Lake Louise serves up the most terrain in the Canadian Rockies and from time to time gets some good dumps of snow as well. This is where most people from Calgary come to shred along with many of the people staying in Banff, so it can get busy on the weekends. The mountain has three different areas to choose from, all offering up something different, allowing you to escape the crowds even on the busiest of days.
The front side of the mountain is where the majority of the crowds stick, it is wide open up top and for the most part groomers with the majority of the trees being to tight to ski through. The back side is where things get serious with quite a few rocky chutes off the top opening up into some lengthy bowls, wide open powder fields and even some good tree skiing towards the southern end of the ridge line. Larch area is the third part of the mountain, it is on a different mountain than the other two areas, and has some good tree skiing and mellow runs if you are looking for that sort of thing. If you are here in the early season or the base isn't that deep be very careful about rocks on the top and on the backside as they are everywhere, if you see an exposed rock chances are there are probably some hidden around it as well.
