I'm not a total die-hard, but I love Lake Louise. I had the pleasure of going a couple of times while visiting family in Calgary. My wife prefers easy runs, I like the diamonds... There's plenty of both at LL. Love it.
Having put in about 300-350 days skiing at Lake Louise, I'm a pretty big fan. Especially the smell of Larch trees up at the Lake. One thing that's escaped me is a backcountry trip from Temple MTN to Skokie Lodge. Love to hear from anyone who's done the trek.
