We took the Snow Coach tour two years ago. We went out of Jackson Hole, WY. They picked us up at the Lodge and took us to Yellowstone's West entrance where we switched over to the snow coach. It was a great way to see Yellowstone in the winter. We were on the Old Faithful tour. It was a full day trip with lots of stops for photo ops. And the stop at Old Faithful lodge where we had lunch (sandwiches/burgers nothing special) which was part of the tour. Then we went thru the gift shop and then watched as Old Faithful sprang to Life. It was a great day. Be prepared to take some water on the tour as there were only two stops where anything to drink was available. Lunch and a place where there was a cabin with bathrooms and some hot springs that were cool to see. And the spot where you switch from the bus or van to the snow coach at the beginning and end of the tour had food/drink and bathrooms.
We saw lots of bison, some moose, elk and birds. There was not a lot of wildlife out moving around. It was 20 below the day we went so be prepared to dress in layers. I highly recommend the tour. Most roads are closed in the winter time, so all the tours pretty much go to the same areas. We had considered doing the snowmobile trip, but it was way to cold and long a trip
(90 miles round trip) so we opted for the snow coach instead and were really happy that we did.
