Two Giants, One Expedition If you’ve already climbed a 6,000-meter peak and are looking for your next big adventure, this expedition is built for you.
Why not tackle the world’s highest volcano and South America’s highest mountain — in one seamless trip? We’ll begin with a carefully planned ascent of Ojos del Salado (6,898m), giving you ideal acclimatization in a remote yet spectacular region. After reaching the summit, we travel to Mendoza and rest for a couple of days before heading straight to Aconcagua (6,962m) — the roof of the Americas.
Neither peak is technical. Aconcagua is a long walk on rough terrain, and Ojos del Salado involves a non-exposed scramble near the summit. But both demand respect: these are extreme altitudes where serious altitude illness can occur. That’s why our approach includes expert medical oversight, smart logistics, and acclimatization strategies that work. We use the “climb high, sleep low” method and remain flexible based on team health and weather conditions.
You just need to arrive well-trained, motivated, and with some high-altitude experience. We’ll handle the rest — with the support of Maximo Kausch, world record-holder for the most 6,000m+ summits in the Andes, and a team of seasoned high-altitude professionals.
Why Ojos First?
There’s a solid reason we’re starting this expedition with Ojos del Salado before heading to Aconcagua — and it goes far beyond route preference.
Due to extreme inflation in Argentina, the costs of climbing Aconcagua have surged by up to 150% in many services. In contrast, the Chilean side of the Andes — where Ojos del Salado lies — has remained far more stable and cost-effective. For that reason, we’ve shifted our acclimatization phase from Aconcagua to Ojos, giving you a more affordable and comfortable experience from the very start.
Over the last 3 years, Andes Specialists has built permanent logistics on the Chilean side of Ojos del Salado. We now have:
- Three of our own 4×4 trucks on standby full-time in the region - Permanent staff on-site year-round - A private basecamp with 2,000 liters of treated drinking water - Professional chefs preparing real meals — not freeze-dried rations - Dining domes, storage, private toilets, and generator/solar-powered electricity - Starlink internet for fast and stable connection - Access to an advanced mountain weather forecasting system
We’ve been refining our acclimatization strategy in this region since 2013, with over 21 expeditions to Ojos and deep operational knowledge of 19 other nearby peaks. This makes our approach not only more efficient but also safer and more flexible than any alternative in the Andes.
And there’s more: if you’re flying from Europe or North America, you no longer need to book a hard-to-find and expensive flight to Mendoza. You can simply land in Santiago, Chile — a major international hub — and we’ll pick you up and take you directly to the mountains. Mendoza isn’t even on the route anymore unless it’s for Aconcagua itself.
Why Climb with Us?
Decades of Experience: We’ve run more than 30 successful expeditions to Aconcagua and dozens to Ojos del Salado since 2012 — we know what works.
Unmatched Logistics: We operate our own logistics base in Mendoza and a full private basecamp in the Atacama with satellite internet, toilets, chefs, and reliable weather forecasting.
Real Talk, Real Experts: We only work with professionals who’ve summited these peaks. We’ll tell you honestly if this is the right expedition for your level and experience.
Proven Acclimatization Strategy: We follow “climb high, sleep low,” monitor oxygen saturation daily, and build margin days into the program. It works — and we stay as long as it takes.
Gourmet Chefs at Altitude: We hire professional chefs to prepare real food — not just freeze-dried meals — in the middle of the Atacama Desert and on Aconcagua.
Medical Expertise Comes First: Our guides are trained in high-altitude medicine and are supported by Maximo, who teaches it. We carry oxygen and a full medical kit and conduct daily health checks.
Top Guide-to-Client Ratio: We provide 1 guide for every 2 to 2.5 clients during summit attempts, ensuring you receive personalized attention and safety support.
Flexible Itineraries: More than 60% of our climbs adjust the schedule for weather and team needs — we stay on the mountain until you’ve had a real summit opportunity.

Mountain Guide
Andes Specialists is a guiding company founded in 2012 with a clear mission: to transform a passion for high-altitude mountaineering into a professional, adaptable, and reliable service. Created by Maximo Kausch, the company was born from his dream of turning a lifelong connection with the mountains into a project focused on deep knowledge, real guiding experience, and personalized service.
We operate exclusively in the Andes, not only in the most iconic mountains, but also in remote and rarely visited regions where few — if any — guides work. Our clients recognize us for our flexibility and ability to adapt to their goals, just like the mountains that inspire us.
All of our expeditions are led by certified guides, and we place special emphasis on a guide’s professional experience in the field — not just their personal climbing résumé. We believe that strong logistics, leadership, and group care are what truly define a world-class mountain guide.
Maximo Kausch, the founder, personally leads most of our expeditions. When he’s not available, clients are guided by handpicked members of his trusted team. Maximo has led over 10 expeditions to 8,000-meter peaks, several to 7,000-meter peaks, and more than 90 to 6,000-meter mountains. He has climbed over 250 extreme altitude peaks, reached the summit of K2, and currently holds the Guinness World Record for the most 6,000-meter peaks climbed — with 89 summits officially recognized.
At Andes Specialists, guiding isn’t just about reaching the summit — it’s about going beyond the obvious, with safety, expertise, and genuine connection.

The best food I've ever eaten, and it was in the remote desert. Incredibly skilled and helpful guides. Fantastic service and company, communication. Everything was 5 stars.
Renato
While we took coffee on the hood of the car, he took inside the hotel, he took more time than gave to us, leaving me and my wife waiting him to finish his meal

The expedition was very professionally organised with a good guide to client ratio (between 2:1 and 3:1), great food (cook Charlie was absolutely amazing, the food was better than in restaurants although we were in a remote location in a desert at 4,300+ meters above sea level), the guides all spoke English very well (big plus!) and the communication from the guides before and during the trip was very clear and helpful (e.g. asking questions what equipment to bring etc). Would recommend to others for sure
