Snorkeling (British spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask, a shaped tube called a snorkel, and usually swimfins. In cooler waters, a wetsuit may also be worn. Using this equipment allows the snorkeler to observe underwater attractions for extended periods of time with relatively little effort.
It is a popular recreational activity, particularly at tropical resort and scuba diving locations. Snorkelling is also employed by scuba divers when on the surface, and search and rescue teams may snorkel as part of a water-based search.
The primary attraction of snorkeling is the opportunity to observe underwater life in a natural setting without the complicated equipment and training required for scuba diving, in addition to the exhaled bubbles of scuba-diving equipment. Snorkeling is also a means to an end in popular sports such as underwater hockey, underwater ice hockey, underwater rugby and spearfishing.
