Walking & Standing
Most sightseeing activities involve leisurely to moderate walking at attractions, scenic viewpoints, museums, historic districts, and cultural sites.

This itinerary includes three longer travel days with approximately four hours or more of driving, including sightseeing stops, between Yellowstone and Sun Valley, Sun Valley and Boise, and Boise and Lewiston. Travelers should be comfortable spending extended periods seated on a motor coach. The Hells Canyon jet boat excursion travels at high speeds through occasionally rough water.
