Big Sister is the highest among the three sisters, and also
the highest point in Canmore.
The approach is from the back of the mountain. From the small
parking area, the trail angles up facing a visible summit
then crosses a rock fall on the left, before entering the
forest.
(1) After a steep, short hike through the forest, scrambles
begin.
(2) This part must be the downclimb mentioned on the scrambles
book. I would give it a five point one rating. It's a wall,
but as you can see we descended it facing forward.

We had a little bit of second thought taking this steep, snowy/icy
route. But we were very close to the top so we did it.
