Heard good things about Kicking Horse, given we are on foot with no rental car is it easy to get from Banff to there? Also what kinda costs would we be looking at? Given we've already brought a tri pass I'd have to do some serious selling to my friend to get him to buy in to it when he's moaned at paying 1K for what we have now!
I'm sure there are buses available to Kicking Horse, Revelstoke, Fernie, etc. Wouldn't be a day trip though you'd want to do a couple days.
Passes are available at Costco near the airport in Calgary, although if you're 100% on public trans you may be shit out of luck...
