Billings Montana to Yellowstone

[wtmtnhiker]

I'll be driving from Billings, Mt to Grizzly Rv park in West Yellowstone. Looks like the most direct Route is I-90 to U.S.191. Does anyone have firsthand knowledge of 191? Is it a decent road to drive an RV to Grizzly? Any formidable grades up or down? Thanks.

Thanks for the replies. I'll take 191 then.

Used 191 couple years ago and it’s a good US highway.

I don't remember the route numbers but, Billings to Bozeman to Ennis and then south to West Yellowstone. It's just a little longer but the road is less crowded and fewer curves.

Been a while, '08 IIRC, we did it in the reverse, West Yellowstone to I-90 on our way to Glacier, no problems that I can remember, decent road with no severe grades.
We even saw moose on that route, which we never did in Yellowstone or the Tetons.:)
