This trail is 15.7 miles in length and is commonly referred as the backbone of the American Fork Canyon trail system, because it connects several loop routes along the northern portion of the district. The most popular region of the Ridge is from the Summit TH to the junction with the Mill Canyon trail #040. North of Mill Canyon, the trail becomes progressively more difficult, with areas of steep grades and exposed sections of trail. This trail has excellent views throughout. Users can take this trail as far as the Alta/Brighton area.
