Quilcayhuanca to Cojup: The Best Cordillera Blanca Trek You’ve Never Heard Of

While the world flocks to the famous routes, this demanding three-day circuit remains uncrowded. It connects two massive, parallel glacial valleys via a high, scree-covered pass, offering a raw and intimate experience of the Andes that the more manicured trails simply cannot match.

But here is the catch: you won’t find signposts pointing the way, and there is no “easy” option. Let’s be brutally honest for a second: the traverse over Paso Churup (approx. 4,850m / 15,912ft) is not a walk in the park. It is steep, the trail often disappears into unstable scree, and if the weather turns, you need legitimate navigation skills.

The Huaraz Backdoor: Two Valleys, One Epic Pass

This trek is all about dramatic transitions. It begins softly and ends in a spectacular crescendo of rock and ice.

• Quilcayhuanca Valley: A vast, flat, and extraordinarily green valley flanked by sheer granite cliffs that recall Yosemite—but with glaciers on top.
• Cojup Valley: Narrower, wilder, and more alpine. The crowning glory is Laguna Perolcocha, a deep turquoise lake sitting directly beneath the ice of Nevado Palcaraju.

Why This Trek Tops the Santa Cruz (For Some)

We respect the classics, but for the adventurous soul, the Quilcayhuanca to Cojup traverse offers significant advantages in terms of solitude and raw scenery.

Local Tip: Due to the demanding nature of Paso Churup, some animals cannot cross. We strongly recommend using professional porters for this circuit. They are faster, safer on the scree, and more adaptable than donkeys.

❓ Quick Answers for the Explorer

How hard is Paso Churup?

Physically, it is a demanding climb. The last 200 meters are on loose, steep scree. If you don’t have experience on unstable terrain at 4,800m, an AGMP-certified guide makes this section significantly safer.

Can I do this solo?

Technically yes, but it is high risk. The trail in Quilcayhuanca is boggy and the path over the pass is often lost. If you twist an ankle in Cojup, it might be days before anyone else passes by.
