Formerly called the Clearwater Canyons Scenic Byway, Idaho's
Northwest Passage Scenic Byway is a 90-mile corridor through some
of the most scenic and historic country in the United States. The
Byway follows US 12 from Spalding along the Clearwater River to
Kooskia, Idaho. From there it follows Idaho State Highway 13 to
Grangeville.
The byway is located equidistant between Boise, ID, Spokane, WA,
and Missoula, MT in a region called North Central Idaho. Allow 1
hour and 30 minutes for a straight drive; however, if you want to
visit and explore some of the Lewis and Clark and Nez Perce
historical sites, give yourself more time.
