Before You Set Foot on Aconcagua: 20 Tips from the Team That’s Been There

Before you ever step onto Aconcagua, a lot of the outcome is already taking shape. These 20 practical tips come from decades on the mountain and focus on the things climbers can actually control before and during an expedition.

Before You Set Foot on Aconcagua: 20 Tips from the Team That’s Been There

Before you set foot on Aconcagua, a lot of the expedition is already taking shape. Not because the mountain can be predicted, but because many of the factors that influence the experience are still under your control.

Weather is not one of them. Much of everything else is. Your training, your gear, your pace, your attitude, your ability to rest, hydrate, eat, and communicate honestly with your guide all play a real role in how the expedition unfolds.

These 20 tips come from decades of experience on the mountain. They are not abstract advice. They are practical points that often make the difference between a solid expedition and a difficult one.

Before You Leave Home

  1. Make sure your passport will still be valid for your trip to Argentina, and verify any visa requirements for your nationality well in advance.
  2. Follow a consistent training plan before the expedition. If you are not hiring porters, you should be able to carry a 50 lb (22 kg) pack over 3,000 ft (900 m) of elevation gain in about five hours, several days in a row.
  3. If you are hiring porters, do not assume the expedition becomes easy. The load changes. The altitude does not.
  4. Bring every item on the gear list and make sure each piece has already been tested before arriving in Mendoza.
  5. Check that your crampons fit your boots properly before the trip. This is not something to discover at base camp.
  6. Prepare mentally as well as physically. Aconcagua is a long expedition, and the climbers who do best are usually the ones who focus on each stage rather than obsessing over the summit from day one.

Health and Acclimatization

  1. Get a full medical check before departure. Altitude tends to amplify whatever is already going on in the body.
  2. Understand how acclimatization works and learn to recognize the signs of altitude illness before you arrive on the mountain.
  3. If you take prescription medication, bring more than enough for the full trip. Running short at altitude is avoidable and unnecessary.
  4. Tell your guides about any relevant medical history or condition, even if it seems minor at sea level.
  5. Hydration starts early. Get used to drinking consistently before the expedition, not only once you are already on the mountain.

On the Mountain

  1. Move slowly, especially in the first days. Aconcagua tends to punish climbers who rush the early stages.
  2. Drink water regularly throughout the day, not only when you feel thirsty. Dehydration is one of the most common and preventable problems at altitude.
  3. Keep your gear organized and dry. A wet sleeping bag or poorly packed duffel can become a real problem above base camp.
  4. Eat even when your appetite drops. At altitude, fuel still matters, even when hunger does not show up the way it does at lower elevations.
  5. Protect your sleep. Rest is a major part of acclimatization, recovery, and decision-making.
  6. Be honest with your guide about how you feel. Not the polished version. The real one.
  7. Carry basic personal essentials where you can access them easily: sunscreen, lip balm, blister care, and whatever else you know you will need quickly.

The Human Side of the Expedition

  1. Look after your teammates and stay open to support from others. Expeditions tend to work better when the group functions as a team rather than as a collection of individuals.
  2. Respect your limits. Determination matters, but no summit is worth compromising safety. Knowing when to stop is part of climbing well.

These 20 points do not guarantee a summit. Nothing does. What they do is improve the quality of the experience and give you the best possible chance when the opportunity is there.
