We will be staying at Columbia Falls for a week in September and plan to spend a day on the "Red Bus" tour of Glacier up to Logan Pass and back. We visited Glacier 30 years ago but did not go to Waterton on our way to Banff on that trip. We were thinking about going driving over to Waterton and I have two questions. Is it worth the effort to go to Waterton, and would it be entirely nuts to try to do a day trip from Columbia Falls to Waterton and back in one day? I think I know the answer to the last part of the question, but I still would like your opinions. Thanks!
