Southern Phu Quoc Sea Walking Experience at Roi Island

At Roi Island, you can stroll along the seabed in a 33kg helmet while fish pass close by and coral fills the view. No swimming skills are required, and an instructor accompanies you underwater, making this an accessible way to try an ocean activity without scuba training.

I like two things about this outing: the one-to-one diver support described for the underwater walk, and the short, manageable time below the surface. You also get boat transport and, depending on where you stay, hotel pickup and drop-off. The trade-off is that the walking area is small, and extra costs for photos, transfers from some areas, or add-on activities can change the total price.

At a glance

• A helmet walk, not a swim: You walk on the seabed for about 15 to 20 minutes with an air-fed helmet.
• Close-up marine life: Expect fish, coral, and a fish-feeding stop in the Ocean World Coral Park area.
• An instructor stays nearby: Each participant may be accompanied by a diver, with staff giving safety instructions before the walk.
• A half-day outing: The shared trip combines a road transfer, a boat ride, and time at Roi Island.
• Extras cost more: Photos, videos, glass-bottom boat rides, scuba, and some hotel transfers are not included in the base price.

What the Roi Island Sea Walk Is Really Like

Sea walking is a guided underwater activity for people who want to see marine life without learning scuba skills or swimming. You wear a helmet weighing about 33kg above water; once underwater, it supplies air so you can breathe while standing and walking on the seabed.

The walk lasts around 15 to 20 minutes. That is enough time to take in fish and coral at close range, but not enough to cover a large area. The experience is more about seeing marine life right in front of you than exploring a broad stretch of reef.

The advertised Ocean World Coral Park is described as having more than 200 species of coral and other marine life. Conditions can affect what you see, and the walk takes place in a limited area. One participant described the water as cloudy on their visit, while others found the underwater view clear. Think of this as a short, guided introduction to the seabed, not a guarantee of perfect visibility or a long reef excursion.

The Road to the Harbor and Boat Ride

The outing begins with a shared transfer, usually from a hotel in the Duong Dong area. The road trip to the harbor can take around 45 minutes, according to one account, and the boat ride to the activity area has been described as about 30 minutes. Your actual travel time may vary with traffic, weather, and the day’s arrangements.

The journey is part of the value: you do not have to arrange your own transport to the harbor or boat. It also means that the 15-minute underwater walk sits inside a much longer outing. Plan on roughly three hours from hotel pickup to return, though the schedule and timing can vary.

Pickup is offered from a number of areas, including Duong Dong, Bai Truong, Bai Khem, Bai Sao, and An Thoi town. Some other areas carry a cash surcharge: listed rates are VND 100,000 per person from Ong Lang and Cay Sao or Ham Ninh, VND 200,000 from Cua Can or Vung Bau, and VND 400,000 from Bai Dai or Ganh Dau. Confirm the cost for your hotel before you book.

If you are staying in Sunset Town or along the road to the cable car station, you cannot be picked up directly at your hotel because of local traffic restrictions. The stated meeting point is the entrance to Vui Fest Night Market. Arrive early, as late arrivals and no-shows are not refunded.

Getting Ready for the Helmet Walk

At Roi Island, staff provide the equipment and explain what to do. The activity includes an English- or Vietnamese-speaking guide, a boat trip, mineral water, the helmet walk, and a fish-feeding ticket. Participants have described the instructions as clear, and the presence of an accompanying diver can be reassuring if you feel nervous before going underwater.

The helmet is heavy on land, but the point is that you do not need to handle complicated scuba equipment. You descend with staff and then walk along the seabed while breathing through the helmet. You can keep your attention on the fish and coral rather than on swimming technique.

Allow for the possibility of ear pressure as you descend. One participant had trouble equalizing their ears, while their partner did not. If you know you have difficulty with pressure changes, consider whether this activity is right for you and ask the operator about it before you go. The activity is not recommended for people with certain medical conditions, including high blood pressure and epilepsy. Anyone who appears intoxicated may be refused service without a refund.

Bring swimwear, a towel, a change of clothes, sunscreen, sunglasses, a hat, and toiletries. You will want dry clothes for the return trip. The operator recommends considering accident or travel insurance, though it is not mandatory.

What You See Underwater

The walk is a compact encounter with fish, coral, and other marine life. You may see schools of fish close to the route, and fish feeding is included. Some participants have found it especially fun to feed fish by hand; keep to the staff’s instructions so the activity stays controlled and does not become a free-for-all.

The seabed route is not large, and the range of fish species may feel limited if you expect a broad reef safari. That is worth knowing before you pay. The appeal is proximity: you are standing underwater with fish near your face, rather than looking down from a boat or swimming over a reef.

The guide also introduces marine ecosystem protection and underwater organisms. This adds a useful note to an activity that could otherwise feel like a photo stop. Treat the coral and sea life with care, and follow staff directions throughout.

The Return and Optional Add-Ons

After the walk, you return by boat and then transfer back to your hotel or the agreed drop-off point. Departure choices are listed at 10:30 and 13:30, with return times that may be 14:00 or 17:00 depending on the selected schedule and the day’s arrangements. Weather and traffic can change the timing, so avoid planning a tight connection afterward.

You can pay extra for a glass-bottom boat ride or scuba activity at Roi Island. Neither is included in the standard sea-walking price. If you want a longer look at the water or a different way to explore it, these might be worth asking about, but confirm the cost before you commit.

Photography and video are also separate. Some people have been pleased with the paid images, while others have found the price high for the amount of material received. One quoted on-site price was VND 600,000 for photos and video, but packages and delivery may vary. Ask exactly what you will receive, how many images or how much video, and how it will be sent before paying. A waterproof phone case may not be useful at the activity depth, so check with the operator rather than buying one just for this outing.

Is the $65.15 Starting Price Good Value?

The standard join-in sea-walking package starts at US$65.15. It bundles the underwater activity and equipment with a guide, boat transport, a fish-feeding ticket, mineral water, and hotel transfers where available. If you would otherwise need to arrange a ride to the harbor and boat transport yourself, that combination has practical value.

It is less compelling if you are looking for a long underwater adventure. The sea walk lasts only about 15 to 20 minutes, and the area is limited. You are paying for a guided, unusual way to get close to fish without swimming or scuba skills, plus the transport and organization around it.

The alternative package with scuba starts at US$72.39, but the listed details for the sea-walking package do not make the scuba option’s inclusions clear. Check the package terms before choosing it. The base price also excludes meals and beverages, gratuities, personal expenses, photos, glass-bottom boat rides, scuba, and VAT. A holiday surcharge of VND 270,000 per person applies on the listed public holiday dates in 2027.

Who Will Enjoy This Outing Most

This is a good fit if you are curious about the underwater world but uneasy about snorkeling, cannot swim, or do not want to take a scuba course. It can also work for families with children, provided every child and infant is included in the passenger headcount and the operator confirms suitability for the child’s age and needs.

If you are already a confident snorkeler or scuba diver, you may find the short route and limited area less rewarding than a longer reef trip. Consider a snorkeling day tour or a dedicated scuba outing if your main goal is to cover more water or see a wider range of marine life.

The operation has received strong praise for kind staff, clear instructions, and attentive instructors. There have also been complaints about worn facilities, rusty lockers, waiting, and inconsistent photo service. The underwater support is the activity’s strongest practical point, but do not assume every part of the onshore setup will feel polished.

A Few Booking Details to Check

Hotel pickup is shared, so your vehicle may arrive early or late. Enter your hotel name and address when booking, then wait for the operator to confirm the pickup time. Be at the hotel lobby 10 minutes before the scheduled time, or arrive at the meeting point 10 to 15 minutes early.

You can change a booking up to 24 hours before the activity in many cases, but some booking types cannot be changed. A full refund is available for cancellations made at least 24 hours before the activity date. If extreme weather or another unforeseen event leads the operator to cancel, you may be able to reschedule or request a refund, subject to the operator’s approval.

Should You Book the Roi Island Sea Walk?

Book it if the idea of walking underwater sounds more appealing than swimming, and you value having a guide close by. The short duration makes it a manageable first taste of the seabed, while transport and the boat ride simplify the day.

Skip it if you expect an expansive reef, guaranteed clear water, or photos included in the price. Before booking, check your hotel’s transfer surcharge, confirm your departure time, and ask about the exact photo package if pictures matter to you. With those points settled, this is an unusual, approachable way to see fish and coral close up in southern Phu Quoc.
