Crossing the Highest Point Between Choquequirao and Vilcabamba

Introduction

At 5:30 in the morning, when the sun just begins to illuminate the peaks, you start walking. It is cold. The air is thin. Every step requires more effort than it should. Five hours later, you reach a point where the world opens up. At 4,650 meters (15,255 ft) above sea level, San Juan Pass offers a view that takes away the breath you already lack from the altitude.

The Choquetacarpo Glacier shines in front of you. The snow-capped peaks of the Vilcabamba mountain range stretch in every direction. If you are lucky, an Andean condor flies over the canyon, taking advantage of the thermal currents rising from the abyss. You are standing at the highest point of the traverse between Choquequirao and Vilcabamba. The same pass that Inca chasquis crossed 500 years ago. The same path Manco Inca used when he retreated to his refuge in the jungle.

This is San Juan Pass. The hardest and most spectacular moment of your trek.

The Context: Why You Cross This Pass

San Juan Pass is the gateway between two worlds. To the south lies Choquequirao, the “Cradle of Gold,” at 3,050 meters in a temperate cloud forest climate. To the north lies the Vilcabamba Valley, which descends toward the tropical jungle where the last Incas hid.

Between the two rises the Vilcabamba mountain range, a wall of snow-capped mountains exceeding 5,000 meters at its highest peaks. San Juan Pass, at 4,650 meters, is one of the few points where this wall can be crossed on foot.

The Incas knew this pass. They used it to connect their cities and ceremonial centers. Chasquis (messengers) ran through here carrying news and quipus from one side of the range to the other. When Manco Inca organized the resistance, this pass was part of the communication network that held the Neo-Inca state together. Today, crossing San Juan Pass is the only way to connect Choquequirao with Vilcabamba by land. There is no road. There is no shortcut. It is the same path used 500 years ago.

The Day of the Crossing

This is the longest and most demanding day of any trek that includes San Juan Pass. This is how it unfolds:

• 4:30 – 5:00 AM: Wake Up The chef wakes you before dawn. It is cold. You don’t want to leave your sleeping bag, but you know today is the big day. A hot breakfast follows: oatmeal, pancakes, eggs, and coca tea. Eat more than you think you can; you will need the energy.
• 5:30 AM: Start of the Ascent You leave the camp at Pinchauniyoc (~2,850 m). The sky just starts to lighten. You walk with a headlamp for the first 30 minutes. The trail starts gently through the upper part of the Choquequirao complex but soon begins to climb in earnest.
• 6:00 – 8:00 AM: Cloud Forest For the first two hours, you traverse the cloud forest. Moss-covered trees, orchids, and bromeliads line the way. The trail climbs constantly, but the vegetation provides a beautiful distraction. The temperature is pleasant, and there is still enough oxygen. This is the “easy” section.
• 8:00 – 10:00 AM: Transition Zone The forest opens up. Trees become smaller and twisted. You begin to see pajonal (tussock grass). The change in vegetation indicates you are gaining altitude rapidly. The air feels thinner. Your breathing accelerates. Your legs begin to feel heavy. Every break is welcome. The guide sets a slow, steady pace. “Poco a poco,” he says. “No rush.”
• 10:00 – 11:30 AM: The Final Climb The last 500 meters of elevation are the hardest. The grass gives way to rock and gravel. The incline intensifies. The air has 40% less oxygen than at sea level. Every ten steps, you stop to breathe. It’s normal. Don’t feel bad; everyone does it. The cold increases, and the wind blows. There may be snow or hail even in the dry season. You put on every layer you have. You see the pass above; it looks close, but every meter takes longer than it should.
• 11:30 AM – 12:00 PM: The Pass Finally, you arrive. At 4,650 meters, the world opens up. The effort of the last five hours is justified in an instant. In front of you, the Choquetacarpo Glacier shines under the sun. To your left and right, snow-capped peaks over 5,000 meters form an amphitheater of rock and ice. Below, the valley toward Yanama descends between mountains that seem infinite. The wind is strong and the cold intense, but you don’t care. You are standing at the highest point of your life (probably). You have crossed the Vilcabamba range following the same path as the Incas.
• 12:00 – 12:30 PM: Rest and Lunch The kitchen team, who left earlier, has a hot lunch or a substantial snack prepared. You eat while looking at the glacier. It is possibly the lunch with the best view of your life. Don’t stay too long; the cold penetrates quickly once you stop moving.
• 12:30 – 4:00 PM: The Descent Three and a half hours of descent toward Yanama. The descent is easier for the lungs but harder on the knees. The landscape changes in reverse: from rock to grass, from grass to shrubs, and finally to the first trees. The temperature gradually rises.
• 4:00 – 4:30 PM: Arrival at Yanama You arrive at the camp exhausted but satisfied. You have walked 9-10 hours. You have climbed and descended over 2,500 meters of combined elevation. You have crossed the Vilcabamba range. The chef has hot tea waiting for you. You take off your boots and look back at the pass you can no longer see. You did it. Early dinner. Early sleep. Tomorrow, the trek continues.

What You Will See at the Pass

• The Choquetacarpo Glacier: The dominant view from the pass. A glacier covering the summit of Mount Choquetacarpo (~5,500 m). It shines with white and blue tones under the sun. It is one of the most visually accessible glaciers in Peru, though it is retreating year by year due to climate change.
• Snow-capped Peaks: The Vilcabamba range has several peaks over 5,000 meters. From the pass, you can see a chain of snowy summits stretching toward the horizon. On clear days, some say you can see as far as Salkantay (6,271 m), though this is debated.
• The Canyon: Toward the Choquequirao side, the terrain drops dramatically into the Apurímac Canyon. You can see how the valley descends thousands of meters to the invisible river at the bottom.
• Condors: San Juan Pass is one of the best places to see Andean condors. Thermal currents rising from the deep valleys pass through here, and condors use them to gain height effortlessly. The best time is in the morning when the sun warms the valleys. Seeing a condor from above, as it glides below you, is an experience you won’t forget.
• Vicuñas: Occasionally, vicuñas are seen in the grass zones near the pass. They are the smallest and most elegant camelids of the Andes. Shy and fast, they usually flee before you can get close.
• The Silence: Perhaps the most striking aspect. At 4,650 meters, far from any road or village, the silence is absolute. Only the wind, your breathing, and the occasional cry of a bird of prey.

Specific Physical Preparation

San Juan Pass is the most demanding day of the trek. It requires specific preparation beyond general training.

• Acclimatization: You don’t reach the pass on the first day. Itineraries are designed so you arrive after 3-4 days of walking, with gradual height gain. However, the effects of altitude—heavy breathing, fatigue, a possible slight headache—will still be felt. It is normal.
• Ascent Training: The day of the pass includes 1,800 meters of elevation gain. You can prepare by:
  • Climbing stairs with a backpack: 45-60 continuous minutes, several times a week.
  • Finding local hills or mountains and making ascents of 1,000+ meters.
  • Incline intervals: 5 minutes of strong climbing, 2 minutes of recovery, repeat.
• Descent Training: After the pass, there are 950 meters of descent. Your knees will suffer if you haven’t prepared them:
  • Descending stairs with a backpack: 30-40 minutes.
  • Eccentric squats (lowering slowly, rising normally).
  • Strengthening quads and knee stabilizers.
• Endurance: The full day is 9-10 hours of walking. You need the capacity for prolonged effort:
  • 5-6 hour walks in your training.
  • At least a couple of consecutive days of long walking before the trek.

What to Carry That Day

Your daypack for the pass crossing should include:

• Layers of Warmth: It can be hot at the base and snowing at the pass. You need layers you can add and remove: technical base layer, mid-layer (fleece), a warm jacket (down or synthetic), and a waterproof jacket with a hood.
• Protection: Warm hat (for the pass), sun hat (for the ascent), gloves, Buff/neck gaiter, UV-protection sunglasses, and SPF 50+ sunscreen.
• Hydration and Energy: At least 2 liters of water and quick-energy snacks (chocolate, nuts, bars).
• Others: Trekking poles (essential for this day), camera with a charged battery, documents, and money.
• Target Weight: No more than 7-8 kg. Every extra gram is felt in the final 500 meters of the climb.

The Weather at the Pass

High mountain weather is unpredictable. Even in the dry season, conditions can change rapidly.

• Ideal Scenario: Bright sun, blue sky, moderate wind. Temperatures of 5-10°C at the pass. Perfect visibility of the glacier and peaks.
• Common Scenario: Partially cloudy. Clouds coming and going. Moments of sun and moments of cold. Strong wind at the pass.
• Difficult Scenario: Low clouds, mist, possible rain or hail. Reduced visibility. Intense cold. The crossing is still made, but the views are lost.
• Extreme Scenario: Thunderstorm, heavy snow, dangerous winds. In these cases, the guide may decide to wait or even postpone the crossing. Safety is always the priority.

Best Time: In the morning. That’s why we leave at 5:30 AM. Most storms in the Andes develop in the afternoon. Crossing before noon significantly reduces the risk of bad weather.

The Mental Challenge

San Juan Pass is not just a physical challenge; it is mental. Five hours of constant climbing, each step harder than the last, the lack of oxygen, heavy legs, and a pass that never seems to get closer. At some point, your mind will start to negotiate: “Why am I doing this?” “I should have chosen an easier trek.” “I can’t go on.”

This is normal. Strategies that help:

• Focus on the next step. Don’t look at the pass high above. Look at your feet. One step. Then another.
• Accept the slow pace. It’s not a race. Ten steps and stopping to breathe is perfectly valid.
• Remember why you are here. You came to experience something extraordinary. This is part of it.
• Trust that you will arrive. Thousands of people have crossed this pass. If you keep walking, you will get there.
• Celebrate small wins. Every 100 meters of height gained is an achievement.

The moment you reach the pass and see the glacier, all the suffering is forgotten. The reward erases the difficulty.

History: The Path of the Incas

You are walking through living history. This same pass was part of the Qhapaq Ñan (Inca road network). Chasquis, trained messengers from childhood, ran through here at speeds that seem impossible today. The chasqui system allowed a message to travel from Cusco to Quito (~2,000 km) in just 5-7 days. They ran in relays, from tambo to tambo, day and night.

When Manco Inca established his Neo-Inca state in Vilcabamba, this pass remained crucial. It was the connection between the various resistance sites. Messages about Spanish movements, attack plans, news of victories and defeats—everything passed through here. Walking through San Juan Pass is walking the same route used by the last defenders of the Inca Empire.

Condors: Kings of the Pass

If there is one animal associated with San Juan Pass, it is the Andean condor. With a wingspan of up to 3.3 meters, it is the largest flying bird in the world. But it is so heavy it cannot take off easily; it needs rising thermal currents to gain height.

San Juan Pass, where winds rise from deep valleys, is an ideal spot for them.

• How to see them: Best time is 9-11 AM. Look down toward the Apurímac Canyon. They usually glide in circles, gaining altitude. If you are lucky, they will pass at your level or even below you.
• What to look for: A distinctive silhouette with long, flat wings and “fingers” at the tips. A small, bald head and a white collar around the neck. Majestical flight with almost no flapping.

Frequently Asked Questions

• How difficult is it compared to other famous treks? The day of San Juan Pass is harder than the hardest day of the Classic Inca Trail. It is comparable to the Salkantay Pass. Prepare for the most demanding day of trekking of your life.
• Can the pass be avoided? It is the only route between Choquequirao and Vilcabamba.
• What if I can’t complete it? Guides constantly evaluate participants. If someone has serious problems (severe altitude sickness, injury), there are options like descending back to Choquequirao or being evacuated. However, most who reach this point can complete the pass.
• Is there shelter at the pass? Only natural rocks providing some wind protection.
• Can I do the crossing in the opposite direction (Vilcabamba → Choquequirao)? Yes, some expeditions do it this way. The effort is similar, and some prefer it because you arrive at Choquequirao as the climax.

The Moment You Won’t Forget

You are in the last meters before the pass. You are exhausted. Every breath is an effort. Every step a small victory. And then you arrive. The wind hits your face. The cold envelopes you. But you don’t care because the glacier is there, shining. The snowy peaks extend to infinity.

Something happens. You might cry. You might shout. Or you might just stay in silence, trying to process what you see and feel. No matter how many photos you’ve seen, when you arrive at San Juan Pass after five hours of climbing, the world looks different. You feel small in front of the mountains, but also capable of things you didn’t think possible. You made it. You overcame the range with your own feet.

Conclusion

San Juan Pass at 4,650 meters is the defining moment of the journey between Choquequirao and Vilcabamba. It is not easy—five hours of constant ascent at an altitude where oxygen is scarce. But the reward justifies everything: the Choquetacarpo Glacier, the snow-capped horizons, the condors gliding over the abyss, and the satisfaction of having crossed the Vilcabamba range following the same path as the Incas 500 years ago.

San Juan Pass is not for everyone. But if you are reading this, it is probably for you.
