2. Going To The Sun Road, Montana, USA
In the spring months, the Going To The Sun Road is open exclusively to bikers and walkers, and the lack of motorists dramatically improves the experience of exploring Montana’s Glacier National Park. The full route is 50 miles long (if the snow has all been ploughed), and highlights include the highest point Logan Pass, the Weeping Wall (which is very popular for a dramatic photo), Wild Goose Island Viewpoint and McDonald Creek. In the spring biking season, a shuttle helps ease congestion, taking bikes and riders from Lake McDonald Lodge to Avalanche. With over 59,000 Instagram posts tagged with #goingtothesunroad, the route has nearly 733 photo shares per kilometre.
