Snorkelling

A mask and snorkel can give many visitors their first close look at the reefs around the An Thoi islets, but water clarity, current and boat traffic change from day to day. Listen to the safety briefing before entering the water and judge the experience by the actual sea, not by promotional photographs.

How to schedule?

If you are new to snorkelling or not a confident swimmer, tell the guide immediately so you can be fitted with a suitable life jacket and given closer support. Ask how much actual water time is included, how to use the equipment and what signals to use if you need help. Return to the boat if you become tired, cold or short of breath.

Easy to try does not mean safety can be ignored
Weak swimmers can still snorkel in suitable conditions with a life jacket and proper support, but nobody should be pressured into the water if they are frightened or conditions are poor.
Beginners should practise breathing in shallow water or close to the boat before moving further away. Young children need direct adult supervision rather than being left entirely to a guide in a crowded sea area.

What may be different

Coral is living habitat, not a rock platform for standing or resting. Water can also be less clear and fish less visible than in advertising on any particular day. A good snorkelling trip means seeing the marine environment without damaging it by touching, standing on or breaking coral.

Snorkelling quality changes from day to day
Visibility, current and boat density directly affect the experience. Do not judge a site only from photographs taken in ideal conditions.
If the sea is unsuitable, shortening the session or moving to another site is safer than forcing the original plan simply to complete the advertised activity list.

Before the trip

Listen to the full briefing and wear a life jacket whenever your ability or the conditions call for one.
Do not touch or stand on coral, and do not feed fish.
Stay within the supervised area and do not swim away from the group.
Signal for help and return to the boat if you feel tired, cold, tight-chested or short of breath.
