Best route to Grand Teton NP Yellowstone NP & Glacier NP

[Tnedator]

We are also looking at making a trip to Yellowstone, as my wife has never been and then possibly up and doing a loop of Utah National Parks.

Is there any time better than others in terms of crowds, but still decent weather? I've heard the crowds at Yellowstone and other national parks is crazy, compared to what it was like a few decades ago (last time I was at Yellowstone was '89).

Avoid time between labor day and memorial.

The difference in crowds is significant.

Is late Sept through mid Oct doable, or too late in the year?

We were in YNP and general area in Sept a few years ago - not sure what temps you are accustomed to, be sure to look up average temps by month. When we were there, couple mornings had a dusting/light snow.

As long as the parks were open, I think I would take cold and light snow over hours of waiting.

We usually hit ynp in late Sept to early October. Freezing at night 30 to 60 during day, and lots of wildlife. I consider it ideal. Just watch weather reports when determining exit routes.
