Definition & Meaning of "snorkel diving"

What is "snorkel diving"?

Snorkel diving is an activity where a person swims near the surface of the water while using a snorkel, a mask, and sometimes fins to observe underwater life. Unlike scuba diving, it does not require an air tank, as the snorkel allows breathing while floating face down. Some snorkel divers take deep breaths and dive briefly to get a closer look at marine life before resurfacing. It is commonly done in shallow waters, such as coral reefs or coastal areas, making it an accessible and relaxing way to explore the underwater world.
