9 Safety Tips for Swimming in Halong Bay

Safey Tips

Swimming in Halong Bay is a unique experience that must not be missed. Imagine cooling off in the clear green waters of Halong Bay, surrounded by colossal limestone karsts, white sand beaches and lush jungle forests. The water is clean, calm and refreshing and you would have to be crazy to cruise around Halong Bay all day without wanting to take a dip.

To ensure the safety of those who swim in Halong Bay, it is important to follow these few safety rules:

• Don’t go swimming alone, if possible. It’s better to swim in groups as there will be people around to help if something goes wrong.
• Do not swim where there are known to be strong currents.
• Know your own ability - don’t swim in deep water, or far from the shore, if you have a low fitness level and cannot tread water for very long.
• If you get caught in large waves, the best course of action is to dive down as deep as possible as each wave comes. Then once there is a break in the waves, swim to shore.
• Don’t swim after drinking alcohol! The effects of alcohol slow down your reactions and could lead to accidents.
• Interestingly, there is research to suggest that human swimming ability is impaired in cold water, so if possible you should avoid swimming late at night and in the early morning when the water is colder than during the day.
• Children swimming in the water should be monitored by their parents at all times.
