Alto de Chorillos

Alto de Chorillos

Alto de Chorillos is a high mountain peak at an elevation of 4.806m (15,767ft) above the sea level, located in the Province of Salta, in the northwest of Argentina. It’s one of the highest roads of the country.

This infamous gravel road to the summit, located in the Puna de Atacama, desert is tightly hairpinned and bumped. It is subject to winter snowfalls with such a high summit altitude, and it can be closed anytime when the access is not cleared of snow. Make sure you get your vehicle and yourself well-prepared before driving this road.  4wd vehicle required. Stay away if you're scared of heights. Expect a trail pretty steep. After rain, even a single rainfall, conditions of the road can be challenging. Watch out for sudden loose-gravel breaks. Proper preparation is essential to having a safe, enjoyable trip on this road. At the summit sits an astronomical observatory known as the Large Latin American Millimeter Array (LLAMA). The weather on this zone is harsh and highly unpredictable. The climate is arid and cold: high temperatures vary little (since the warmer season is cloudy, and the coolest is sunny), ranging from 14°C to 21°C (57F to 70F), night temperatures go from 6°C (43F) in midsummer to -8°C (18F) in midwinter, and extremes under -15°C (5F) might be recorded. All rain falls exclusively in the summer, with values between 200 mm and 400 mm in total.
