Snorkelling is a process of swimming on or through water, equipped with a diving mask, called a special breathing tube, which usually includes swimming fins. You may also wear a diving suit in cool water. With this device, the snorkeler can observe underwater attractions for a long time with relatively small force and breathe when facing down.

Snorkeling is a popular recreational activity, especially in tropical resorts. The main attraction is the opportunity to observe underwater life in the natural environment without the need for complex scuba diving equipment and training. It's effortless and has no bubbles from diving equipment, so it's attractive to people of all ages. It is the foundation of two surface disciplines of underwater fin swimming.

Snorkeling can also be used when divers are on the surface of the water, in underwater sports (such as underwater hockey and underwater rugby), and in search and rescue teams' underwater searches.

Aristotle mentioned snorkeling in his animal part. He refers to divers using "breathing tools" similar to elephant trunks. There is some evidence that the snorkeling may have originated in Crete about 5000 years ago, when sea sponge farmers submerged and recovered natural sponges for trade and commerce using dug reed.

Snorkelers usually wear the same mask as divers. By creating airspace, the mask allows the snorkeler to see clearly underwater. All scuba masks consist of lenses (also known as faceplates), soft rubber skirts (which enclose and seal the nose on the face) and headbands that hold it in place. There are different styles and shapes. These ranges from elliptical models to lower volume masks, which can be made of different materials. Common choices are silicone and rubber. Snorkelers on the surface can use goggles that do not surround their noses.
