Jasper and Banff in three weeks without reservations

If you do not have reservations in Banff or Lake Louise,
I would suggest trying to find something in Canmore.

Last week the road up to Lake Louise had to be closed due to heavy traffic
and no parking. Unfortunately there is very little as far as RV parks
because it is all parkland and not privately owned.

It would be the same if you were heading to Jasper.
