Lake Large lake on Vancouver Island popular for recreation
A long freshwater lake on Vancouver Island’s Cowichan Valley, Cowichan Lake attracts anglers, kayakers and cottagers; visitors come for boating, fishing, shoreline trails and nearby provincial parks.
Cowichan Lake is a large freshwater lake on Vancouver Island in British Columbia and functions as a regional center for outdoor recreation. The nearby town of Lake Cowichan sits at the lake’s southeastern end.
The lake is used for boating, fishing, kayaking, and shoreline recreation, with campgrounds and day-use areas scattered along its shores. Forested hills surround the lake and trails and provincial parks in the area provide hiking and picnic opportunities.
The Cowichan Valley has been home to the Cowichan First Nation for millennia, and the lake later became the focus of logging and settlement during Euro-Canadian development of the island. The town and recreational infrastructure developed around the lake’s outlet and river access.
Cowichan Lake lies inland on central-southern Vancouver Island, with the town of Lake Cowichan at its southeast end and the Cowichan River draining the lake toward the island’s east coast.
- Access and services: The town of Lake Cowichan at the lake's southeast end provides the main access points, boat launches, and visitor services for recreation on the lake.
