We're visiting the Rockies in a couple of weeks. For five nights we will actually stay at Lake Louise (the actual lake), and I'm reading reports of how bad the traffic is on the road leading up to it. And I'm scared because we will have to go up this road, at the very least, five times. So I'm wondering when in the day would it the road clear on the way up to the Lake - 5PM, 7PM, etc. Just so we can plan our days in the park and try to avoid traffic on the way back to our lodge.
