Lewiston to Lolo pass highway 12 road questions

We've taken that route many times usually coming home from Yellowstone working our way back down through Oregon and back to So. Calif in our class A.

95% after you pass Lewiston is meandering road about 45 mph. The only steeper section is going up the Lolo Pass as you enter Montana but it is not bad at all. It is a very pleasant drive and we think well worth it. Toward the Montana end at the start of the pass is a campground called Powell. It has electricity and is on the river. If you time it right and want to camp there you'd hit no traffic going up the pass the next morning.

Take a look a the Mountain Directory - West. It will give you information about steep grades and curves for your route.

Downshift BEFORE you start gaining SPEED

Use brakes sparely
STAB them and quickly scrub off speed (reduce by 10 mph) then GET OFF THE BRAKES

Repeat as needed to maintain downhill speed


Uphill.....grear down and use higher RPM
Stay in right lane and don't expect ahny spped records

Agesilaus, thank you for your reply

Know how to downshift. We went up that way and it's a fantastic scenic route. It follows the river for much of it and kayakers and bicyclists are all around. At least during normal times. We had no problems with the truck and while there are grades I don't recall any extreme climbs or drops. IIRC the road climbs steadily for the whole first section.
