There was a summit register in 2006 and I was the 6th sign in for the summer (August) proving this is a relatively popular objective. For good reason. The 360 degree views from Redoubt Mountain represents one of the real sweet spots in Banff National Park. The views of the east ridge route up Mount Temple are 2nd to none. All of the Valley of the Ten Peak mountains are in clear view. Of course Mount Hungabee, Mount Lefroy, Mount Victoria and the Louise group in general are unambiguous as well from this vantage. Not to mention Niles Peak, Mount Daly, Mount Balfour and other summits towards the Icefields. Closer in you have Mount Bonnet and its glacier, Fossil Mountain, Mount Bride, Mount Douglas, Pika Peak, Ptarmigan Peak and Mount Richardson and its glacier.
There is no question you are tempted to descend via a ridge back south towards Lipalian Mountain which overlooks the ski resort, but without a rope and plenty of pitons, it would be a foolish endeavor. Descend the route, utilizing the one shortcut I highlighted above. I took 7 hours to complete the route, but was moving fast and solo.
