snorkelling

Snorkelling is a form of recreational swimming that allows observers to view underwater life at the surface while lying face down in the water. It typically uses a mask to see clearly, a snorkel to breathe air from above, and fins for propulsion. While commonly associated with tropical reefs, snorkelling can be practiced in oceans, seas, lakes, and rivers, provided conditions are safe and visibility is good.

Core equipment consists of a mask, a snorkel, and fins. The mask creates an air space in front of the eyes and nose for clear vision underwater. The snorkel provides a tube for breathing air while the face is submerged. Fins enhance swimming efficiency and stability. Optional items include a wetsuit or rash guard for temperature and protection, weight belts for deeper dives, and a camera or underwater light for documentation.

Most snorkellers lie face down and glide with slow, steady kicks from the hips using fins. Breathing is done through the snorkel, keeping the head low and the body horizontal. Water inside the snorkel can be cleared by blowing bubbles or exhaling forcefully through the mouth. If water enters the mask, tilt the head and push the mask away from the face to drain, then reseal.

Snorkelling is generally accessible but carries risks. Never snorkel alone; use a buddy system and stay within depth and area limits. Be aware of currents, waves, boat traffic, and changes in weather. Avoid contact with marine life and fragile habitats, and do not touch coral or seagrass. Use reef-safe sunscreen and stay hydrated; if snorkelling from a boat, wear a life jacket and follow local safety guidelines.

Snorkellers should minimize impact by not standing on coral, not removing organisms, and avoiding litter. Respecting local regulations helps protect ecosystems and ensures sustainable enjoyment for others.
