Live the Mercedario Experience - Challenge the Eighth Highest Summit in the Americas

The Mercedario Hill (6,720 meters above sea level) is the eighth highest mountain in America and stands out for its isolation and wild beauty. Unlike the popular Aconcagua, here you will experience an expedition much more solitary, authentic and away from the crowds. It is the ideal destination for mountaineers looking for a real challenge and a deep connection with Andean nature.

Our 15-day expedition includes traverses through remote valleys, nights under a starry sky and the possibility of sharing the mountain alone with your group. The itinerary is carefully designed for a progressive and safe acclimatization, increasing your chances of success on the summit.

Route planning

Day 1: Meeting in Mendoza, welcome and preparation

We will meet in the city of Mendoza, the starting point of all the great Andean expeditions. We will have a briefing where the guide will go over every detail of the itinerary, answer questions and do a thorough check of the personal and collective equipment. This first meeting is essential to get to know each other as a group and make sure we are all ready for the adventure.

Day 2: Transfer to Barreal and trekking to Guanaquitos Camp (3,600 m).

In the morning, we leave by private transfer to Barreal, in the province of San Juan, enjoying the landscapes of the foothills and the San Juan desert. From Barreal, we take a mountain road only suitable for 4x4 vehicles to Laguna Blanca, where we start our trekking. There the mules are waiting for us to transport our heavy luggage. We walk for about 4 hours through imposing landscapes until we reach Guanaquitos camp, at 3,600 meters above sea level. First overnight in tents, surrounded by virgin nature.

Day 3: Acclimatization trek to Turquesa Stream (4,000 m)

Today we make a gentle 3 to 4 hour round trip hike to the beautiful Turquesa stream. This trek is fundamental to begin the acclimatization process, allowing our body to adapt progressively to the altitude. We return to Guanaquitos camp to rest and enjoy a well-deserved lunch and dinner.

Day 4: Ascent to Cuesta Blanca Camp (4,400 m)

After an energetic breakfast, we dismantle the camp and begin the ascent to Cuesta Blanca, at 4,400 meters. The hike takes about 5 hours and the loads are carried by mules, allowing us to carry only the essentials in our backpacks. We cross high mountain landscapes, with unique panoramic views of the mountain range. We settle in the new camp and rest in double tents.

Day 5: Rest and acclimatization day at Cuesta Blanca

We dedicate this day to rest, hydrate and continue acclimatizing in Cuesta Blanca. We take the opportunity to review mountain techniques, organize the equipment and contemplate the wild environment. This strategic rest significantly increases the chances of success on the summit.

Day 6: Equipment portage to Pirca de Indios (5,200 m) and return.

Today we carry equipment and food to the Pirca de Indios high altitude camp, located at 5,200 meters. This day is key for acclimatization and to leave part of the equipment ready at altitude. The activity takes between 6 and 7 hours in total. At the end, we return to Cuesta Blanca to rest.

Day 7: Ascent to Pirca de Indios Camp (5.200 m)

After breakfast, we break camp and ascend to Pirca de Indios, carrying the rest of our personal gear. The day offers increasingly impressive views and the challenge of advancing in altitude. We set up camp, share dinner and rest.

Day 8: Rest and acclimatization day at Pirca de Indios

Another key day for acclimatization, fundamental for success in the high mountains. We rested, hydrated, replenished our energy and enjoyed the tranquility of the environment, almost always in absolute solitude.

Day 9: Portage and acclimatization to La Hollada (5,700 m)

Today we do a portage and acclimatization to La Hollada camp, at 5,700 meters. The activity, which takes 6 to 8 hours, helps our body to adapt to the extreme altitude. We leave equipment and supplies at La Hollada and return to Pirca de Indios.

Day 10: Ascent and overnight stay at La Hollada (5,700 m)

Finally we ascend to La Hollada, where we will spend the night at high altitude. This camp is the base for the summit attempt and represents a great achievement in acclimatization and personal effort.

Day 11: Rest and acclimatization day at La Hollada

We take advantage of this day to rest, replenish our strength, hydrate and check all the necessary equipment for the summit attempt. Patience and proper acclimatization are key to success.

Day 12: Summit day at the Mercedario (6,720 m)

We start very early the most important challenge: the ascent to the summit of Mercedario. The round trip can take between 10 and 12 hours, depending on the conditions and the group. The last stretch is demanding, but the view from the summit, one of the highest and most spectacular in America, rewards all the effort. After the summit, we descend to La Hollada to rest.

Day 13: Descent to Camp Guanaquitos

We begin the gradual descent to lower altitudes, returning to the Guanaquitos camp. From Cuesta Blanca the mules are in charge of transporting the heavy equipment, allowing us to enjoy the descent and the change of scenery.

Day 14: Return to Laguna Blanca and transfer to Mendoza.

We walk to Laguna Blanca, where the private transfer awaits us to take us back to Mendoza. Here the expedition ends, closing an unforgettable high mountain experience.

Day 15: Extra day due to bad weather or acclimatization

An additional day that can be used in case of adverse weather conditions or to improve acclimatization, ensuring maximum safety and increasing the chances of success on the summit.
