The Ausangate trek is one of the most intense and beautiful hiking experiences in the Peruvian Andes. Those wondering how difficult the Ausangate trek is should know that this route demands physical preparation, progressive acclimatization, and respect for altitude.
In this comprehensive guide, we explain everything you need to know about the challenge level of this adventure and how to enjoy it to the fullest—especially when done with professional operators like Huillca Expedition.
The difficulty of the Ausangate trek is generally classified as moderate to difficult, depending on the itinerary you choose, your physical condition, and your acclimatization level.
During the trek, hikers reach altitudes ranging from 4,000 to 5,200 meters above sea level, which can cause altitude sickness if not well-prepared. The journey also includes long days of hiking (5 to 8 hours per day), steep ascents and descents, and changing high-mountain weather conditions.

The difficulty of the Ausangate hike doesn’t depend only on altitude or distance—it results from a combination of physical, environmental, and logistical factors. Understanding them is essential to prepare properly and enjoy the trek safely.
The Ausangate circuit can be done in 3, 4, 5, or even 7-day itineraries, depending on the operator and group pace. Longer versions allow for more gradual acclimatization and rest, which helps reduce daily strain.
Shorter routes, though attractive to time-limited travelers, require greater physical endurance and fast altitude adaptation. These versions can be more demanding, especially for first-timers at high elevations. If it's your first time hiking above 4,000 meters, we recommend choosing a longer, slower-paced itinerary.
This is one of the most important factors. Most people who experience altitude sickness do so because they didn’t spend enough time acclimatizing. We recommend staying at least 2 to 3 days in Cusco (3,400 m) or similar-altitude areas like the Sacred Valley or Tinki before beginning the hike.
During those days, you can do gentle hikes such as Rainbow Mountain, Sacsayhuamán, or Humantay Lake. These help condition your body for the challenge of Ausangate, where some mountain passes exceed 5,000 meters.
You don’t need to be a professional mountaineer to do the Ausangate Trek, but a solid level of physical and mental fitness is essential. Hiking for 5 to 8 hours per day over rocky or steep terrain at high altitude, while carrying a 5–7 kg backpack, demands endurance, balance, and determination.
Pre-trek training should include long walks and cardio workouts (like cycling, swimming, or stair climbing). If possible, train at altitude. Additionally, sleeping well, eating nutritious food, and staying hydrated in the days leading up to the trek greatly improve performance.
The weather on the Ausangate route is as stunning as it is unpredictable. In a single day, you might experience intense sun, freezing wind, sudden rain, or even light snow, especially on the higher passes.
Nights are cold, with temperatures dropping below -5°C (23°F), particularly from May to August. You'll need appropriate gear for extreme weather, including a warm sleeping bag (-10°C rating) and the mental resilience to face challenging conditions.
Additionally, walking at altitudes above 4,500 meters means oxygen levels are 30–40% lower than at sea level. Even flat sections feel much more demanding.
If you're considering this incredible adventure, here are some practical recommendations:
Do long walks (at least 2 hours) 3 times per week for several weeks. Add cardio workouts like running, cycling, or stair climbing to build stamina.
Bring with you:
Although it's possible to do the trek independently, the safest and most rewarding experience is with certified local guides. At Huillca Expedition, we offer group departures, full logistics, pack animals, meals, and basic medical support.
It’s not recommended for complete beginners. However, if you're in good shape, have an adventurous spirit, and prepare properly, you can enjoy one of the most epic hikes in Peru.
The Ausangate Trek not only challenges your legs—it rewards every step with jaw-dropping scenery: rainbow-colored mountains, glaciers, turquoise lakes, herds of alpacas, and Andean communities preserving ancient traditions.
| Itinerary | Duration | Max Altitude | Difficulty Level | Recommended Acclimatization | Best for... |
| Short Trek | 3 days | 5,200 m | High | High (3+ days acclimatization) | Experienced athletes, time-limited travelers |
| Classic Trek | 5 days | 5,200 m | Moderate–High | Medium–High (2 days) | Fit adventurers with moderate time |
| Extended Trek | 6–7 days | 5,200 m | Moderate | Medium (1–2 days) | Relaxed pace, ample time to enjoy nature |
Longer itineraries allow better acclimatization and more time to enjoy the scenery. ❗ Shorter routes pack more physical effort into fewer days and require solid conditioning.
Though not a technical climb, the Ausangate Trek can be very demanding if you don’t respect the altitude or prepare properly. Here are the most common mistakes:
Many travelers arrive in Cusco and want to start hiking the next day. Big mistake. The body needs time to adjust to the altitude, or you risk nausea, headaches, extreme fatigue—or worse.
Tip: Spend at least 2 nights in Cusco and do a gentle hike before starting the trek.
Hiking above 4,500 meters with a pack for several hours a day is very different from city walking. Don’t assume anyone can do it without preparation.
Tip: Train 2–3 times per week for at least 3 weeks before, using stairs or local hikes.
Some travelers skip thermal layers or waterproof gear—and end up soaked, sunburnt, or freezing. Andean weather is unpredictable, and nighttime cold can be intense even in the dry season.
Tip: Wear layers, pack gloves and sun protection, and bring a proper sleeping bag.
Some travelers try to hike without knowing the terrain or having backup support. This can be dangerous in emergencies or with changing weather.
Tip: Hike with a reputable local agency like Huillca Expedition, which offers certified guides, meals, pack animals, and first aid.
