Fall runs down the mountainsides — cottonwoods glow in the river valleys while the peaks whiten. A short, lovely window before winter closes the high roads.
What to do in October
- Cottonwood gold along the Salmon River
- Last high-country drives before the closures
- Quiet-season soaks as the crowds thin
Best-fit rigs: Motorhome · Truck or van · Off-road rig
Know before you go
Many mountain campgrounds and services close during October; expect hard freezes.
Wildfires can close roads and campgrounds in late summer. Afternoon thunderstorms bring lightning risk in the mountains.
