Many customers visiting Phu Quoc have messaged us with the same concern: “I really want to see the coral, but… I’m afraid of water and can’t swim. Is there any way?”. Many women even hesitate to use traditional snorkels because they worry about choking on seawater, jaw fatigue, or washing away the makeup they carefully applied since morning.
If you share these same struggles, we promise this article will completely solve your problem. Here, we will break down exactly what sea walking is, how it works, provide a real review of the multi-sensory experience at the bottom of the South Island sea, and update you on the latest prices. Taking just 3 minutes to read, you will know exactly if this activity is truly worth the money for your upcoming trip.
The reality of diving in Phu Quoc: Not everyone likes snorkeling
During peak season, shallow coral reefs are often quite crowded. Snorkeling is cheap, but it requires you to know how to swim a little, be used to breathing through your mouth, and not be afraid of getting water on your face. In reality, over 40% of our island tour guests have choked on water or given up right after putting their faces in the sea because they felt overwhelmed by the waves. That is why Phu Quoc sea walking (Sea Walker) was created—to specifically serve customers who want a safe, relaxing, and more premium experience.
What is sea walking? How is it different from normal diving?
Put simply, the sea walking experience is like wearing an “astronaut helmet” and taking a walk on land, except you are surrounded by seawater and fish.
You will wear a specialized oxygen helmet that weighs about 30kg on land. But don’t panic! Thanks to Archimedes’ buoyant force, once underwater, this helmet only weighs around 4kg—just enough to keep you standing firmly on the seabed without causing any neck or shoulder pain.
- The biggest plus: You breathe completely normally through your nose and mouth just like on shore. Seawater is pushed out by the air pressure continuously pumped into the helmet. Your hair stays completely dry, prescription glasses won’t fog up, and your sunscreen or makeup remains 100% intact.
Can non-swimmers go sea walking?
This is the question we receive the most. The answer is: 100% yes.
Do you need to know how to swim for a Phu Quoc sea walking tour? Absolutely not. You don’t need to tread water or swim. Your only job is to walk slowly on the sandy strip at the bottom of the sea. Additionally, a strict safety rule requires a professional dive instructor to accompany you 1-on-1 throughout the entire journey. The instructor will hold your hand, guide you to interact with the fish, and handle any situation.
Is Phu Quoc sea walking safe for children and the elderly?
This tour is particularly suitable for families, but there are physical limits you must know to ensure absolute safety.
- Can children go sea walking? Kids from 5 years old and up, who have enough height and stamina to wear the oxygen helmet (fitting their head size), can participate.
- For the elderly: This activity is safe; however, we refuse to serve customers with a history of cardiovascular disease, high blood pressure, asthma, or pregnant women due to the changing underwater pressure environment.
Tips from locals: If your family has elderly members who don’t meet the conditions to go underwater, they can still sit, rest, drink water, and enjoy the view on the luxurious space of the Nautilus yacht while waiting for others to finish their experience.
Real experience: What is at the bottom of the South Island sea?
Instead of squeezing onto old, shaky wooden floating rafts, we choose the South Island Coral Conservation Park combined with the 5-star Nautilus Yacht as our landing spot.
What does it actually feel like? As soon as you step down the first stairs, you will feel the cool seawater wrapping around your body. Once fully submerged, the surrounding sound quiets down, leaving only the rhythmic bubbling of breathing air. You will be amazed by the light piercing through the crystal-clear water. Don’t be surprised when colorful schools of fish actively swim right up to your helmet glass, and you can gently touch the soft corals swaying with the current. At the conservation park, the density of marine life is thick with over 200 species of fish and coral, much more vibrant than free diving spots.
Minor drawback (Please note): When you first go down about 1-2 meters, your ears will pop (just like when an airplane takes off or lands). Don’t panic! The instructor will guide you to swallow continuously or use the “ear breathing” trick, and this feeling will disappear after a few seconds.
How much is a Phu Quoc sea walking tour? (Updated 2026)
The cost for this experience is higher than snorkeling, but it is completely worth it for the 5-star yacht service and equipment technology. Currently, the reference price list at Nautilus is as follows:
| Service Package Name | Price (USD/Guest) | Who is it for? |
| Experience Package | 43.8 USD | Only includes diving; you handle your own filming and photos. |
| Standard Package | 59 USD | Often chosen by guests to mix with their island-hopping itinerary. |
| Standard Combo | $70 USD | Recommended! Includes shuttle bus, speedboat to the yacht, and especially an underwater diver to film and take photos for you. (Trust us, taking your own phone underwater yields very blurry footage and high risk of damage; let the professionals handle this part). |

Preparation guide: To get photos of a lifetime
- Golden hour: 11:30 – 13:30. Don’t go too early or too late. The bright midday sun is when sunlight shines straight down onto the sea surface; the water is crystal clear, and the coral colors bloom the brightest. Your photos won’t turn out dark.
- What to wear: Wear a neat swimsuit underneath your clothes right from the hotel. Avoid bulky dresses underwater because of the high drag. The Nautilus yacht has extremely clean showering and changing areas, so you can rest assured.
- How to optimize costs: If you plan to go on a 3-island or 4-island tour, notify the tour operator in advance to graft the sea walking part into the itinerary. The speedboat will swing by the Nautilus yacht for you to dive first, before going island hopping. This method saves a lot of time and transfer speedboat costs.
