Canoeing is an sport or recreational activity which involves paddling a canoe with a single-bladed paddle. Kayaking is the use of a kayak for moving across water. It is distinguished from canoeing by the sitting position of the paddler and the number of blades on the paddle. A kayak is a low-to-the-water, canoe-like boat in which the paddler sits facing forward, legs in front, using a double-bladed paddle to pull front-to-back on one side and then the other in rotation.
It is an activity that can be physically demanding given the variables of terrain and water.
