Alexander Mackenzie Provincial Park. Mackenzie did not know that he arrived just a few weeks after Captain George Vancouver visited Dean Channel and North Bentinck Arm. The town of Bella Coola is at the head of North Bentinck Arm; Bella Coola is an English adaptation of the Heiltsuk name for the Nuxalk (whose name in their own language means the Bella Coola River and its valley). Bella Coola is the only community on the coast between Vancouver and Kitimat, to have road access to the rest of the province, via British Columbia Highway 20 to Williams Lake via the Chilcotin region.
