A once-in-a-lifetime adventure is to snowmobile along the same roads traveled by tourists in the summer time. There are 200 miles of groomed trails inside the park. All roads except Mammoth to Cooke City and Canyon to Tower are open to snowmobiles. Ride from West Yellowstone to the Grand Lower Loop, which takes you to Old Faithful, Yellowstone Lake, Norris Geyser Basin and many other of the park’s favorite attractions. Please see THINGS TO KNOW regarding special restrictions for riding in the Park. Daily tours to Canyon and Old Faithful are available to everyone. The Lower Loop tour is for experienced riders only, with no double riding.
