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.
We arrived at the Upper Kananaskis Lake parking lot early in the morning on a gorgeous, clear day on September 5 2006. After struggling into our heavy backpacks, we proceeded around the first few kilometers of Upper Kananaskis Lake before cutting off on a 'hidden' trail towards Hidden Lake. You may have a tough time finding the trail to hidden lake but look carefully at the map and the GPS track and you should be able to find it.
After following a somewhat rough trail to the lake, we were delighted to see that its shoreline was dried back many meters, allowing for easy passage along it. Even though a trail has been cut around the east shore of Hidden Lake, it's much easier and more pleasurable to hike alongside it in the open.

[Rod and Vern are very glad to be hiking along the shoreline of Hidden Lake rather than bushwhacking around the east side of it.]

From the south end of Hidden Lake we followed bits of trail through light forest and then cairns and trails up a steep scramble through the headwall along Foch Creek and past the impressive Fossil Falls. This section should not be under estimated! With heavy packs on and pebbles-on-slab terrain, it felt exposed in places. I could see some folks turning around here - especially if they don't have proper hiking boots and poles for stability.
[After Hidden Lake we started up more 'scrambly' terrain towards and through the headwall along Foch Creek.]
[Do not under estimate the headwall. It's loose and exposed in places and much harder with snow (as we had when we approached and climbed Joffre in June 2014.]
[Vern and Rod come up the headwall with Hidden and Upper Kananaskis Lakes in the bg.]

[Rod delicately balances over a moderate scrambling section of the headwall. This is tricky with a large backpack on.]
[Gorgeous views from the upper headwall back over our ascent route - note the trail in the scree to the right.]
[A good trail continues from the top of the headwall high above Foch Creek, which is oos to the right.]
[We dropped our backpacks near this dried up tarn before going back down the trail 5 minutes and then turning up the westridge scramble route on Sarrail. We could have gained the westridge sooner but this worked.]
After dropping the big packs and drinking some much needed Gatorade we put on our small and light scrambling packs and backtracked along the trail towards Mount Sarrail. We only had to backtrack for about 5 minutes before spotting an obvious grass / slab gully giving us access to Sarrail's lower slopes. On hindsight we should have hit the main west shoulder sooner, but we traversed below the ridge for a while before finally heading up to the shoulder and finding the proper trail.
Mount Sarrail is not a technical peak and the west ridge was delightful scrambling, but after climbing almost 500 meters vertical with big packs under a warm sun, the extra 1000 meters were a bit of work. :) There are a few easy down climbs along the ridge but no major difficulties.
[Jon on the easy west ridge of Sarrail.]
[There is a good trail beaten into the scree. The only scrambling section other than the approach headwall is just above Jon here.]
[Gorgeous views back down the west ridge with Warrior, Waka Nambe, Aster Lake, Onslow, King George and the Royal Group, Northover (L to R) visible.]
[Vern and Rod on the west ridge with Aster Lake and Creek to the left.]
[Great view over Aster Lake and Creek of Warrior Mountain and its striking appendage, Waka Nambe.]
[Great views of the ridge of Rod coming up to the scrambling section.]
[The down climbs aren't an issue if you're used to scrambling and have dry conditions like we did.]
The summit views were spoiled a bit by smoke but we enjoyed the summit in windless, sunny, warm weather.

[Mount Nivelle and the Castelnau Glacier are barely visible through the smoky haze. Other peaks around Nivelle include, McCuaig, De Gaulle, Castelnau and Ney.]

After almost an hour on the summit it was time to head back down and finish our backpack into Aster Lake. The descent wasn't an issue and we followed obvious trails and cairns back to the Aster Lake / Northover Ridge trail before turning back to our packs near the dried up tarn and continuing towards Aster Lake.

[With lots of snow or ice this section would be trickier but for us it was literally a walk in the park. :)]
[Stunning views of the west ridge, including this one towards Mount Lyautey (R).]
