Pinnacle Mountain is the technical alpine climb (Alpine II, 5.5-5.6) located between the popular scramble of Mount Temple to the northeast and the smaller scramble of Eiffel Peak to the southwest in Banff National Park, one of four connecting national parks making up the central Canadian Rockies. Walter Wilcox named Pinnacle Mountain in 1894 due to the large pinnacles located to the north of Sentinel Pass. Pinnacle Mountain was actually originally named Sentinel Mountain. It was first ascended by Hickson, Feuz and Aemmer in 1909 and was considered quite the accomplishment for the period after three previous attempts failed.
There are two Pinnacle Mountains in Canada, one in Quebec and this one of the Canadian Rockies. The hike up the Larch Valley Trail is popular among hikers, but this climb is rather obscure. We were the first to sign the old log book in 2006 (June) and the last entry was August of 2005. The lone published route is the Alpine II, 5.5-5.6 route up Pinnacle Mountain’s southwest ridge which only involves two pitches of technical climbing. An old hemp rope was installed on the 2nd technical pitch many years ago, and only a small remnant is left. To date, there have been no other routes of interest on Pinnacle and it makes little sense to attempt to ski the mountain. Unlike other routes in the Selected Alpine Climbs in the Canadian Rockies guide book, i.e. Mount Brock, I found this route quite accurate via the grade and description. One move on the second pitch up a cold damp chimney might venture into the 5.7 realm (modern rating) and is difficult to protect. Pinnacle Mountain is quite loose in spots, but this is the Canadian Rockies.
One would be hard pressed to find a better summit to take in more immediate 11,000’+ mountains in the Canadian Rockies, including Mount Deltaform, Mount Lefroy, Mount Temple, Mount Hungabee, Mount Victoria and even Mount Joffre and Mount Hector in the distance. The “Valley of the Ten Peaks” views are magnificent, particularly the north face routes of Mount Fay.
Getting ThereThe Trans-Canada dissects Banff National Park east to west as you come in from Calgary. Travel to the Lake Louise exit and turn left through town and follow this road 2.5 km to the Moraine Lake Road. Turn left and proceed to the parking area at the Moraine Lake Lodge (dead end).
You will be required to purchase a national park pass as you enter Banff National Park coming from the east on the Trans-Canada. This pass is good for all four national parks. If you plan many visits to Canadian National Parks within one year, you should purchase an annual pass. There are no permit requirements to climb in Banff or Yoho National Parks, but all camping is regulated. There is also a backcountry permit required if you plan on spending a night in the backcountry versus the conventional campsites. This can be obtained via the parks website which is included in the camping section below. The huts are managed by the Alpine Club of Canada versus the Parks. The Alpine Club of Canada headquarters is located in Canmore, AB, the Banff National Park headquarters is located in Banff, AB and Yoho National Park headquarters is located in Field, BC. You will drive through the manned national park kiosks as you enter Banff National Park on the Trans-Canada.
This is active grizzly country, therefore, you should always have bear spray on your person during the non-hibernation periods. I advise checking with Parks Canada for any area and/or trail closures. THE LARCH VALLEY TRAIL USED TO ACCESS PINNACLE MOUNTAIN IS NORMALLY RESTRICTED DUE TO BEAR ACTIVITY.
