Expedition to San Francisco Volcano, Catamarca, Argentina

Overview

San Francisco Volcano, located in the province of Catamarca, Argentina, near the border with Chile, rises to approximately 6,018 meters above sea level as part of the Andes mountain range. This stratovolcano consists of successive layers of lava and pyroclastic deposits, a testament to its historical volcanic activity. Currently, it is dormant.

This summit is renowned for its beauty and accessibility, thanks to the proximity of National Route 60 toward the San Francisco International Pass to Chile, allowing convenient vehicle access.

Day 1: Fiambalá - Hotel Cortaderas

The group meets in Fiambalá, a town with long-distance bus connections, accommodations, and food services. In the morning, a contracted vehicle covers the 97-kilometer distance to Hotel Cortaderas, located at 3,300 meters altitude. Short hikes are taken to aid acclimatization.

Day 2: Hotel Cortaderas - Provincial Highway Camp

In the morning, the journey continues to the Provincial Highway shelter, which includes a spacious dining area and often hosts other expedition groups. Water is sourced from a nearby stream and transported by the shelter staff.

Day 3: Acclimatization Day 1

The Provincial Highway shelter is near National Highway, Customs, and Gendarmerie facilities. Curiously, a customs procedure is required before reaching the shelter. This infrastructure is at 4,000 meters.

During the day, the group visits high-altitude lagoons inhabited by flamingos and climbs nearby hills for acclimatization. Health checks are performed. The group also visits a well-maintained thermal spring nearby, a popular campsite.

Day 4: Acclimatization Day 2 - Beltrán Volcano

The group ascends Beltrán Volcano, located north of the facilities. Vehicle access depends on road conditions. The summit is notable for its large crater. This climb is ideal for those not attempting San Francisco, offering a significant achievement and panoramic views.

Day 5: Camp at the Pass (4,700 masl)

Along National Route 60, strategically located mountain shelters provide safety. Shelter No. 6, on the watershed divide and international border, is a common high camp for climbers. At 4,700 meters, it serves as a dining and meeting point before summit day. Water is carried from the previous camp.

Day 6: Summit and Return to Fiambalá

At around 4:00 am, the summit ascent begins. The approach starts with a vehicle transfer. A higher camp at 5,200 meters is passed—rarely used due to its location in a depression, which can complicate the descent.

From there, the route follows a large diagonal leading to the crater rim, visible from the base. The summit lies on the opposite side of the crater and is reached by crossing it. In snow or penitente areas, crampons, an ice axe, and gaiters are recommended. The summit is broad and rounded, offering views of Incahuasi Volcano to the south.

Descent by vehicle allows return to Fiambalá the same day. The summit is celebrated at the Fiambalá hot springs, a unique location with thermal pools. A barbecue is possible if arranged in advance.

Comments

The Route of the Six-thousanders and San Francisco Volcano are known for their natural beauty, history, and diverse attractions. The summit is significant, but the expedition’s real value lies in the overall experience.

This Argentine destination remains under-publicized and low-impact, making it a hidden gem for those seeking untouched nature.
