Aconcagua 360

December 1-22, 2023

About the Trip

Operated by AWE and local partner INKA Expediciones

Aconcagua is the highest peak in Argentina and the tallest mountain in the western and southern hemisphere, which means it is also one of the Seven Summits. Even though it is not difficult from a technical perspective as there is no extremely steep or glaciated terrain, Aconcagua’s ruggedness and fierce weather make it an endurance challenge of a special kind. This is an extremely demanding trip that may be suitable for first-time mountaineers as long as they possess a penchant for cold weather and suffering.

We’ll be climbing the mountain via the longer, more rugged, less crowded and much more beautiful 360 Route. To learn about AWE founder Sunny’s history on the 360 route, check out this National Geographic article.

About Aconcagua and the 360 Route

At 22,838ft Aconcagua is the second highest of the Seven Summits, and the highest mountain in the world outside of Asia. Aconcagua is located on the Chilean-Argentinian border, some 65 miles as the crow flies northwest of Mendoza. The 360 expedition starts at Aconcagua Provincial Park’s Punta de Vacas gate (8,100ft ASL) near Penitentes, which is about three hours by car from Mendoza. From here the journey continues on foot through the arid Vacas Valley, climbing gradually until a few miles before basecamp Plaza Argentina (13,800ft) where the terrain steepens acutely. We will arrive in basecamp after three days of walking and then take 11-12 days on the upper mountain to push higher and position ourselves for a summit bid before descending on the opposite side of the mountain, which allows us to make an almost complete loop around Aconcagua – hence the name ‘360 Route’

No prior mountaineering experience is required. Participants must be in excellent physical condition. Previous backpacking experience is required. Previous high altitude experience (14,000ft+) is highly recommended but not mandatory.

Trip duration: 21 days / 22 nights
Max group size: 8 guests & 2 guides

You will receive a detailed packing list in your expedition handbook after reserving your spot on this expedition.  AWExpedition and local partner INKA Expediciones provide the team, cooking and emergency gear for this adventure including sleeping tents and cooking equipment; you are responsible for your personal backpacking gear including the following items:

  • Double mountaineering boots
  • Ice axe, crampons & climbing helmet
  • Sleeping bag, rated to -20F or -40F
  • 65l+ backpack
  • Sleeping pads
  • Expedition weight down jacket
  • Hardshell (GoreTex) jacket
  • High-altitude mittens

A broad selection of rental gear is available through national brands such as REI or Kit Lender. It is also possible to rent many items, including mountaineering boots and expedition weight down jackets on location in Mendoza. 

Inclusions

  • Airport transfers
  • Hotel accommodation and main meals pre- and post-climb, as well as meals on the mountain (including water & coffee/tea)
  • Professional guide team including AWE expedition leader and local Argentinian guide(s)
  • Team gear including four-season tents (double occupancy), cooking equipment & team medical kit
  • On-trail real-time GPS tracking and communications
  • Mule support up to 20kg per person to support the approach to basecamp

Other costs 

  • Flights to/from Mendoza
  • Government climbing permit (~$950 for 20 days, payable in USD on arrival)
  • Personal mountaineering gear
  • Gratuities for guides
  • Meals not listed in the itinerary
  • Sodas & alcoholic beverages
  • Personal trekking snacks (such as bars, trail mix, or beef jerky) for on-trail sustenance
  • Personal medications
  • Medical, travel, and rescue insurance
  • Single supplement - contact us to discuss availability and pricing
  • Personal porter support above basecamp, if desired

  • How fit do I have to be? Aconcagua is an extremely demanding high-altitude mountaineering expedition. You have to be in outstanding cardio shape to tackle this 23,000ft mountain and enjoy the adventure.
  • How difficult is the route? While the technical difficulty of the 360 route is low, it is an extraordinarily (and frequently underestimated) difficult cardio challenge. Each day on Aconcagua is difficult in its own right; summit day may very well prove to be the hardest physical and mental challenge of your life.
  • How much weight will I have to carry? Your pack on the way to basecamp should be no heavier than 20lbs, thanks to mule support.  Above basecamp, you have to be prepared for 35-40lbs of weight during each leg of our ascent, and up to 65lbs of weight for the return to basecamp after our summit attempt. If you'd like to decrease the weight you have to carry above basecamp, it is possible albeit pricey to hire personal porters on the upper mountain.  20kgs / 44lbs of porter assistance from basecamp to camp 3 and back down to basecamp typically come out to $1,000.
  • How many miles will we hike each day? Daily mileage on the 360 Route varies widely, ranging from 2 to 15 miles, with anywhere between 2,000 and 4,000ft of ascent.
  • Should I be taking acetazolamide (Diamox) to climb Aconcagua? That's a question for you and your physician. Many climbers are able to summit Aconcagua without Diamox, but if you haven't been to 23,000ft before there is no telling how your body will react to extreme altitude: our bodies' ability to acclimatize is mostly determined by genetics, and the best predictor for your ability to acclimatize is prior performance at high altitude.  In addition, Diamox takes 24-48 hours to become effective. Here's what that means for those who don't have prior experience at extreme high altitude, i.e. no insights into their ability to naturally acclimatize: if you'd like to maximize your summit chances, Diamox may be advised (note: it does carry negative side effects; consult with your physician when you seek to obtain a prescription).  If you'd like to find out what your body is naturally capable of, pass on the Diamox.
