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. It may be suitable for first-time mountaineers as long as they possess a penchant for cold weather and suffering.
Even though it is not difficult from a technical perspective (there is no extremely steep or glaciated terrain), Aconcagua’s ruggedness and fierce weather make it a real endurance challenge. Summiting Aconcagua via the 360 route involves long stretches of steep scree and – depending on the season – snowfield crossings, but no meaningful high angle climbing.
Daily mileage on the 360 Route varies widely, ranging from 2 to 15 miles, with anywhere between 2,000 and 4,000ft of ascent.
