For families, the Shoshone Falls in Twin Falls (nicknamed 'Niagara of the West') and the California State Railroad Museum in Sacramento are excellent. Pets are welcome at most rest stops and many hotels, but call ahead.

Climatically, expect extremes: cold in Montana, hot in Idaho/Nevada, and mild in California. Always carry water and sunscreen.
