  Highlights
  This scramble offers great views from the open ridge all the
  way to the top. Great views of the Upper and Lower Kananaskis Lakes. Many people like
  doing this one more than once (not to mean the same day though).
  Getting There
  Head west out of Calgary on the TransCanada highway # 1 for
  79km (49.4 miles) and take the Kananaskis Country highway # 40 turnoff and head south. If
  your base is Banff head east on the TransCanada for 52km (32.5 miles) and turn south on
  route as above. Drive south for 49km (30.6 miles) and take the right hand turn into Peter
  Lougheed Provincial Park. Follow this road for 15 km (9.4 miles) to the Upper Kananaskis
  Lake parking lot. From this lot looking north you can see the long ridge on Mt.
  Indefatigable.  
  Route Description
  From the parking lot head counterclockwise around the lake.
  After a few minutes of walking you will see a trailhead heading into the trees to the
  right. Take this trail as it heads through the forest for 20 minutes or so and gains the
  open left side of the ridge. In another 20 minutes or so you gain the ridge proper where
  there is a bench and the beginning of some great views. The way is obvious as you continue
  straight up the ridge with a big drop-off on your right. The ridge is really wide so just
  steep hiking here. Just as you make it to the top of the ridge and the incline levels off
  you take the first trail to your left. If you look straight up at this point you can see
  the antennae at the south summit. Follow this trail generally heading in the direction of
  the summit. When you reach tree line the trail climbs diagonally left to a rock rib that
  comes halfway down from the summit ridge. Continue on and then to the left of this rock
  rib and then traverse a short distance left again to gain the summit ridge. A nice plod to
  the top is all that remains. Return the way you came.  
  This peak was my first scramble and at that time the upper slopes were
  covered with a half a foot of snow. We definitely missed the easier route. Our group went
  straight up towards the summit and let me tell you it got pretty steep. When I got home my
  mind kept replaying possible mishaps on a slope like that. Some how I continued my
  scrambling career and it was nice to later discover an easier route to the top.
