A bed at the end of the pavement
The towns that matter are the ones where the dirt begins. Elk City sits at the end of State Highway 14 with fuel, rooms and food before the Magruder corridor. Stanley sits at the top of the Sawtooth Valley, where the Salmon River and Ponderosa Pine byways start. Salmon and Challis anchor the Salmon River byway, Arco fronts Craters of the Moon, and Kamiah holds the Nez Perce-Clearwater supervisor’s office at the west end of the Lolo country.
Book with the season. The northern roads are generally open July through September, and the Owyhee Uplands byway is closed from the first snowfall until Memorial Day weekend.
Nobody plans a trip around motels, and almost every long trip uses a few. After a week of wind, when the weather turns, while the truck is in a shop, or when the people you travel with have simply earned a hot shower.
What makes lodging work for overlanders
It comes down to parking and attitude.
01Room to park tall and long vehicles, and trailers without unhitching
02Parking you can see from the room, or that is lit
03Late arrivals and early breakfasts
04A hose, a laundry, and no fuss about dust
05Staff who know the local roads and what is open
Before you book
Call rather than click when you have a big vehicle.
01Ask about parking for your height and length.
02Ask about the access road in wet weather.
03Ask about pets, and about leaving gear on the vehicle.
Questions people ask
Will my rig fit?
Ask before you book. Roof tents, campers and high-roof vans do not fit many parking garages, and trailers need pull-through space. Small-town motels and lodges are usually easier than city hotels.
Is it safe to leave gear on the vehicle?
Use judgment, park where you can see the vehicle or under lights, and bring in what you cannot replace. Ask the front desk where they would park it.
How high is Idaho?
From Lewiston at 740 feet to Borah Peak at 12,662.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
