Big mountain, lots of options
Snow report always shows more snow than what actually falls
Lake Louise is a great mountain for intermediate skiers and/or families. Lots of terrain options and great lift access. However if you're looking for deep snow and advanced terrain there are better and cheaper options within 1 hr drive. The last straw for me was the constant lying on their daily snow report. They consistently report +5 cm more than what actually falls.
The best terrain is on the backside and Larch, or hike to the summit from the platter.
