Iztaccíhuatl, a majestic 5,230 m volcano in central Mexico, is both a symbol of mountaineering and a dream for hikers. Known as the “Sleeping Woman” for its silhouette, this giant of rock and ice attracts adventurers from around the world.

There are also guided hiking routes at lower levels (3,600–4,500 m) where you can safely enjoy spectacular views of Popocatépetl and the national park.
In this guide we’ll explain the difficulty of the summit—fitness, acclimatization, equipment, and altitude risks—while also showing you the easier Iztaccíhuatl hikes available for beginners and intermediates. 👉 Learn more about our guided Iztaccíhuatl hikes.

The Altitude Challenge
Altitude is sometimes a matter of luck and is one of the biggest obstacles when climbing to the summit of Iztaccíhuatl. Even if you have great physical condition, there’s no way to predict how your body will react; the only way to know is to go to the mountain.
As you ascend, the atmospheric pressure decreases, and the available oxygen reduces, and if your body is not sufficiently acclimatized and adapted to this altitude, you can experience Acute Mountain Sickness.
Common Symptoms of Mountain Sickness:
- Extreme fatigue
- Headache
- Nausea and vomiting
- Dizziness and vertigo
It’s essential to listen to your body and stop the ascent if you experience symptoms. Forcing the climb can have serious consequences.
If you want to enjoy Iztaccíhuatl without the risks of high altitude, there are guided hikes at lower levels (3,600–4,500 m). Our guided Iztaccíhuatl tours let you explore safely while still experiencing breathtaking views.
Recommendations
- Spend at least 3 days in Mexico City or Puebla. This will help your body begin to acclimate to the higher altitude.
- Camp at altitudes of 3,000 – 4,000m. This further aids in altitude acclimatization.
- Consult with your doctor if you can take any medication to counteract altitude sickness. Discuss potential options and any personal health considerations.
- If it is your first time on Iztaccíhuatl, or you do not have high altitude mountaineering experience, we recommend starting with level 1, level 2, or level 3.
