A buddy and me will be flying into Billings, MT from the East Coast in late September to do a 5 day road trip through Montana, Northern Idaho, and finally Seattle. We will spend 2-3 days getting from MT to Seattle (typically a 12 hour drive) to allow us to do as much exploring as possible. A day in Seattle is all we really need since we are more interested in seeing the wilderness than cities.
The area that is of particular interest to us is the Lolo National Forest in Western Montana. I realize that 90 is the main interstate route through here, but we are looking for suggestions on even more scenic highways or roads that you can take through this area.
Also, does anyone know of any hiking, fishing, or white water rafting outfits that service tourists? We are not experienced in the wilderness and out in bear country the last thing we need is an encounter (excuse my ignorance, it's just something I wouldn't want to risk exploring the forest on our own).
Any other suggestions on famous towns and restaurants along the way would also be helpful.
