Bolivia Trip Report | Adventure Ski Tours on 6,000-meter Peaks

From a Screenshot to a First Ascent? How a 3D Map Took Us to the Bolivian Andes

11/09/2026
Malte Hangler-Schulz
With a slope of about 55 to 60 degrees, over 6,000 meters high, and not a single report of an ascent, let alone a descent: We’re spending nearly four weeks in Bolivia on our snowboards and skis because of the southeast face of Ancohuma in the Cordillera Real. I discovered the face by chance on a 3D map. We want to find out on-site whether it’s actually skiable. A travelogue about splitboard tours and potential first descents on remote 6,000-meter peaks in the Cordillera Real (Ancohuma and Chearoco).

April 26, 2026, 11:30 a.m., 6,265 meters. I’m standing at the exit of the southeast face of Ancohuma, completely exhausted after a total of 9 hours of climbing from high camp. Below me lie 250 meters of elevation with slopes up to 60 degrees; serac breaks lurk at the very bottom. Falling is absolutely out of the question here. A few more big gulps of Inca Kola, a deep breath, then I carve my first turns into the face.

It all started with this face. While randomly flying around a 3D map of the Cordillera Real, its spines caught my eye. At the time, I didn’t yet know that these spines were about 70 degrees steep and the face between them ranged from 55 to 60 degrees. It was simply the aesthetics and the question of whether the wall could even be skied that made me dream about it.

There are no reports about the wall—not even of a single ascent. The 6,427-meter-high Ancohuma is usually climbed from Sorata via the Laguna Glaciar, meaning from the completely opposite side. I tried to get my friends excited with a screenshot of the face, and it worked for Matthias and Jonas. Jonas skis; Matthias and I ride splitboards. We don’t have any guides with us, nor any porters on Ancohuma. So, based on a screenshot, we’re flying halfway around the world to see if the face is really skiable!

Acclimatization and a Forced Break

At 3:30 a.m., we land at El Alto Airport at an altitude of over 4,000 meters. Even the 50-meter uphill walk to the hostel, carrying about 150 kilograms of luggage, leaves us completely out of breath. So we take it easy for the first few days, with a stroll through La Paz, a trip to the Valle de la Luna, and two days on Isla del Sol in Lake Titicaca. From there, the view stretches across the vast lake to the glaciers of the Cordillera Real; in the distance, Ancohuma and Illimani rise to over 6,400 meters.

Our first ski trip then takes us to the Condoriri region. From base camp at 4,700 meters—a very basic hut with a few mattresses, chairs, and a table—we set out on a leisurely ski tour to Pico Tarija (5,340 m). Since the snow is still very hard in the morning, we wait 1.5 hours at the summit in calm conditions until it softens around 11:30 a.m., and then ski all the way down to the very end of the glacier. The other peaks and slopes in the immediate vicinity (Ala Izquierda, Huallomen, and Condoriri) are too icy or too rugged this year, so on the third day we hike up to Pico Austria (5,350 m).

Back in La Paz, I come down with a gastrointestinal infection. The plan to climb Parinacota and the other volcanoes falls through; I just lie in bed, and nothing stays down. Even skinless chicken and a little rice are too much for my stomach. When a stable weather window opens up shortly afterward, I’m still feeling weak. We continue on to Peñas anyway, much closer to the Cordillera Real.

Peñas and the Trail to the Climbing Wall

The town is very small: one restaurant is open for lunch, another in the evening. There are also a few hostels and shops selling only the absolute essentials. Virtually no one knows anything about our planned route—not even the guides. Luckily, we meet Miriam, an Italian volunteer who lives in Peñas and helps boost tourism there a bit. She tells us that the drive to our starting point is almost never taken and goes through a community that isn’t very friendly toward tourists. Plus, without a 4x4, the route is completely impassable. Late in the evening, Miriam manages to arrange one of the few—perhaps even the only—4x4s in the area for us.

Because of the community, we set off with our driver, Sabino, at sunrise. Although the roads are marked on our 3D map, they’re barely recognizable in reality, so we help with navigation. Fortunately, we make it through the village without any problems; after that, there’s really only one possible “road” left. Around here, no one would even ride a mountain bike on it, but Sabino does a great job and takes us all the way to our planned starting point.

From here, we haul about 30 kilograms per person, first through swampy grassy terrain, then for several hours through pathless moraine scree. After setting up our first camp at 4,700 meters, we haul most of our gear up that same day and move the rest of our luggage to the high camp at 5,220 meters the next day. In the middle of the vast scree field, we find a beautiful, level, and rockfall-safe spot to pitch our tents. The scenery is breathtaking; we’re the only people for miles around. In the afternoon, we use a drone from our camp to scout a route through the labyrinth of crevasses that we plan to take that night.

The Southeast Face

The night is terrible. I haven’t fully recovered from the gastrointestinal infection yet, and on top of that, I’m suffering from severe cramps from the trekking food, so I barely sleep. The alarm goes off at 1:30 a.m. First on foot, then later with skins and crampons, we make our way slowly but steadily toward Ancohuma. The huge crevasses force us to take detours again and again, and in the pitch darkness, the right path is often impossible to make out.

As dawn breaks, the southeast face rises impressively before us. But the many hours in the dark without a break have taken their toll, so when the first rays of sun appear, we take a long break with Inca Kola and a Survival Bar.

After a few hairpin turns, the slope becomes too steep, and we switch to crampons. To our surprise, the snow on the face is still nice and powdery, heightening our anticipation for the descent. We briefly secure ourselves across the bergschrund, then continue ropeless. Breaking trail is very arduous; our footing isn’t secure, and the altitude and exertion don’t make it any easier.

An exhausting climb upward

Just above the bergschrund, we’re already measuring a 58-degree slope, and in the upper third, the wall steepens significantly once more. We briefly consider turning back. However, we can’t set a secure anchor—neither with ice screws nor snow anchors—where we could switch from crampons to snowboards and skis. So our only option is to push on upward, and we dig our way toward the exit at 6,265 meters. The snow gets deeper with every step. After three energy gels in an hour, I finally reach the top; Matthias follows close behind me. Jonas arrives at the exit a little later, also completely exhausted.

At 11:30 a.m., we decide to descend directly from the exit and skip the summit ridge, which would have meant nothing more than a long traverse. On the face, the slush becomes incredibly fast at a 60-degree incline, so we can only make diagonal turns and not directly down the fall line. We skip the 70-degree spines next to it. The snow conditions, however, are perfect and allow for a smooth descent. How often in life do you get to carve beautiful turns in powder snow at over 6,000 meters on a 60-degree slope?

No survival skiing, no slipping!

A rescue operation here would take several days. Only once we’re below the wall does the tension ease; the goal of the entire trip has been achieved, and I lie down for a moment. Matthias and Jonas also ski down with focus and make it down safely. On the steepness scale, we rate the descent as 5.5 E2. Since we found no prior ascent or descent reports, it’s highly likely this is a first descent.

We ski back toward camp across endless glacier fields and only now, between the huge crevasses, do we see where we’d been walking all night. For the rest of the day, we just lie around at camp; we’re so exhausted we can barely eat anything. The next day, we haul everything back to the starting point. We use a satellite phone to notify them of our planned descent, and Sabino is waiting for us right on time at the starting point. That evening in Peñas, we have a proper meal for the first time in many days.

Bonus: Parinacota (6,348 m) and Chearoco (6,127 m)

We still want to make up for Parinacota, which we had to skip because of my infection. Since Jonas is flying home on May 1, we’ll head from Peñas to Sajama—a six-hour trek without a rest day—to the volcanoes in the west, near the Chilean border. At night, a jeep takes us up to 5,100 meters; from there, we continue over volcanic ash and, after climbing 400 meters in elevation, on snow. My energy reserves are depleted, and although my backpack is significantly lighter than last time, every step is exhausting. Fuelled by plenty of sugar, I struggle my way to the summit—at 6,348 meters, the highest point of our trip. The view into the crater and of the surrounding volcanoes is breathtaking. After encountering some hard snow at the top and firn further down, we continue on foot over the finest volcanic ash once the snow ends.

We celebrate Jonas’s last evening in La Paz with a few cocktails overlooking the city rooftops and the Copa Libertadores match between Bolívar La Paz and Fluminense. The atmosphere in the fan section is incredible. In terms of soccer, the Brazilians are actually much better, but in the thin air at 3,600 meters, they’re knocked out right from the start. Bolívar wins 2–0, a well-deserved victory.

Three Donkeys and a Lonely Summit

For our final trip, Matthias and I are torn between the south face of Huayna Potosí and Chearoco. Huayna Potosí, with its mountain hut and easy access, would be the obvious choice, but the more than 100 summit attempters per day on the standard route put us off. In contrast, hardly anyone at the travel agencies in La Paz knows about Chearoco. Our savior is our trusty driver Daniel, who can drive us there and also knows the only donkey driver in the valley. This time, three donkeys carry our gear the more than ten kilometers to the high camp at around 5,070 meters, right next to a lagoon at the end of the glacier.

On the reconnaissance day, we use the drone to find a route through the labyrinth of crevasses on the southwest flank. On summit day, we alternate between crampons and ice spikes; in the upper section, we use skins, and we trudge the final 30 meters of elevation gain to the exposed summit. The weather is once again excellent and windless, so we enjoy our time at the top. The descent is great—powder at the top, firn further down—and we even ski the final stretch on the bare glacier (better to ski it poorly than to hike it well ;-)). According to Santos, the local arriero who owns the last house in the valley, we’re the first people to have skied or snowboarded on Chearoco.

Tips for Your Own Trip

The best time for ski touring is the transition from the end of the rainy season to the beginning of the dry season. This year (2026), we hit the sweet spot from mid-April through early May; depending on the season, it can also be a bit earlier or later. The closer it gets to “winter” or the dry season, the more stable the weather becomes. However, due to colder temperatures, increasing winds, and virtually no precipitation, the snow quality declines significantly. So, for powder and firn, it’s best not to arrive too late in the season—that way, the risk of slushy snow is also lower. In the volcanic regions, the dry season usually starts a bit earlier than in the Cordillera Real.

You should allow plenty of time to acclimatize, as the altitude right after El Alto and La Paz is already quite high. There are plenty of leisurely activities in and around La Paz and on Lake Titicaca to help with this.

It’s best to bring your ski and mountaineering gear from home. La Paz makes a good base; Christian from Andean Base Camp can help with transportation and drivers. For the Cordillera Real, the small but charming town of Peñas is better situated, saving you the 1.5-hour drive to El Alto—stau included. There are mostly simple hostels there; the Casona Don Ranulfo is a good base for climbers and mountaineers. For remote tours, be sure to pack a satellite phone. For those who prefer a more relaxed pace, destinations such as Pico Tarija, Mururata, Parinacota, Acotango, and Chachacomani are included in the itinerary for guided ski touring groups and are significantly less demanding.

The film about the trip: “Polvo y Pollo”

There’s also a film about the trip: “Polvo y Pollo” (Powder and Chicken). The film will be shown on November 7, 2026, at the Freeride Filmbase in the Metropolkino Innsbruck and on November 14, 2026, at the Salzburg Mountain Film Festival at DAS KINO.
And maybe you’ll get lucky—the film might also appear sooner or later on the Powderguide YouTube channel; it’s worth subscribing ;-)
