Essential Gear – What to Pack for the Cordillera Huayuash
1. Backpack (50–70L)
Choose a comfortable, adjustable, and well-padded backpack with a sturdy hip belt. You’ll need space for warm layers, food, and gear if you’re trekking independently.
2. Daypack (15–25L)
If you’re with a guided group that uses donkeys for gear transport, bring a daypack for essentials like water, layers, snacks, and your camera.
3. Sleeping Bag (rated to at least -10°C/14°F)
Nights can get extremely cold—especially above 4,000 meters. A down sleeping bag with a compression sack is best for warmth and packability.
4. Sleeping Pad
A good-quality inflatable pad (like a Therm-a-Rest NeoAir or Sea to Summit) adds crucial insulation from the icy ground.
5. Tent (if not on a guided trek)
Choose a 4-season or alpine-rated tent to withstand high winds and potential snowfall.

Understanding the Weather on the Cordillera Huayhuash Trek
Weather in the Cordillera Huayhuash is one of the most important factors to consider when planning your trek—and it can be as unpredictable as the terrain is beautiful.
The trek reaches altitudes over 16,000 feet (4,877 meters), which means you’ll be exposed to extreme shifts in temperature and weather conditions, sometimes within a single afternoon.
The dry season runs from May through September, and this is by far the best time to trek. During these months, you’ll enjoy clearer skies, less rain, and better visibility of the towering snow-capped peaks.
That said, even in the dry season, you can expect cold nights (sometimes well below freezing), occasional afternoon storms, and strong winds—especially at higher passes.
Days often start off crisp and clear, then clouds may roll in by mid-afternoon, bringing wind or light hail.
Typical daily conditions during dry season (May–September):
- Morning: Clear skies, temperatures between 30°F to 45°F (around 0°C to 7°C)
- Midday: Sunshine warms things up to 55°F to 65°F (13°C to 18°C), but UV exposure is intense at altitude
- Afternoon: Cloud build-up possible, especially near passes; sudden wind or brief snow flurries can occur
- Evening/Night: Rapid drop in temperature—often below freezing, with lows down to 15°F (-9°C) or colder at high camps
The wet season spans from October to April, when heavy rains, snow, and cloud cover are common. Trekking is not recommended during this time unless you’re an experienced high-altitude backpacker prepared for wet, unstable trail conditions and limited views.
Landslides and impassable sections are more likely during this period.
No matter the season, UV radiation is intense due to the high elevation. You’ll need high-SPF sunscreen, sunglasses with UV protection, and a wide-brimmed hat or cap to protect your face.
Weather tips for the trail:
- Always layer—temperatures can swing from hot sun to freezing wind within hours
- Keep rain gear accessible in your daypack
- Dry bags or waterproof stuff sacks are essential for keeping your clothing and electronics safe from sudden weather changes
- Be prepared for icy conditions at night, even if the day is warm
Understanding Huayhuash weather helps you prepare not only your gear but also your mindset—embracing the unexpected is part of the adventure.
Final Tips Before You Go
Proper preparation will make a world of difference on the Cordillera Huayhuash trek.
Start training at least a few weeks in advance by incorporating cardio and weighted hikes into your routine to build endurance.
Once in Peru, spend at least two to three days acclimatizing in Huaraz to reduce the risk of altitude sickness—this step is essential given the elevation you’ll face on the trail.
Weather in the Andes is notoriously unpredictable, so pack as if you’ll encounter every season in a single day—sun, snow, wind, and rain.
Lastly, don’t bring anything untested. Make sure your boots are fully broken in and that you’ve tried all your key gear—especially your sleeping bag, filter, and stove—before you hit the trail.
