Trekker by a turquoise lake on the Huayhuash circuit with Diablo Mudo climb

Cordillera Huayhuash Circuit with Optional Climb (Diablo Mudo) — 15 Days

Repeatedly named one of the classic trekking circuits of the world, the Cordillera Huayhuash is a compact, rugged range of jagged, vertical summits among them Yerupajá Grande (6634m), the second highest peak in Peru, and half a dozen others above 6000m.

Every day brings towering snow peaks, hanging glaciers and turquoise, trout-filled lakes.

This 15-day circuit visits Siula Grande Base Camp (“Touching the Void”) and offers an optional, non-technical ascent of Diablo Mudo (5229m) for those who would like to add a summit to the classic trek.

The classic circuit, with a 5229m summit option

  • Trek grade: Hard
  • Climb: Diablo Mudo 5229m (optional, non-technical)
  • Duration: 15 days
  • Trek high point: Cuyoc 5000m
  • Highlight: Siula Grande Base Camp

The climb of Diablo Mudo is optional, non-climbers continue over the Yaucha pass to the same camp. No climbing experience is needed; we provide full instruction and support. Even so, you climb roped, with ice axe and crampons at altitude after a long moraine approach, so it should be considered both physically and mentally demanding.

When I started inquiring about trips many companies either didn’t respond or took a week or more, but right from the first prompt email Peruvian Andes Adventures was professional and thorough.

Essential Trekking Notes & Rules

The Optional Climb — Diablo Mudo

Diablo Mudo (5229m) is optional and beginner-suitable, with very little technical climbing in a normal year; we provide full instruction and support. It is still true mountaineering roped, with ice axe and crampons, after a long moraine approach and should be considered physically and mentally challenging. Non-climbers take the Yaucha pass to the same camp.

Calinca Valley Access

Access to the Calinca Valley and Siula Grande Base Camp is controlled by the Huayllapa community and not guaranteed; if refused, we camp at Huanacpatay and day-hike to the Cerro San Antonio pass for views of Siula Grande and its Base Camp.

Grading

Graded Hard for the length, the high passes and two weeks continuously above 4000m. Good fitness and comfort with sustained climbs, long descents and loose ground are needed.

Community-Owned Land

The entire Huayhuash circuit crosses privately owned community farmland, not a national park. Communities allow groups to pass and camp and charge access and camping fees (included in the trek fee), providing toilets at campsites. Please leave no rubbish and respect the local people and their animals.

Hiking Hours & Kms

Hiking hours are estimates including breaks and the lunch stop, for our average groups; the altitude affects people differently, so some are faster and others much slower. Distances are estimated. Access roads are unpaved and bumpy, so road travel is slower than the distance suggests.

Mountain Fine Dining

Five meals a day, at 4,000 metres

Good food is how your body keeps going at altitude. Every year, before the season starts, our cooks spend a course learning new trekking dishes, and on the trail they cook from fresh vegetables, fruit, chicken and meat. All drinking water is boiled. Menus change with each cook's favourite dishes; this is a typical day.
Vegetarian
Vegan
Gluten-free
Lactose-free

Breakfast

Porridge, quinoa or cereal, with eggs, pancakes or toast and marmalade.

Trail snack box

Nuts and dried fruit, biscuits, chocolate or sweets, a piece of fruit and a small fruit juice.

Cooked lunch

Protein, carbohydrate and vegetables — say a tuna and tomato salad with carrot, cauliflower, broccoli and rice — with herbal tea.

Afternoon tea

Popcorn, crackers, cheese, spreads and nuts, with extra treats like wontons and guacamole.

Dinner

A fresh soup (never from a packet), a main of chicken, fish, meat or a vegetarian dish with pasta, rice or potatoes and vegetables, and dessert.

What our Huayhuash trekkers say

"We were very particular about the itinerary and they work with us to make our specific desires happen… Our cook made the most amazing Peruvian food, and it may be the only trek where I gained weight."

Brian (USA) — Cordillera Huayhuash Trek, May 2018

"Our guide David is very knowledgeable in the history, flora, fauna and peaks. It’s amazing how he remembered the exact elevations of all the peaks we saw!"

Carolyn (Canada) — Cordillera Huayhuash Trek, June 2018

"Giovanni always making sure that I had protein at every meal! … I have been vegan for 16 years… I can’t believe that over 10 days I didn’t touch my emergency supply!"

Tamsin (UK) — Cordillera Huayhuash Trek, September 2017

What to pack for the cold

On a clear night in the Huayhuash the air can drop to between −5 and −12°C, and the sheltered campsites are the coldest. The ground is colder still, so bring a good four-season sleeping bag rated to at least −20 to −25°C, and a down jacket for the evenings.

  • Your trek bag travels by donkey: a soft duffel or backpack, never a hard suitcase, up to 15kg.
  • Line it with a waterproof bag so your sleeping bag stays dry if it rains.
  • We provide the tent, a foam mat and an inflatable Thermarest. If you have a good Thermarest of your own, it is worth bringing.
  • No sleeping bag? We can arrange one for hire in Huaraz.

Full trekking gear list

Getting there & when to go

From Lima there is one LATAM flight a day, leaving at 7am and landing in Huaraz at 8.10am, or an eight-hour tourist-class bus with Cruz del Sur or Movil Tours, by day or overnight.

The best months are May to September. June and July are the busiest. May and September are quieter, and May is green and full of wild flowers after the rains. Weather in the Andes is changing, so come ready for cloud and rain in any month.

Frequently Asked Questions: Cordillera Huayhuash Circuit with Optional Climb (Diablo Mudo) — 15 Days

Essential answers about this high-altitude route.

No. Diablo Mudo (5229m) is non-technical in a normal year and we provide full instruction and support. It is optional and beginner-suitable, but you still climb roped with ice axe and crampons at altitude, so good fitness is needed.

The climb is entirely optional. Non-climbers cross the Punta Yaucha pass with the crew to reach the same camp at Laguna Jahuacocha.

That depends on Calinca Valley access, decided by the local community when groups arrive. If refused, we day-hike to the Cerro San Antonio pass for views of Siula Grande and its Base Camp.
