Detailed road trip table:

The entire trip spans 450 miles and takes 7-8 hours of pure driving time. However, with stops for sightseeing and rest, plan for a full day. The route is primarily on interstate and US highways, with good pavement and regular maintenance.

Key highways: US-91 from Logan to I-15, I-15 north to Idaho Falls, then US-20/US-26 west to US-95 north, and finally US-12 west to WA-195 into Pullman. Alternatively, stay on I-15 to Missoula then US-12 West; this adds 30 minutes but avoids Idaho's narrow mountain roads.

Tolls: None. Fuel costs: Expect $50-70 for a typical sedan at current prices. Gas stations are plentiful in towns like Pocatello, Missoula, and Lewiston, but sparse in between (e.g., Lolo Pass). Fill up when you can.
