The Trail Creek Scenic Drive, which runs between Mackay and Ketchum, connects the Lost River Valley with Sun Valley. The drive winds through the Sawtooth Mountains for about 40 miles through scenic forests, meadows, and mountains, offering spectacular views of the surrounding landscape. There are several hiking, fishing, and wildlife viewing opportunities as the road passes through the Sawtooth National Recreation Area. In fall, when the trees turn golden and red, nature creates a breathtaking display of colors.
