The route drawn on this API map is an approximation of the route that I rode. Neither Google Maps nor Google API Maps will draw a DRIVING or BICYCLING mode route from West Yellowstone to Gardiner along US287 & US89 during the winter because the roads are closed, they may(?) show that route during summer months. This map was drawn using the BICYCLING mode. Click on Park Roads - Yellowstone to get an open/closed status for the route.
