Paso Cristo Redentor is the main land border between Mendoza and Santiago. In summer it's a casual drive. In winter it closes — sometimes for a few hours, sometimes for three days — and that uncertainty is the whole story.
When it's open and clear, the crossing takes 6 to 8 hours by bus, 5 to 6 hours by car. Stunning drive, real Andes scenery, and dramatically cheaper than flying. When it's closed, you wait. Drivers sleep in their cars at the customs complex. Buses turn around.
The honest rule: only plan the land crossing if your schedule has a flex day on either side. If you have a flight to catch, fly. Santiago↔Mendoza is a 55-minute flight and there are 6 to 8 daily options. The bus is romantic until your transfer to Las Leñas gets pushed back 24 hours.
When it is worth it: you're moving slowly through both countries, you have time, and you want to see the high Andes from the ground. Take the morning Andesmar or Cata bus from Mendoza. Sit on the right side going west. Bring water, snacks, and a book — the customs stop alone can take two hours.
