Welcome to Lake Cowichan, a stunning lakeside town nestled in a beautiful mountain valley. You'll find some of the highest summer temperatures in Canada here, making the crystal-clear waters of the lake and the gentle currents of the Cowichan River absolutely irresistible. A must-do is grabbing a tube and floating down the river; it's a relaxing journey of about two and a half to three hours that locals love on a hot day.
