From the Guardia Vieja sector (Carabineros, km114) the road is subject to a schedule for the summer and winter seasons. Summer time generally begins from September 1 to March 31 (year 2011), from Monday to Sunday, 24 hours a day. For updated data consult the page of the Border Crossing Unit.It is possible to arrive by public transport with buses that make the route Santiago – Mendoza (normally you must pay the full cost of the ticket)The permit is managed at the visitor service center of the Aconcagua Provincial Park located in Mendoza (Secretary of Tourism building: Av. San Martín 1143 – 1st Floor). The procedure is personal and is carried out by presenting the original DNI or identity card (Argentines) and original passport (foreigners). The permit is non-transferable and the fee is not refundable under any circumstances. From the entrance of the park to the first camp, known as Confluencia (here the Horcones River meets the estuary that descends from the south face), it is a 3-4 hour walk along a path that later becomes a gently sloping trail. In Confluencia there are several camping sites and there is even a “nursing tent” and another for “fast food” where hamburgers and drinks are sold. The second day of approach is a long journey from 6 to 8 am to the base camp “Plaza de Mulas”. The first part of this walk continues along the main path until entering the wide bed of the Horcones River that forms the Horcones Ravine. During a longPLaza de Mulas is a wide plain at the foot of a beautiful white hill called El Cuerno (5462m). During the summer the landscape is filled with multicolored tents that contrast with the Cerro Aconcagua predominance of ocher tones of the adjoining hills See photo 2. It is a good place to acclimatize since, in addition to eating and hydrating well, you can enjoy great international company . A few hundred meters from this place is the Plaza de Mulas refuge and here, in addition to being able to sleep and eat, you can play ping-pong and taca-taca. Once acclimatized it will be necessary to move towards the high camps. For this there are several alternatives of intermediate camps, but many of them have the shortcoming of not having water (or snow). It is therefore recommended to advance to the high camp Nido de Aconcagua AscentsCóndores (5400m) See photo 3, since it is a large place and has snow, although unfortunately it is not very sheltered from the wind and, due to the innumerable expeditions that have been Aconcagua Argentinahere, it is not very clean. Between base camp and Nido de Cóndores it’s 4h-6h for a long and loose haul. From this last camp several sectors of the route to the summit can be seen intersected by the northeast ridge because the route passes behind a sector of rocks deviating to the east and then returning to the center of the north face and crossing the high of the Gran Acarreo See photo 1. Above Nido de Cóndores there is another established camp (Berlin camp, 5700m) where there is also a wooden shelter Aconcagua The attack to the summit can be made from any of the high camps and the route is a well-marked trail of little difficulty, except for a couple of crossings over very hard snowfields. Lastly, once the Gran Acarreo is crossed, the trail ascends through a sector called La Canaleta See photo 1 where the slope is somewhat steep and the size of the rocks makes it necessary to climb sometimes with the help of the hands (crawling steps) . From the pass between the western and eastern summits, it is only a few minutes to reach the summit. See photo 5. The summit journey lasts approximately 8-12 hours depending on the capacity and level of acclimatization of the climbers. It is recommended not to be at the summit after 2:00 PM since the descent is not short (4h-5h) and in this way it is possible to reach the high camp with light.journey, almost completely flat, where you frequently have to jump streams and even the river itself, which, although it is not as mighty in some parts, does have quite a current. The last hours are along a path that winds along the slopes of the west face of Aconcagua until reaching the esplanade of the base camp (4250m).
