Punta Unión Pass

The Santa Cruz Trek is one of the most established multi-day hikes in Peru’s Cordillera Blanca, a mountain range known for its concentration of high summits and glaciers. Typically completed over four days, the route covers around 50 kilometers (31 miles) of high-elevation trekking and links two broad valleys through a 4,750-meter (15,584-foot) crossing known as Punta Unión Pass.

For many trekkers, Punta Unión becomes the emotional and physical high point of the journey. It is the highest altitude reached on the route and the day that demands the most steady effort. By the time hikers arrive there, the trek has already built momentum. The body has adjusted to the rhythm of walking, the group has found its pace, and the landscape has gradually shifted from open valleys to more rugged terrain. Punta Unión marks the point where the steady buildup of the trek reaches its highest and most demanding stage.

What & Where: Understanding Punta Unión Pass

Located within Huascarán National Park, Punta Unión Pass connects the Santa Cruz Valley with the Huaripampa Valley. Most groups reach the pass on the second day of the trek, after camping in the Paria Valley.

Its role on the route is clear, Punta Unión serves as the central crossing linking two distinct sections of the Santa Cruz Trek. The first part of the hike gently gains elevation through wide valleys and pastoral scenery. After crossing the pass, the route transitions into a new valley system with different perspectives and terrain.

Its location along the route allows the effort to build gradually. The days leading up to Punta Unión give hikers time to acclimatize, settle into a steady rhythm, and gain confidence before taking on the highest climb.

Location & Altitudinal Facts

The Santa Cruz Trek generally begins near Vaquería at approximately 3,700 meters (12,140 feet) and finishes in the Huaripampa Valley at around 3,600 meters (11,800 feet). Punta Unión Pass, at 4,750 meters (15,584 feet), marks the highest elevation of the entire route.

Because of this altitude, it is also where the effects of thinner air become most noticeable. Even strong hikers may feel the slower breathing and increased effort required with each step. Preparation is key. Spending time in Huaraz before starting the trek, maintaining a steady pace, drinking water regularly, and listening to your body all play an important role in making the crossing comfortable and safe.

Reaching the pass depends more on maintaining a steady pace than on moving quickly. A measured rhythm, short pauses when needed, and a patient mindset make a significant difference at this elevation.

The Significance of the Pass

One of the reasons Punta Unión is so valued among hikers is that it offers a true high-altitude crossing without requiring mountaineering experience. The trail is demanding, but it remains a trekking route rather than a technical climb. With proper acclimatization and solid fitness, reaching the pass is entirely within reach.

This balance between challenge and accessibility is part of what makes the crossing memorable. The height adds intensity to the climb, but the path itself stays uncomplicated, making the crossing achievable with preparation and patience.

Long before trekking became a recreational activity, high mountain crossings like Punta Unión likely served practical purposes. Trails throughout the Cordillera Blanca connected communities, facilitated exchange, and allowed movement between valleys. This route likely formed part of that network.

The path underfoot has been used for generations, long before modern hikers arrived with backpacks and cameras.

The Ascent to Punta Unión: What to Expect

The climb to Punta Unión typically takes between three and five hours from the Paria campsite, depending on fitness, weather conditions, and the group’s pace.

Approach & Trail Conditions

From camp at roughly 3,900 meters (12,800 feet), the trail begins with a steady uphill walk through the open valley. The path is well-defined, and the early section allows hikers to settle into a comfortable rhythm.

As elevation increases, the landscape changes subtly. Vegetation becomes sparser, and the trail narrows in places. The final stretch toward the pass involves switchbacks over rocky ground. The ground is generally stable underfoot, but attention is required, particularly if there has been recent rain or light snowfall.

The higher you climb, the more deliberate your steps become. Conversation tends to quiet as everyone focuses on breathing and maintaining pace. There is a shared understanding in the group that this is the effort of the trek.

What the View Is Like at the Top

Reaching Punta Unión brings a wide view across the surrounding summits of the Cordillera Blanca, including Quitaraju, Artesonraju, and Rinrijirca. From this vantage point, it becomes easier to understand the magnitude of the terrain you have been walking through.

Below, glacial lakes punctuate the valleys, and the route you followed appears small against the expanse of rock and ice. It is common for hikers to pause longer than expected here. Not simply for photographs, but to absorb the feeling of having arrived at the highest point of the journey.

There is often a shift in energy at the top. Relief mixes with pride. The effort of the morning gives way to a sense of perspective. After a short rest, the descent begins toward the Huaripampa Valley. The most demanding climb is behind you, and the trek continues with renewed confidence.
