Hells Canyon Scenic Byway - Idaho
22 miles - Allow 45 minutes each way.
The Hells Canyon Scenic Byway winds its way along the east side of this massive rift that separates Idaho from its neighbor, Oregon. While the view from the road is breathtaking, a guided float trip or jetboat tour is a must. Towering cliffs of black and green basalt hang so high above the Snake River and its sandy beaches that boaters strain their necks to see out in places.
