We took a winter trip to West Yellowstone, Montana, and explored Yellowstone National Park by snowmobile. During the winter, roads are snowed over and entry is only permitted if you’re part of a guided tour or have a permit along with a snow-capable vehicle. We enjoyed two, full-day, guided tours with Two-Top snowmobiles out of West Yellowstone. It was a great way to see the park without the common crowds of summertime. Super stoked about it!
