Consider Highway 20 a treasure map. But instead of gold, it points towards fish. The two-lane road traces a “smiley face” arc across Idaho as it connects Montana with Oregon, delivering anglers to more than a dozen high quality trout streams and trophy lakes. Follow this interactive map for the best that the Trout Highway has to offer. Then, check out The New Spirit of Fly Fishing, an interactive site we built in collaboration with Chevrolet Silverado to celebrate the sport’s renaissance.
