Stay away from Bee Hunter Trail as it is the seems to be the most popular for snow mobilers. I think the Summit Trail is the best for winter, it is next to the best sledding hill in the park as well as the Art Roscoe X Country ski center. It has the added benefit of having showers which some of the other loops do not have. All the cabins on Summit have two bedrooms with four beds but we have easily fit six. We were there after Christmas, no snow while we were there but since they have had quite a bit. At least a foot in the southern tier today alone.
