We were in Banff last September and stayed at both Two Jack Campgrounds. The Main was nice and quiet and offered a decent sized campsite for our 23' International. The Lakeside campground was even nicer as they have several lake view sites. The Lakeside fills up early so reservations are recommended. They do offer first come first serve but you need to get in line at 7:00AM to get a site if you don't have a reservation. We went all the way up to Jasper and would highly recommend the drive up to Jasper along the Icefield hwy. it was spectacular. We also went to Waterton Lakes which is the Canadian Glacier Park extension. Very beautiful and scenic.
Enjoy you trip,
