We are thinking of visiting GNP in late September. Is that too late? We will mostly be driving and taking short hikes and are concerned about the weather and road condition.
Any advise or insights are greatly appreciated.
You should be just fine. Just pack a couple extra layers to have handy if you need them. The colors should be changing so it should be quite pretty. You have a rare chance of finding weather but I would put that under extreme rare. You are visiting a beautiful place!
