From red rock canyons to alpine forests, the scenery shifts dramatically. The Virgin River Gorge is a highlight, with hiking and photography spots. Near Beaver, Utah, pull off for the historic Cove Fort. In Idaho, the Snake River Plain offers vast farmlands. Jacksonville itself is a gold-rush era town with a preserved historic district. Browse antique shops and art galleries. For food, try the smothered burritos at El Farlito in St. George or the huckleberry pie at Willow Wind in Beaver.

Road quality is excellent on interstates, but watch for wildlife near dusk. Rest stops every 30-50 miles. For families, the Children's Museum of Utah in Provo and the Discovery Center in Boise are great. Pets: many chain hotels like La Quinta accept pets; rest areas have designated pet walks. To manage fatigue, stop every 2 hours. The Tabiona Rest Area near Nephi, UT, has scenic views and clean facilities. Hidden off-route: Cedar Breaks National Monument, 20 miles east of I-15, is a less-crowded Bryce Canyon.
