The narrow Fraser River canyon contains British Columbia's largest river, two transcontinental railways, and the Trans-Canada Highway. It travels through some of British Columbia's most striking scenery.
The region is serviced by the Trans-Canada Highway 1 which runs north-south in the canyon. Provincial Highway 8 runs west from Merritt and joins the canyon at Spences Bridge. Provincial Highway 12 travels northwest from Lytton and joins Highway 99 at Lillooet.
