Northwest Passage Scenic Byway
Retracing the Lewis and Clark Expedition

Departure: Lewis and Clark Discovery Center, Idaho
Destination: Lolo Pass Visitor Center, Idaho
Time to allow: 1 day

The United States was 26 years old, small and itching to grow when President Jefferson persuaded Congress to let Lewis and Clark explore the new uncharted Louisiana Purchase and land beyond. Visitors can experience a sense of discovery as they travel the byway which parallels the Lewis and Clark National Historic Trail. Interpretive and visitor centers available at three locations show what the Expedition found in north-central Idaho. In addition, travelers can visit unstaffed Lewis and Clark locations such as Canoe Camp and Long Camp where the Expedition was halted for a month due to snow on the mountains. Or, visitors can see for themselves what Lewis and Clark saw by taking the scenic drive along the Clearwater and Lochsa rivers and walking through cedar forests. Distance, 170 miles; overnight in Kamiah; top off your gas tank there; ideal time of year is May to September.

    The road parallels the Lochsa Wild and Scenic River. The actual Lewis and Clark National Historical Trail, which is on a tree-lined ridge just north of the Lochsa River, represents the most difficult part of the Corps of Discovery's trek across the western territory to discover a passage to the Pacific Ocean. After Lowell, the road begins to narrow as the river canyon deepens and the speed limit is reduced to 50 mph. This portion of the highway is relatively young having been completed just 50 years ago in 1962, finally providing a connection between Idaho and Montana. Portions of this section of highway were constructed with manual labor from the World War II Japanese Internment Camp that was located at Canyon Creek. The road is narrow and winding but suitable for all vehicle types. Because the road shoulders are narrow, bicycling this section of the byway is not recommended. Services: Seasonal lodging and food at Syringa and Lowell, Year round lodging and food at Powell. Numerous tent and RV camping opportunities.
