Terry Dolan’s snowmobile tour covers more than 150 miles and takes in the major sights along the lower section of the park’s Grand Loop Road, including Yellowstone Lake, Old Faithful, Fountain Paint Pot and the Lower Falls of the Grand Canyon of the Yellowstone River. For adventurous travelers, the trip offers an exhilarating and often thrilling way to tour the park, with a small group of good riders able to quickly stop and hop off their sleds for photos or sightseeing before pushing on to the next landmark.
