Jasper/Banff are typical tourist towns - beautiful scenery, lots of wildlife, lots of giftshops, lots of campgrounds.
If you go to Jasper, ask a local about cliffdiving. There are some awesome spots to cliffdive, ranging from a 3m jump to like 50m+ in a beautiful blue glacier lake.
The cliffs I went to were near the falls in Jasper, I forget the name of the falls.
Anyway look that stuff up if you head that way. Cliff diving is probably the best part about Alberta in the summer.
