Any advice on weather likely to encounter on this trip?It travels over a large area,with varying altitudes, so seems different kinds of clothing may be needed.
Layers are best, it may be cool at the start, but, should get warmer as you go south. Having said that I went in October and the morning at Little Big Horn was warm, but, the weather got worse going towards Yellowstone, and it was cold and rainy in Cody.
Although it snowed overnight, Yellowstone was sunny and warm although the road to Jackson was blocked, we stayed overnight in West Yellowstone and went back into the Park the next day,by the afternoon, the road to Jackson had cleared so we weren’t held up.
