1. What Is Sea Walking And How Does It Work?

Sea walking, also known as helmet diving, is a specialized underwater activity in which participants wear an oxygen-supplied helmet that allows them to breathe normally while walking on the seabed. Designed to be beginner-friendly, this activity does not require any swimming ability, making it suitable for a wide range of individuals, including older adults and children aged 5 years and above.

After receiving a safety briefing, participants put on a life jacket and boarded a boat to the designated diving area. Upon arrival, trained staff assist each person in putting on the helmet before gradually descending to a depth of around 5 - 6 meters. Each sea walking session typically lasts from 20 to 30 minutes, offering ample time to observe marine life and coral up close in a calm, immersive environment.

2. Why Choose Phu Quoc for Sea Walking?

Phu Quoc Island offers ideal conditions for sea walking, thanks to its shallow waters, gentle currents, and excellent visibility. The marine ecosystem surrounding the island remains diverse and relatively undisturbed, featuring colorful coral gardens and a wide array of tropical fish.

In addition, most sea walking sites are located in the southern part of the island. One of the highlights is Namaste Coral Park, which is conveniently situated near the coast, ensuring safe and efficient transportation. Tour providers on the island are equipped with high-standard gear and staffed by professional guides, ensuring a smooth and secure experience for all visitors. These factors make Phu Quoc a leading destination for sea walking in Vietnam.

5. Tips And Considerations When Joining A Sea Walking Tour

Sea walking is an extraordinary but specialized activity that requires preparation and awareness. The following considerations will help ensure a safe, enjoyable, and environmentally responsible experience.

5.1. Health And Eligibility Considerations

This activity is generally suitable for most healthy individuals. However, those with cardiovascular conditions, high blood pressure, middle ear disorders, or respiratory illnesses are advised not to participate. It is also not recommended for young children under 5 years old or pregnant women. A health disclosure to the tour operator is essential before registration.

5.2. Pre-Tour Preparation

Participants do not need to know how to swim, but must closely follow all instructions from the guides. Avoid bringing jewelry or valuable items, as they can be easily lost or damaged. Wearing swimwear is advisable for ease of movement. Trimming fingernails and toenails beforehand can also help prevent accidental injury to yourself or delicate marine life.

5.3. Underwater Behavior

Underwater, it is crucial to respect the marine ecosystem. Avoid touching or stepping on corals to prevent damage. Walk slowly and maintain a balanced posture. It is normal to feel slight pressure in your ears; relax and breathe evenly. Keep your head upright to reduce strain caused by the weight of the helmet.
