Lost Trail Pass is the only significant grade. It levels out at ~7000’. I don’t recall it being particularly steep on either side though. It’s mainly all two-lane as you go further down the Bitterroot Valley. Slow down for all of the small towns. They make good speed traps.
Correct. The climb up to Lost Trail Pass from the valley can be considered steep for some, but it's gradual and winds around to control the ascent angle. Same coming down the other side. If you don't have the power to make it up or down, this will make you nervous, otherwise, it's a beautiful pass.
I always check out passes in my Mountain Directory West and on YouTube. Here's a
link to a video on Lost Trail Pass, but there are others.
