Did this right before the pandemic... traveling west to east.

Stayed off 2/90.

Did the Okanagan Ghost Town/Old Skagit Mental Institution route. (HWY 20) Old Wauconda Museum is highly recommended.

Super enjoyed Republic and the Kettle Range.

Caught up to HWY 2 in Idaho. Do the Suspension Bridge.

Took 37 north from Libby MT. There's an Air Muesum out there that you have to make a reservation for. Worth it.

Caught GNP the second full week of June. Going to the Sun road had fully opened the week before. Absolutely marvelous. BUT! The trails were still snow-covered at the pass.

Then, I did the Montana ghost town (Garnet, but there are others) route, driving through Missoula and taking HWY 12 east to west.

The only hotel reservation that I made in advance was for Kalispell as hotels fill fast around GNP. Everywhere else was the day of.

My spouse and I did it as a road trip and enjoyed ourselves immensely.
