The Hells Canyon Scenic Byway runs through the eastern rift that creates the boundary between Idaho and Oregon and offers amazing views of the canyon. Hells Canyon National Recreation Area features basalt cliffs that are a striking black and green color and sandy beaches along the Snake River. Visitors will have the opportunity to see Hells Canyon Dam along the Byway and can even stop and take a guided float trip or boat along the Snake River below. Hells Canyon Road is a steep, narrow road with a lot of curves and only two lanes. Drivers should be cautious and make sure to fill up on gas and emergency supplies before traveling this road.
