Cowichan River Provincial Park stretches along the Cowichan River on Vancouver Island in British Columbia for almost 20 kilometres, from Lake Cowichan to Glenora south of Duncan. Covering 1,418 hectares, it protects an extended river corridor rather than a single compact area. Its most distinctive feature is the Cowichan Valley Trail, which runs the park’s full length and also forms part of the Trans Canada Trail. The park is important for combining a protected river landscape with a continuous trail route, serving as both a natural corridor and a recreational route along one of the region’s main waterways.
