Mount Tyrwhitt: Summit Scramble in the Canadian Rockies

Why Visit Mount Tyrwhitt

Mount Tyrwhitt rises prominently above the Spray Lakes Reservoir in the Canadian Rockies, delivering 360-degree views that stretch from the Opal Range to distant peaks in British Columbia. Its accessible scramble makes it a favorite for hikers seeking a moderate challenge without the crowds of more famous summits nearby.

The Hike to the Summit

The standard route begins near the Mount Tyrwhitt trailhead along the Smith-Dorrien Trail. Hikers follow a well-defined path through subalpine forest before emerging onto open slopes. The final push involves straightforward scrambling over loose rock and scree to the 2,881-metre summit. Expect a round-trip distance of roughly 8 kilometres with 700 metres of elevation gain. Strong hikers complete the outing in four to six hours.

What to Expect at the Top

From the summit cairn you can identify Mount Rae to the north, Mount Sparrowhawk to the south, and the distinctive profile of Mount Assiniboine on clear days. The broad summit plateau offers sheltered spots for lunch and photography.

Getting There

Drive south from Canmore on Highway 742 (Smith-Dorrien Trail) past the Spray Lakes Reservoir. Parking is available at the signed pullout for the Tyrwhitt trail. The road is gravel in sections and suitable for most passenger vehicles in summer, though winter access is limited.

Best Time to Visit

July through early September offers the most reliable snow-free conditions and long daylight hours. Wildflowers peak in late July. Shoulder seasons bring colorful larches in September and quieter trails, but expect possible morning frost. Always check avalanche and weather forecasts before heading out.
