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. Using this equipment allows the snorkeler to observe underwater attractions for extended periods of time with relatively little effort.
Snorkeling is a popular recreational activity, particularly at tropical resort and scuba diving locations. The primary attraction is the opportunity to observe underwater life in a natural setting without the complicated equipment and raining required for scuba diving, and without the exhaled bubbles of scuba diving equipment.
