Tips & Advice: Visiting this region
1. Weather: in the "Valles Calchaquíes" and the Puna
Dry climate with very low relative humidity. It only rains in summer (Nov. to March). Wide temperature swing between day and night.
Rain can cut highways due to flash floods and mudslides.
Dry air and high altitude make for clear sunny skies the rest of the year. Use sunscreen.
Cold winters with frost and freezing temperatures.
2. Height: Mountain sickness
When you go above 6,500 feet (2.000 m), air pressure drops, reducing the content of oxygen. This may cause nasty symptoms such as fatigue, nausea, headache, dizziness, and confusion.
Learn how to mitigate the impact of Altitude Sickness
4. Safety Tips
The paved part to San Carlos is easy. However, north of it, the road to Cachi is gravel-surfaced, narrow, and winding. It has sharp curves. It crosses some dry river beds and has a rough surface.
The "dry" river beds that cut across the highway are dry most of the year but will turn into rushing rivers during flash floods in the rainy summer season.
