If the Cordillera Blanca has a single signature trek, it’s Santa Cruz — four days that pack in glacial lakes, a genuinely spectacular high pass, and a close-up view of Alpamayo, a peak so symmetrically beautiful it’s frequently named the most beautiful mountain in the world by climbers and photographers alike.
The trek’s structure makes it unusually efficient for what it delivers: a gradual, well-graded approach up the Santa Cruz valley builds toward Punta Unión pass at 4,750m on day three, where glaciated peaks appear on both sides of the trail simultaneously, before a long descent down the parallel Huaripampa valley completes the loop. Compared to the longer, more remote Huayhuash Circuit, Santa Cruz is accessible in a long weekend from Huaraz without sacrificing much of the range’s signature scenery.
The trail sits entirely within Huascarán National Park, a UNESCO World Heritage Site, and a modest park fee is the only formal requirement — no permit quota limits numbers here. May through September is the dry season and by far the best window; outside it, the high pass can become genuinely hazardous with fresh snow and poor visibility.
