Five Thousand Meters, One Day: Climbing Mateo for Your First High-Altitude Summit
A one-day, beginner-friendly 5,000-meter summit in the Cordillera Blanca—skills, scenery, and serious altitude with local guides.
You step from the van and the air feels different—thinner, colder, somehow more honest. Above the town of Huaraz the Cordillera Blanca stitches the sky with serrated teeth of snow and ice; the mountain called Mateo waits like a friendly tutor, its 5,000-meter shoulder attainable in a single, hard day. This is not the sort of summit that requires a lifetime of expedition experience. It is instead a calibrated challenge: a first serious step into high-altitude mountaineering where a sweaty, breathless morning becomes a clean, wide alpine view by afternoon.
Trail Wisdom
Acclimatize in Huaraz
Spend 2–3 days hiking local trails or doing a shorter peak before attempting Mateo to reduce altitude sickness risk.
Start before dawn
Summit pushes often begin very early—pack a headlamp and warm layers for the cold, still pre-dawn hours.
Practice with an ice axe
If you can, get a short lesson in self-arrest and front-pointing before the climb to build confidence on snow slopes.
Hydrate strategically
Sip frequently and use electrolyte tablets; altitude changes how your body handles fluids and salts.
Local Knowledge
Hidden Gems
- •Laguna Wilcacocha for a short acclimatization hike with views of the range
- •The town market in Huaraz for hearty local broths and fresh fruit juices

Conservation Note
Glaciers in the Cordillera Blanca are retreating rapidly; use local guiding services that support community conservation projects and practice Leave No Trace.
The Cordillera Blanca has been home to Andean cultures for millennia; many highland trails trace pre-Columbian trade and pilgrimage routes.
Seasonal Guide
spring
Best for: Fewer crowds, Cooler temperatures
Challenges: Late-season snow patches, Variable weather
Spring (local shoulder season) can be quieter with mixed snow conditions—good for solitude but check recent route reports.
summer
Best for: Dry weather (May–September), Stable summit windows
Challenges: Higher demand for guides, Strong sun exposure
The dry season is the optimal window for Mateo: clearer skies and more predictable weather, but book guides in advance.
fall
Best for: Good light for photography, Less tourist traffic
Challenges: Increasing precipitation late season, Colder nights
Fall offers crisp air and dramatic light; expect colder nights and potential early snow at altitude.
winter
Best for: Snow-covered alpine scenery, Lower temperatures ideal for firm snow
Challenges: Shorter daylight hours, Colder conditions requiring more gear
High-season for snow stability but cold—winters are quieter and demand proper cold-weather equipment and experience.

Common Questions
Do I need previous mountaineering experience to climb Mateo?
No technical history is strictly required, but basic fitness, comfort with steep terrain, and willingness to learn rope and ice-axe techniques are necessary; guided climbs are structured for beginners.
What altitude will I reach on the climb?
The summit is around 5,000 meters (approximately 16,400 feet); this requires careful acclimatization to minimize altitude sickness.
How do I get to Huaraz?
Most travelers fly into Lima (Jorge Chávez Intl.) and either take a 7–8 hour bus (or private transfer) north to Huaraz, or a short regional flight to Anta followed by a land transfer.
Is specialized gear provided by the operator?
Many guided trips provide technical gear (ropes, harnesses, sometimes crampons) but bring your own boots and confirm gear details with the operator before booking.
What is the risk of altitude sickness?
There is a significant risk above 3,000 meters—proper acclimatization, slow ascent, hydration, and recognizing symptoms early are essential; guides will monitor the group.
Are permits required?
Mateo typically does not require a special national park permit beyond local access fees, but regulations can change—verify with your operator and local authorities.
What to Pack
Insulated mountaineering boots (support & crampon compatibility), crampons + ice axe (safety on snow), layered clothing system (temperature control), water and electrolyte tablets (prevent dehydration at altitude)
Did You Know
The Cordillera Blanca hosts the highest tropical glaciers in the world; Peru's highest peak, Huascarán (6,768 m), lies in the same range and is a constant presence on clear days.
Quick Travel Tips
Arrive in Huaraz 48–72 hours before your summit attempt to acclimatize, book a licensed guide in advance during dry season, carry cash for local fees and tips, and insure for high-altitude activities.
Local Flavor
After the climb, head back to Huaraz’s Mercado Central for caldo de gallina and fresh fruit juices; celebrate with a shared meal of lomo saltado or a local stew at a small, family-run comedor, and check out a local microbrewery for a cold beer and conversation with guides.
Logistics Snapshot
Closest major airport: Lima (Jorge Chávez Intl.); regional: Anta (seasonal). Driving from Lima to Huaraz: ~7–8 hours. Trailhead access: short road transfer from Huaraz or nearby villages. Cell service: intermittent above 4,000 m. Permits: typically none for Mateo but verify with your operator.
Sustainability Note
Glacier retreat is visible here—support local guides, carry out waste, avoid single-use plastics, and stay on established trails to minimize erosion and habitat disturbance.
