Robson River

The Robson River begins in Robson Lake, which is located at the toe of the Robson Glacier. After exiting the lake, the river flows northwest then southwest before entering Berg Lake. Before entering Berg Lake, the river widens and splits into many small streams before flowing into the northeast end of Berg Lake.

The river exits the southwest end and flows west for about 2.3 kilometres (1.4 mi) until dropping over spectacular Emperor Falls, a 46 metres (150 ft) plunge at the head of a 1.6-kilometre (1.0 mi) canyon in which the river thunders over two more waterfalls. The first is Falls of the Pool, which comes about halfway down the gorge and at the end of the canyon is White Falls, a multi-tiered waterfall that cannot be seen in its entirety from the main trail. All these falls are collectively known as the Valley of a Thousand Falls. The river continues south from White Falls for another 3.3 kilometres (2.1 mi) before entering Kinney Lake, which sits directly at the base of the Robson River's namesake peak, Mount Robson. Between Berg and Kinney Lakes, the river loses 666 metres (2,185 ft) of elevation, much of which is lost in the gorge between Emperor and White Falls. Once again, prior to entering another lake, this time Kinney, the river spreads out very wide & divides into many braids before flowing into the lake.

The Robson exits Kinney Lake at its south end and flows southwest for about 7.3 kilometres (4.5 mi) to its confluence with the Fraser, about 3.5 kilometres (2.2 mi) below Overlander Falls and about 1.7 kilometres (1.1 mi) above the mouth of Swiftcurrent Creek. About halfway between Kinney Lake & the Fraser is Knowlton Falls, the first waterfall seen on the Berg Lake Trail. About 0.6 kilometres (0.4 mi) above the Fraser, the Yellowhead Highway crosses the river.

In total, the river loses 869 metres (2,852 ft) of elevation between Robson Lake and the Fraser River, three-quarters of which is lost between Berg and Kinney Lakes.
