Expedition Ski Mountaineering


Cerro San Lorenzo is one of the highest (3705m) and remote places of Patagonia, located approximately 300 km north of the Cerro Torre and Fitz Roy Massifs in and El Chalten. This impressive mountain is not as famous as other Patagonian areas and this is what gives it the flavor of a great adventure. This mountain chain of central Patagonia dominates one of the last explored areas in the world. Without a doubt, this offers to mountain lovers a wide range of opportunities.

Towards the west we have a dense rain forest, towards east the drier Patagonian steppe. Cerro San Lorenzo is the natural frontier that distinguishes the climates. There is an abundance of fossilized forests and paleolithic pits of the indigenous people that give testimony of the past in the forms of crafts and cave paintings.

Cerro San Lorenzo is an immense glaciated peak (the 2nd highest in Patagonia) located on the Argentine border SE of Cochrane. Remote valleys at the base of the peak make it spectacular for almost every trekker. The ascent of the peak itself is a 7 to 10 day mountaineering expedition requiring solid glacier progression and some simple ice climbing skills. It is an excellent option for ski tourers. The mountain was first climbed in 1943 by a team lead by the Italian missionary and photographer Alberto de Agostini.


Day 1:
Your mountain guide will meet you in the Balmaceda airport in Coyhaique, Chile.  Depending on your arrival time we drive to Cochrane through the wild Patagonia or stay in Coyhaique.
Night in Hotel.

Day 2:
From Cochrane, approximately 4 hours driving 4WD by traditional Chilean farms and estancias to the end of the road. We’ll drive as far as conditions allow us, and horses will be waiting for us to help take our load as we trek the rest of the way to a gaucho’s ranch “Fundo San Lorenzo”. We will be welcomed by the Soto Family and a delicious typical Patagonian asado.
Night in tents.

Day 3:
A 3-4 hour trek takes us to our base camp, Camp Agostini, at 1000 meters next to a milky glacial lake surrounded by big moraines. Horses will assist with hauling our mountain gear. Here there is a great cabin which is good comfort during bad weather days.

Night in mountain hut or tent.

Day 4:
From Camp Agostini, your mountain guide will take you on a 5-6 hour climb towards Paso Comedor, at 1950 meters. This will be Camp I, winter camping.  Most likely, we’ll be able to start skiing up from the hut through the forest, and we’ll soon be above tree line and the glacial moraines into alpine terrain.  Paso Comedor, the “Dining Room Pass”, gets its name from a large boulder that looks like a giant’s table.
Night in tent.

Day 5:
From Camp I, your mountain guide will rope up the team to travel across glacier terrain. Skiing and skinning ups and downs take us to Brecha de la Cornisa, 2150 meters. Traverse to access Glacier Calluqueo, the humongous glacier that covers the entire west face of the mountain. We will set up Camp II on the glacier right below the Northern Shoulder of Cerro San Lorenzo.
Night in tent.

Day 6:
Summit attempt day. From the tents, your mountain guide will take the team out skiing across the huge Glacier Calluqueo roped up.  We’ll be able to ski tour about 1/3 of the climb, and then once the terrain gets steep, we’ll leave the skis behind. A section of moderate snow/ice climbing on 45-55 degree slope brings us to the ridge. 

The hike along the ridge of the North Shoulder to the summit of Cerro San Lorenzo is through a beautiful labyrinth of ice formations such as huge ice mushrooms, gargoyles, and angel wings. Along the way to the summit the fantastic views demonstrate how this mountain divides east and west the dry Argentinian Steppe and the lush Chilean rainforests.  At 3705m, this is the second highest peak in Patagonia and lays directly between the Northern and Southern Patagonian Ice Caps. From the summit, on a clear day, you can see all the way south to the massifs of Fitz Roy and Cerro Torre and north to Patagonia’s highest peak, Cerro San Valentine (4058m). We’ll descend the same route to Camp II. This will be a long day.
Night in tent.

Day 7:
Descend to Camp Agostini-Descent to Fundo San Lorenzo ranch and a celebratory dinner with the gaucho family.
Night in the mountain hut or tent.

Day 8
Eather days before summit attempt in Camp Agostini at the mountain hut.  Depending on how bad the weather is, your mountain guide can take you on some short hikes to the nearby lake or surrounding valleys or low elevation skiing.  Or, enjoy the fire in the hut with a good book, game of chess, and mug of hot tea.
Nights in mountain hut or tent.

Day 9:
Descent to Fundo San Lorenzo ranch and a celebratory dinner with the gaucho family.
Night in tent.

Day 10:
Scenic drive to Cochrane. Drive to Coyhaique, Chile and drop off in Balmaceda airport.
End of guiding services.
Night in Hotel.

*The above itinerary is a guideline and subject to change due to weather and conditions.

*If we are able to summit without waiting because the weather is excellent, your mountain guide will have ideas as how to enjoy extra days dedicated to poor weather by exploring other nearby peaks and lakes, sightseeing, taking a boat to Glacier San Rafael near Coyhaique, etc.

7-17 October-2018



The Andescross family comes back to Southamerica with us and also to Antarctica, Norway, Iceland and the Alps for more good times.

“Back in 2006 I decided I wanted to try backcountry skiing and soon after I ended up contacting Jorgito at Andescross, which was already a very respected guiding company in Argentina.”

The idea of climbing all the mountains and volcanos in patagonia in the winter time and skiing them on the way down sounded too good to be true. Our first trip with Andescross was to Frey Hut with a couple of my brothers. The skiing conditions were as bad as Patagonia can offer so we ended up 2 days stuck in the hut in the midle of a storm and one day skiing on pure ice… 

Marcos Q.Tigre, BA, Argentina

“About 10 years ago I contacted Jorge about doing a hut to hut ski trip in the mountains around Bariloche. I chose him because he was a fully certified International Mountain guide.”

This trip proved to be nothing short of fantastic. Jorge was professional, friendly, knowledgeable of the area we were traveling through and was a great travel partner. He took care of my travel arrangements in Bariloche, booked my room for me before and after the trip, and even picked me up at the airport. The next year, I returned for a volcano ski trip with Jorge. We were fortunate enough to ski from the summit of four volcanoes. In the last decade, I have traveled with him at least 8 times.  We have skied in Chile and Argentina numerous times, including a trip to the Patagonian Ice-fields.

Tomfriend more than client since 2005

“I have skied with Jorge and Andescross in the Andes and the Alps in Europe.   Simply put, the Andes Mountain range is Jorge’s backyard and he knows then well.”

In my view, I think it would be very difficult to find another South American based guide with comparable years of experience in the Andes, guiding credentials, and local knowledge.  Over the years, Jorge has gained significant knowledge of the Alps and many other mountain ranges in the world which he includes in his worldwide adventure trips.  He is able to quickly gauge conditions, make safe decisions, and find great untracked skiing.  

Peter Musziclient for first time in 2008

“Jorge se ha convertido con el tiempo en un amigo cercano más que en un guía.”

Hemos compartido muchas aventuras juntos en varias partes del mundo como los Alpes, Bariloche y Chalten, y siempre regresamos de cada viaje pensando en el próximo. Para que un viaje sea exitoso tiene que tener su cuota de riesgo y cautela, algo muy difícil de lograr pero que Jorge siempre ha sabido manejar. Seguramente les quemara la cabeza hablando de… Paciencia estimados clientes!!, nadie es perfecto.

Francisco J.San Isidro, BA, Argentina

“In just over a six year period, we have done five trips with Jorge and have committed to a sixth next year. We must like this guy! Jorge is THE guide for your Patagonia adventures…and beyond! ”

Our first trip with Jorge in 2010 was for backcountry skiing around Bariloche, Argentina. While we were temporarily weathered out of higher terrain due to high avalanche danger from tons of new snow, we never lacked for fun, challenging, and noteworthy alternatives. He shared with us his hometown stashes, something only a generous local guide could do. Jorge is a consummate mountain guide. He is completely client focused. He is a first rate professional. We trust his judgement, thrill in his ski adventures, and have been blessed to enjoy the beautiful outdoors around the world with him.

“40 years ago I flew down to Argentina in my summer for downhill training in the Andes.
I was then racing on the World Cup circuit and so having 4 weeks on snow in summer was really useful training.”

I fell in love with Bariloche and returned the next year again. Sadly this was the last time I made to South America and then, when skiing in Iceland, I bumped into a friend of our guide, John Falkiner. We shared a few beers waiting for our airplane to fly home and John explained that his friend, Jorge, was a guide down in Argentina and that helped in Bariloche.

Konrad Bartelski A British Legend in Ski Racing in 1981

“Jorge and team helped with all the fairly complex planning and logistics for a supported backpacking trip across the Andes”

From Bariloche to Puerto Frias for our group of 10 people, and guided us safely along the route.  He and his guides were exceptionally competent, knowledgeable and professional, and everyone had a great time.  I would highly recommend Andescross!

Cheryl from The Mountaineers Hiking Club, Seattle WA

“I am currently travelling the world on a sabbatical, looking for amazing experiences. During a stop across south america, I wanted to rock climb in the Frey national park, near Bariloche.”

I found the Andescross team on the internet, and they teamed me up for 3 days with a world class guide instructor. I am a novice rock climber, and my guide Luciano not only provided me with amazing climbing coaching tips, but allowed me to push myself to go beyond my comfort zone, in all safety. And once the climbing was over (once summits were achieved and I could not feel my forearms anymore), it was time for some of the best hospitality I have found on the road this last year. Great dinners, food, friends and laughter to fill our evening, until the call of the rock would get us out of our sleeping bag the next morning.

“Jorge has excellent personal skills and appreciation of my climbing abilities. ”

Brian climber from CanadaI had the pleasure of meeting Jorge in December 2008. My wife and I were in Bariloche, on holiday in Argentina. Jorge had been recommended to us by a climbing friend back home in Canada. I was able to contact him by phone and we worked out a rendez-vous at the Refugio Frey for a day’s climbing on the rock. His knowledge of the area and the realistic time needed to complete various options, made it easy for me to reach a decision. What followed was one of the best days in the mountains that I have experienced over a lifetime in the sport.

Brian, 65, IrishCanadian climbing legend of Squamish, Canada

“Had a FANTASTIC time and thank you so much for all your help and the great guides. Great meeting you!!!!”

We are in BA, but head to Brazil tomorow and am just going to eat, drink and sleep! Anytime you head to Europe, you always have a place to stay in London and hopefully we will be back SOON!”
