day 2 Iruya-Chiyayoc: With the first rays of light, breakfast, armed with loads and, with backpacks on our shoulders, we went for a walk on our first day. Gentle and short descent to the Iruya river ravine. From here a steep climb awaits us to the pass of San Juan (from where the view is incomparable). After a light lunch, we went down to the ravine to face our last ascent: to Chiyayoc, a small town scattered on the side of a large hill, along a small valley, at 3000 meters above sea level. Intense day of 9 hours of walking. Night in beds.
Day 3 Chiyayoc-Rodeo Colorado: We have breakfast with the warmth of the first rays of the sun, we set off heading north. We start a slow and continuous ascent, until the "open" from where we descend by a "multicolor" path to another small town: Rodío. Lunch at La Loma. In the afternoon we continue to Rodeo Colorado at 2,950 meters above sea level. Overnight in cabins.
Day 4 Rodeo Colorado-Molinos: Free morning to explore the town. We can wake up with the school bells. A day of ups and downs, stalls with residents who greet us as we pass, rushing streams and huge stone walls. Our day culminates in another small town, Comunidad de Molinos. Capriciously founded on a ridge with a beautiful view of the Nazareno River valley. Long day of 8 hours of walking. Night with sleeping bag in room.
Day 5 Molinos-Nazareno: We wake up early, have a light breakfast, prepare the equipment and assemble the loads. The trail winds and descends into a huge valley, then begins many river crossings. In the afternoon, we arrive at the end of our journey, at the picturesque town of Nazareno (3000 masl). After settling in a simple shelter in the community, we went out to explore the town and look for a place to have a tasty meal of homemade food. Extensive day of more than 8 hours of walking. night in bed
Day 6 Nazareno-La Quiaca: Very early in the morning, our charter transport picks us up and takes us to La Quiaca. There are 100 kilometers of film, steps at 5000 meters high, winding roads, llamas and vicuñas everywhere... At approximately 9 am we arrive at La Quiaca. End of our journey. Here you can hire a bus service that takes you to Jujuy or Salta, which depart permanently.

This trekking is for people who are in good physical condition to withstand an average of 6 to 8 hours of mountain walking, for several days, at an easy but constant rithm, leaving from San Francisco, Calilegua, with a spectacular landscape transition. With a lot of vegetation change, and where we are in full contact with people living in the mountains and with Nature. In only 70km, from the nuboselva, from the Calilegua National Park to the semi-desert, in the Quebrado de Humahuaca.
Cliffy trails to large valleys.
For any mountain activity you need to have a previous physical preparation, or be physically active. In this case we suggest Aerobic training (going for a run two to three times a week, cycling or swimming) and doing a good leg workout (gym, crossfit, AEX training, etc.)
We recommend walking at least once before this trekking with a backpack, although no previous experience is required.
The idea of ??this trek is to be able to share the experience with local people, in family homes. Overnight takes place in those houses of local people, with basic services. They have mattress beds.
Although the time of the year is optimal for this crossing, in mountain and/ or wild areas temperatures tend to fall at night. There may be the possibility of rain storms, hence the importance of personal equipment. Non of what we detail in the equipment list can be missing.
Stops are given with a frequency and graduation according to the intensity. There are breaks for lunch, snack, and rest.
From 13 years old onwards. We also recommend you to contact us before registering or registering a minor just to make sure that his/her experience is the suitable for this trek.
On this tour, having pack animals, you can walk with a small backpack (between 35 and 45 liters) with the things we use during the day (coat, sunscreen, flashlight, water, etc.)
We have a mule carrying the general equipment, such as kitchen elements, food, tents, and security elements. They also carry some of your equipment, an approximate of up to 7 kilos per person.
It is necessary to complete the personal / medical file to clarify if someone does not eat some type of food.

Tilcara Calilegua es la travesía mas hermosa que hice, tiene unos paisajes maravillosos . La inmensidad en la montaña es increible. Pero lo que realmente lo hizo mágico fueron los lugares donde nos hospedamos, los compañeros de montaña y el amor y el cuidado de los guías. Euge y Gus estuvieron en cada detalle, pendiente de cada uno de nosotros, realemente ellos fueron el viaje. La comida increible. Agradecida eternamente con ambos..
Fui a Tres Picos con Mati y Fer de AEX. Todo sucedió como estaba organizado. Tanto los guías como Euge estuvieron disponibles desde el día 1 de la reserva para evacuar todas nuestras dudas y llegar de la mejor manera al trekking. Súper recomendable viajar con AEX.
