At dawn the bus peels away from Salta, and the valley exhales. The road climbs; wind and light sharpen the landscape into high-desert reliefs, red gullies and salt-flat echoes. By midmorning the train waits at San Antonio de los Cobres, and the carriage begins its slow ascent toward La Polvorilla — rails that thread the Andean puna like a deliberate stitch.

The C-14 rail branch and La Polvorilla viaduct are outcomes of early 20th-century engineering to connect remote Andean communities; the viaduct remains an iconic feat of mountain rail construction.
Conservation
The puna is ecologically fragile — stick to marked areas, avoid disturbing wildlife, and support local craft vendors to help sustain community economies.

Acclimatize beforehand
Spend 24–48 hours in Salta or a lower-altitude town before the trip to reduce altitude sickness risk.
Carry at least 2 L of water
Dry puna air accelerates dehydration; drinking regularly keeps headaches and dizziness at bay.
Sun protection is mandatory
High UV at 4,000+ m requires SPF 50+, sunglasses, and a brimmed hat even on cloudy days.
Keep passport and voucher handy
You must exchange your voucher for a train ticket at the meeting point, and passports are checked for boarding.
Layered jacket (windproof)
Blocks cold winds on exposed high-altitude sections and provides temperature control.
High-SPF sunscreen & sunglasses
Protects against intense solar radiation above 3,500 m.
Reusable water bottle (2–3 L capacity)
Ensures adequate hydration throughout the long, dry day.
Camera with spare battery/memory
Slow-moving train and dramatic vistas reward photography; batteries drain faster in cold air.
