How to Dive

Diving involves the physical condition of the diver, various types of equipment, professional diving skills, and water visibility and temperature. Here are some skills to dive longer and deeper in safety:

• Technical diving: diving deeper than 40 meters (130 feet) using mixed gases, or entering overhead environments (caves or wrecks)
• Surface supplied diving: use of an umbilical gas supply and diving helmet
• Saturation diving: long-term use of underwater habitats under pressure and a gradual release of pressure over several days in a decompression chamber at the end of a dive

Having a picnic surrounded by the stunning natural scenery is also a great choice.

By diving in deep water, you will explore the wonderful underwater world. Thousands of splendid corals and fish, such as the sergeant major fish and Clark's anemone fish, will surprise you. You can see and even touch them; it's an unforgettable experience.

Safety Tips

• Choose a good time: during summer.
• Do a few exercises to warm-up before swimming or diving.
• All facilities are regularly checked and match safety standards, such as masks, fins, snorkels, cylinders, wet suits, and life vests.
• Be aware of jellyfish. First aid steps should be taken when you are stung by a jellyfish.
• Don't overestimate your swimming ability. Remember your swimming ability is severely decreased in cold water.
• Don't swim or dive while intoxicated.
• Don't dive into shallow water, or water of unknown depths.
• Don't swim for too long when it's very sunny as you can easily get sunstroke.
• Don't swim or dive alone.
• Don't go near the propeller of the cruise ship.
• Follow instructions about where and when to swim or dive.
• Children and elderly people should wear life vests or swim rings. There should be a lifeguard standing by.
• Special note: according to newly-published local laws, kayaking is no longer allowed in Halong Bay in order to protect the ocean and caves.
