The Energy Loop: Huntington/Eccles Canyons Scenic Byway is a National Scenic Byway in the state of Utah. It spans approximately 83 miles as it travels from Fairview through the Manti-La Sal National Forest southeast to Huntington via Huntington Canyon, and northeast to near Colton via Eccles Canyon.
The south branch continues to follow SR-31, climbing up to over 9600 feet elevation before dropping down to the east-southeast as it passes Huntington Reservoir, Cleveland Reservoir, and turning to the northeast towards Electric Lake. At this point, the route turns to the southeast, following Huntington Canyon and Huntington Creek downwards, eventually exiting the national forest and the canyon and ending in the city of Huntington, a mile southwest of Huntington State Park.
The east branch turns onto SR-264, which travels eastward towards the north end of Electric Lake, where it turns north to go up Upper Huntington Canyon. After about 3 miles, the route turns east again and climbs out of the Upper Huntington Canyon, and crosses over to Eccles Canyon, following Eccles Creek down. After about 6 miles, the canyon and the route turn back to the north again, passing through the town of Scofield, and passing by Scofield Reservoir and state park. It continues on past the north end of the reservoir for a few more miles before turning to the east yet again, ending in Spanish Fork Canyon near Colton.
This route was designated a Utah Scenic Byway in 1990, a National Forest Byway on February 6, 1991 (as Huntington Canyon Scenic Byway, Eccles Canyon Scenic Byway), and a National Scenic Byway on June 15, 2000.
