From the forested hill and mountain country of the northern panhandle to the broad high country deserts of the south, Idaho is home to diverse landscapes. Follow the Oregon Trail into southern Idaho, where Register Rock, near American Falls, records the names of some of the pioneers. In southern Idaho, visitors can enjoy the refreshing waters of Bear Lake, brave the whitewater on the Snake River, or visit Arco, the first town in the world provided with electricity from nuclear power. During summer, the experimental reactor that produced that power can be visited.
