re: Bozeman or Jackson hole for visiting Yellowstone?

The park is at higher elevation than the surrounding areas. And that’s true if you come down from Bozeman or drive up from Jackson. I would expect some snow, and relatively few people. It’s still a early enough that all the roads should still be open.

By the end of the month roads do close, and some stretches are limited to vehicles with snow tires.

October just isn’t the prettiest time of year. But you’re still in an amazing place.
