USA/WY: Yellowstone NP – Snowmobiling with Bisons

Exploring the Yellowstone National Park by snowmobile, you ride from the town of West Yellowstone and make a giant loop hitting all the major geyser basins. Bison and other wildlife concentrate near the hot springs in winter and the wildlife sightings are amazing. And there are plenty of these massive mammals on the road; they always get right of way.
