In summertime this river is the warmest for swimming or tubing. Traditionally April 30 is the date for my first dip and the water is still damn cold, but the dip is doable. For tubers the Cowichan River has enough rapids to keep things interesting and smooth waters for conversing or imbibing. Coming out of the water a cleansed feeling of body and mind is experienced. The Cowichan River is a great and scenic little river.
