Hwy 12 from Kooskia,ID to Missoula,MT

As others have noted, there are no hard pulls, highway follows the river until just before Lolo Pass which is about a one mile easy pull up to the top. When you get to the top of the pass, make sure to stop at the visitor center and check things out and take a break. As you're driving eastward from Kooskia towards Missoula, pull off the highway once in awhile and walk over to the river, it's really something. Clear water and beautiful scenery. Stop at DeVoto Memorial Cedar Grove and if you want a good campsite, the Wilderness Gateway CG can easily accommodate your outfit. Have a good trip and pull over once in awhile to let other cars pass. About 50mph and you will be able to enjoy the road and look around too.
