Surprise Pass is a very popular ski tour in the Lake Louise area that offers 600m of fall-line skiing. Its NNW aspect often holds cold and dry snow.
From the Lake Louise parking area, walk towards the Chateau and follow the signs for Saddleback Pass/Fairview Mountain. Once near treeline, the terrain will begin to open up. Cut across the base of the south face of Fairview Mountain. You will have to cross some steep, high consequence avalanche paths. You will eventually have a short but steep descent into the moraines. Continue heading west until you see the pass. You will pass a couple of couloirs looker’s right before reaching Surprise Pass. After enjoying the 600m ski down, head towards and across the lake.
