Canoeing is a popular recreational activity that involves paddling a canoe in either a river or LAKE. RAPIDS, which are fast-moving sections of a river, are often encountered when canoeing and can be dangerous if not navigated properly. Lakes are also a popular destination for canoeing, as they provide a calm and peaceful environment for the activity. LAKE canoeing is generally considered to be less dangerous than canoeing in RAPIDS, as the waters are usually calmer and more predictable.
