Cham Island: Underwater Walking & Snorkeling Tour

Fish-eye view without the scuba hassle. Cham Island’s underwater walking lets you get up close with coral and fish using a helmet that provides oxygen while you stroll the sea floor. I like the mix of snorkeling plus underwater walking in one full day, and I also love that non-swimmers and non-divers can join with the right guidance.

Your day is built around hands-on moments, like hand feeding fish on the ocean floor and seeing animals you normally only spot from a boat. The staff also keep things organized, including safety support during the underwater walk, and guides may be friendly and confident, with names like Jimmy and Ho showing up in the experience reports.

One drawback to consider: you may not see the exact level of fish or coral color shown in marketing photos. Conditions like cloudiness and reef health can affect what you spot, so go for the experience, not a guarantee of rainbow visibility.

Key things that make this tour special

• Underwater walking with an oxygen helmet, so you do not need scuba gear or a diving license to participate
• Hand feeding fish from the sea floor, a rare moment where you are close enough to feel the interaction
• Split options for snorkeling versus underwater walking/diving, which helps you choose what feels comfortable
• Traditional boat ride to Cham Island, then time on the beach at Bai Chong Beach afterward
• Seafood lunch plus hammock time, so you balance active water time with proper downtime

Cham Island Underwater Walking, in plain terms

Cham Island is a popular Central Vietnam escape off the coast of Hoi An and Da Nang. This specific tour stacks three experiences into one day: snorkeling, underwater walking (often called sea walking or sea trek style), and beach time at Bai Chong Beach, plus a seafood lunch.

The biggest appeal is that underwater walking is not “regular snorkeling, but harder.” It is its own thing. You descend with a breathing setup that sits over your head and supports your buoyancy and breathing, then you walk along the seabed using handrails. It is designed so first-timers can do it without diving training.

Price check first: $68 per person for a 7 to 8 hour outing is usually a fair value for an activity that includes hotel pickup (when selected), a guide and safety instructor, snorkeling equipment, lunch, and mineral water. You are paying for more than a swim. You are paying for the staff time, the underwater gear, the guided safety process, and a full day structure.

Getting to Cua Dai Wharf and heading out

You start with a pickup from hotels in the center of Hoi An and Da Nang, if you choose that option. From there, you head to Cua Dai Wharf, where you board a boat.

On paper, the trip out is described as about a 1 hour ride to Cham Island on a traditional Vietnamese wooden boat. In real life, some days run faster. Either way, you should plan for a decent stretch of time on the water before you reach the island activities.

What matters for you: this is not a half-hour hop. You need to treat it like a full day. That also means your comfort prep counts. If you get seasick easily, you might want to consider that before you go. And if you hate sun exposure, plan for plenty of deck time while the boat cruises.

Snorkeling: the warm-up for what’s below

Once you arrive, snorkeling is part of the schedule. Even if underwater walking is your main reason for booking, snorkeling is still worth it because it helps you get your “water legs” before the helmet walk.

Expect a guided setup and snorkeling equipment provided by the tour. You can also end up in separate groups depending on what you choose. Some experience reports note that snorkeling and underwater walking happen with group rotations, with guides keeping an eye on participants.

What you are likely to see: coral habitat and lots of fish, plus animals such as anemones and starfish. Some guides take photos and videos, and there is often an option to purchase that later. If you wear prescription glasses, you may find underwater walking easier than trying to snorkel through with contacts, since the underwater walking uses a helmet.

Reality check: visibility can vary. Some people reported cloudier water and fewer fish than expected at one of the snorkeling stops. If you are the type who needs dramatic visibility to be happy, focus on the interaction and structure of the day, not only on the scenery.

Underwater walking: your oxygen helmet moment

This is the star of the show. Underwater walking is set up so you do not need diving experience. The key difference is that you walk on the sea floor while using a breathing helmet system that provides oxygen as you go down and up. You usually hold a railing while you move, and you descend and ascend under supervision.

From the experience details you can rely on:

• Non-divers and non-swimmers are welcome.
• You complete a health questionnaire before doing the underwater activity.
• Some participants split into two groups: snorkeling for some people, underwater walking for others.
• Safety support is close and continuous, including guides or divers staying in eyesight.

What you will do down there

You descend by ladder, then you follow the route along the seabed. The big “wow” moment is feeding fish by hand. You are often given bread to hold out, and fish swarm around you. It is strange and wonderful, like being in an aquarium but with real movement around you.

Coral is part of the experience too. Some people reported that coral may not look super bright, but it is alive and active. You might spot hard brain corals, crown of thorns starfish, and blue starfish, plus many fish varieties.

How it feels

It takes some courage the first time, mostly because you are trusting equipment and walking in open water. The tour is structured to reduce that fear by pairing you with a safety person, and by using an instructional video that covers how divers communicate and what to expect.

If you are nervous, focus on the basics: listen to the staff, keep your movements slow, and remember that you have support during the descent and while you walk.

Diving option, if you want it

This tour is designed so different skill comfort levels can fit into the day. While the underwater walking can be the main highlight for many people, there is also a diving option mentioned in how the groups are arranged.

You might find this helpful if:

• You want the underwater walk but someone in your group wants diving.
• You have mixed comfort levels and want the staff to handle the split.

If you choose diving, you should still treat this as an activity with medical screening. People with asthma, heart conditions, and respiratory issues may not be allowed to dive.

Bai Chong Beach and the seafood lunch reset

After your underwater activities, you head to Bai Chong Beach for lunch and downtime. Lunch is described as a delicious seafood meal, and you get time on the beach afterward. Some reports mention hammocks, so you can actually recover from the morning activities instead of rushing straight into another wave of swimming.

A few practical notes that matter:

• You might go from boat to sea and then to lunch without much time to change. Some people recommend going already in swimwear.
• Some participants noted that drinks are not included with lunch. If you want bottled water beyond the included mineral water, or if you want soda or beer, you should have a little cash on hand since alcoholic drinks can be purchased.

Beach chair and extra costs

Some reports mention deck chair hire at the beach. The tour includes lunch, but extra beach comfort can be an add-on.

Toilets and changing facilities were described as present and usable by participants, which helps if you are traveling with kids or you just want a clean reset after being in and out of the water.

What to bring (so you are not stuck improvising)

This tour includes snorkeling equipment, but you still need to show up prepared for the water parts and the beach parts.

Plan on bringing:

• Comfortable shoes
• A towel
• Comfortable clothes
• Swimwear, since changing time might be limited

Optional but smart add-ons based on real practical tips:

• Water shoes, especially for kids, since seabed walking can involve uncomfortable surfaces
• Your own snorkeling kit if you prefer familiar gear, and especially for small children
• Water for the day, since you can be out for 7 to 8 hours
• Basic first aid items like a disinfectant, waterproof bandages, and pain relief if you carry that kind of thing

Also pay attention to packaging rules. Some participants noted that plastic bags are not allowed on the island, so if you carry a bag, use something that can handle wet conditions.

Safety rules you should take seriously

This is not a casual stroll. Underwater walking is safe when you follow instructions, but it is still controlled risk with a medical screening step.

Before you go in:

• You will complete a health questionnaire.
• You should assume some conditions can prevent you from diving, including asthma and heart conditions, and the activity is not suitable for people with heart problems or respiratory issues.
• It is not recommended for pregnant women.
• Minimum age is 8 years.

On the water:

Staff are positioned so you are not “out there alone.” Some experience reports specifically mention a good ratio of safety support and a 1 to 1 diver during descent and ascent, with secondary breathing gear provided if needed.

If you are unsure whether your health profile will work, bring it up early. This is one tour where it is worth getting clarity before you arrive at the dock.

Who this tour fits best

This is a good fit if you want:

• A full-day activity that mixes snorkeling, underwater walking, and beach time
• An experience that welcomes beginners, since non-swimmers and non-divers can join
• A guided day that handles equipment and safety so you do not need technical planning

It can be especially satisfying if you have mixed skill levels in your group. Some participants did underwater walking while others snorkeled, with the staff rotating groups.

It might be less ideal if:

• You are expecting perfect reef visibility every time and will be disappointed by cloudy water
• You hate boats and long stretches on the water
• You have health conditions that make the activity unsafe or you fall into the not-suitable categories

Price and value: is $68 worth it?

For $68, you get a lot of built-in value because the day includes:

• Hotel pickup and drop-off in central Hoi An and Da Nang if that option is selected
• A professional guide and a safety instructor
• Snorkeling equipment
• Lunch, plus mineral water

You are also paying for the underwater walking infrastructure. That includes the helmet system and trained support for descent, ascent, and seabed walking. For many people, that is the “pay once, do it safely” portion of the day.

If you compare it to booking snorkeling gear and boat rental separately, you are paying less hassle and more organization. The only real “watch-outs” on value are the variable underwater conditions and the potential for extra purchases like photo or video packages and any drink or beach-chair costs.

My booking call: should you go?

I would book this tour if you want a hands-on underwater experience that does not require scuba training. The underwater walking setup, the fish feeding, and the structured safety support are the reasons it works for beginners and for families who want one shared highlight.

Hold off if you know you are sensitive to boat rides, or if your health profile could be an issue. Also, if your top priority is a guaranteed, super colorful reef photo look, understand that water cloudiness and reef condition can change the view.

If you are traveling from Hoi An or Da Nang and you want one day that feels like both adventure and a real break, Cham Island underwater walking and snorkeling is a strong pick.
