Jasper and Banff to Glacier NP

I did that trip many years ago and the weather was great so we saw it all. You are in for a treat: the Canadian Rockies are majestic...just pray for good weather. On a second trip there a few years later it was socked in and rained the whole time...could hardly see the peaks..we might as well have been up the Bogachiel during a monsoon. We beat feet south and didn't get out of the rain until we were below Glacier.

Suggestion: cross over at Sumas rather than at Blaine to get you further east of Vancouver.
