Resplendent Mountain, Mountain summit in Mount Robson Provincial Park, British Columbia, Canada

Resplendent Mountain is a peak at the northern end of Mount Robson Provincial Park in British Columbia, part of the Rainbow Range and a sister peak to Mount Robson. Its east face rises above the sources of Resplendent Creek, which feeds the Moose River, while its north face emerges from the Robson Glacier, whose meltwater flows into the Robson River toward the Fraser River.

The first ascent was made in 1911 during the same trip on which Conrad Kain scouted the routes later used for the first ascent of Mount Robson. Arthur O. Wheeler had earlier described the east face as clad top to bottom in pure white snow, and the name, given by Arthur P. Coleman, was immediately apt.

Arthur P. Coleman named the peak, and Arthur O. Wheeler described its east side as clad top to bottom in pure white snow, so brilliant in sunlight that the name's aptness was immediately apparent. The mountain is a sister peak to Mount Robson, its nearest neighbour, and the pair form a panorama seen from Via Rail trains and Highway 16.

Climbers typically reach the summit via the Robson-Resplendent Col route on a roughly 29-kilometer journey with about 2,600 meters of elevation gain. The terrain is demanding and requires glacier experience plus favorable weather conditions.

Peter L. Parson made the first solo ski ascent in 1930, and the peak became a sought-after winter objective. A ski descent runs over 1,800 metres from the summit to the toe of the Robson Glacier.
