On Saturday, June 15, 2013 I took my family up King Creek Ridge for a pleasant hike in beautiful spring weather. We followed a good trail right from the parking lot and had no issues other than the tiny moderate scrambling step just before the true summit of the ridge which Hanneke didn't bother with and Niko didn't really appreciate (but he did it!!).
On a early (0430) August 6 2005 morning, I joined Dave Stephens and Blair Piggot on a full day trip to scramble Mount Smuts and The Fist in Kananaskis Country. Blair and Dave do a lot of mountaineering and climbing trips together and every once in a while Dave manages to sucker Blair into a scramble.
If you're doing Sarrail as a day trip from the Upper Kananaskis Parking lot, you are in for a fairly long day. The hiking and scrambling are fairly easy though, so it's doable for fit and fast parties. We did this trip on our way into the Aster Lake area for a few days of peak bagging the Kane peaks.
