Snorkel Trip to Koh Nangyuan and Bays of Koh Tao By The Oxygen
Koh Tao packs a lot into one boat day. This $29.70 snorkeling trip takes you from Mae Haad to Koh Nangyuan and several of Koh Tao’s best-known bays, with masks, snorkels, life jackets, lunch, drinks, and resort transfers included. I like the variety, especially the chance to see coral, schooling fish, turtles, and possibly reef sharks without arranging separate transport.
I also like the practical setup: the large boat has a toilet, GPS, a roof terrace, and space to rest between swims. The main drawback is size. With room for up to 120 people, this can feel more like a busy group outing than a quiet encounter with the sea. Weather controls the route, and the national park fee costs extra.

Key points to know before booking
- Koh Nangyuan is the visual highlight: Walk across its sand bridge, climb to the viewpoint, and snorkel at Japanese Garden.
- Four additional bays add variety: Mango Bay, Hin Wong Bay, Aow Leuk, and Shark Bay each offer a different underwater setting.
- The price covers the useful basics: Gear, transfers, a Thai lunch box, water, tea, coffee, insurance, and life jackets are included.
- Shark Bay brings the best wildlife possibility: Green turtles are possible, and blacktip reef sharks may appear on a lucky day.
- This is a large boat trip: The maximum group size is 120, so expect a social, organized outing rather than a private cruise.
- Check the departure time carefully: Pickup and sailing may be scheduled in either a morning or midday pattern.
What the $29.70 price really covers

At $29.70 per person, this is inexpensive for a six to seven hour boat excursion. The value comes from the bundle. You are not only paying for a ride to one island, but for several snorkeling stops, use of a mask and snorkel, a life jacket, lunch, drinking water, hot drinks, insurance, and two-way transfer from your Koh Tao accommodation.
The Thai lunch box matters more than it may sound. A day in the water works up an appetite, and the meal keeps you from needing to buy lunch separately. The food is described as basic but filling, and one particularly positive assessment found it better than expected for this kind of outing.
Water is available without an extra charge, and tea, coffee, and biscuits are served during the day. Soft drinks and beer are available for purchase at an additional cost. One practical detail puts the pricing in perspective: the national park admission fee is not included. You should budget 250 THB per adult or 150 THB per child, paid at the entry point.
The low price also comes with a tradeoff. This is a high-capacity boat, not a small charter. If you value ease, variety, and a low total cost, the arrangement makes sense. If you want silence, personal attention, or plenty of space around the boat, the group size may test your patience.

Starting at Mae Haad Pier on Koh Tao

Pickup is offered from your Koh Tao accommodation, usually during a 9:00 to 9:30 or 11:00 to 11:30 window. The boat then leaves Mae Haad Pier for Koh Nangyuan at either 10:00 or 12:00, with the full outing lasting about seven hours.
Those two timetable patterns deserve attention. The supplied schedule gives both morning and midday departure times, so you should confirm which one applies to your booking. A later departure could affect your other plans, especially if you have a ferry, diving course, or evening transfer to catch.
The listed starting point is Oxygen Tour Koh Tao at 8, 38, Koh Tao, Surat Thani 84360. The activity finishes back at the meeting point. Transfers are included from resorts, except for Mango Bay and Lighthouse Beach, which may require separate arrangements.
Once aboard, the large boat provides a useful base for the day. You have a toilet, a roof terrace, GPS, and a sounder. The roof terrace gives you somewhere to sit when you need a break from salt water and sun, though a large boat can still feel crowded when everyone moves around at once.
Koh Nangyuan: sand bridge, viewpoint, and Japanese Garden

Koh Nangyuan is the main event, and the schedule gives you about an hour there. Three small islands are joined by a narrow sand bridge, creating one of the most recognizable views around Koh Tao. You can walk across the bridge, go up to the viewpoint, or spend time in the water at Japanese Garden.
The sand bridge is worth seeing even if snorkeling is your main goal. It gives you a change of pace after the boat ride and lets you appreciate how the three landforms connect. The viewpoint adds another reason to bring a phone or camera, although access involves walking uphill.
Japanese Garden is the key snorkeling area at Koh Nangyuan. The water is described as clear, with colorful coral and tropical fish. Conditions vary with weather, tide, and the number of people in the water, so keep your expectations sensible. The site is famous, which means it may be one of the busier parts of the day.
You will need to pay the national park fee at entry. That charge is separate from the tour price, and it is worth carrying the required amount in Thai baht. The island stop combines scenery and snorkeling better than any other part of the schedule, so I would not treat it as a quick photo stop.
Mango Bay and Ao Muang for coral and fish
After returning to the boat, lunch is served before the group continues to Ao Muang, also called Mango Bay in the schedule. You get about an hour at this snorkeling point.
The attraction here is underwater variety, with coral and fish highlighted as the main sights. This stop is useful because it gives you a full hour in the water rather than a rushed swim. If you are new to snorkeling, that extra time lets you settle your breathing, adjust your mask, and get comfortable using fins if they are provided as part of the equipment arrangement.
Mango Bay is also one of the locations where transfer arrangements are different. The tour includes accommodation transfers except for Mango Bay and Lighthouse Beach, so do not assume the boat will collect you from that area.
A possible weakness is that the itinerary names both Mango Bay and Ao Muang, which may cause confusion when you are checking your schedule. They are presented together in the stop description, so confirm how your guide defines that part of the route.

Hin Wong Bay and the wall of yellow-striped fish

The next stop is Hin Wong Bay, with about an hour for snorkeling. The special sight here is a large gathering of yellow-striped scad fish. That kind of schooling fish display can be more impressive than spotting one large animal because the whole scene moves together around you.
Hin Wong adds a different feel from Koh Nangyuan’s Japanese Garden. Instead of combining a famous beach view with a reef stop, this part of the day focuses more directly on the fish. Your guide is expected to explain the snorkeling procedure and basic environmental rules, including the important instruction not to stand on coral.
That rule deserves attention. Coral is easily damaged by fins, feet, and careless contact, and the guide’s willingness to reinforce it is a good sign for the quality of the experience. You should stay horizontal in the water, keep your hands off the reef, and use the life jacket if you are not a confident swimmer.
The hour-long stop sounds generous, but remember that the actual swimming time includes entering the water, finding a comfortable area, and getting back aboard. Follow the guide’s return instructions closely.
Aow Leuk for large coral formations

Aow Leuk gives you about 40 minutes, making it the shortest snorkeling stop on the schedule. Its main appeal is large coral and attractive fish.
The shorter visit may be enough if conditions are good and you want to see several locations in one day. It also keeps the boat moving, so you are not tied to one bay for too long. I see this stop as a useful sample rather than a place where you will have time to explore every corner.
The quality of the experience depends heavily on visibility and sea conditions. The operator may adjust the five-stop route according to the weather, so the exact order or selection can change. That flexibility is sensible around Koh Tao, where wind and water conditions can affect snorkeling comfort.
Shark Bay and the chance of turtles

Shark Bay is the final snorkeling point, with about an hour in the water. The name may sound dramatic, but the draw is the possibility of seeing green turtles and, on a lucky day, blacktip reef sharks.
Wildlife sightings are never guaranteed. The right way to approach this stop is to value the reef and fish even if no turtle or shark appears. Several people have had memorable turtle sightings here, including one young swimmer who was able to fulfill a dream of seeing one in the water.
If you do encounter a turtle, give it space. Do not chase it, touch it, or block its route to the surface. The same calm approach applies to any shark sighting. Blacktip reef sharks are a possible sight, not a promised feature of every departure.
Shark Bay provides a strong finish because it adds a wildlife element after a day of coral gardens and schooling fish. It is also the stop where patience pays off. Spend less time scanning for a headline animal and more time watching the water around you.
A boat built for long hours on the water

The equipment package removes much of the usual hassle. Masks and snorkels are supplied, and life jackets are available for every person aboard. Insurance and an English-speaking guide trained for the activity are also included.
The guide support seems especially useful for mixed-age groups. The trip tends to attract plenty of people in their 20s, but the crew works to help different ages take part. That makes the outing suitable for families and mixed groups, provided everyone is comfortable with boat travel and swimming.
Some reviews praise the staff for being friendly, organized, and clear in their explanations. One specific strength is the attention to reef care. Another is the crew’s willingness to help people participate instead of leaving less confident swimmers on their own.
The boat may also have a slide, which adds a playful touch for children and adults. Some departures include free GoPro photographs, according to feedback from the experience, but I would not treat that as a guaranteed service unless the operator confirms it for your date.
You should bring swimwear, sun protection, and a towel, although those items are not listed among the inclusions. Since the roof terrace offers a place to relax, a dry layer can make the return journey more comfortable. These are practical suggestions, not supplied equipment.
Timing, weather, and the group-size tradeoff

The excursion lasts roughly six to seven hours and includes about five snorkeling areas. That is a lot of water time for the money, but it also makes for a full day. You will be moving between locations, boarding and leaving the boat, eating lunch, and sharing popular bays with other people.
The maximum capacity is 120. That figure is the most important consideration for anyone hoping for a quiet outing. Staff organization can keep a large group moving, but the water and boat deck may feel busy, especially at Koh Nangyuan.
The route depends on weather. If conditions are poor, the trip may be canceled or moved to another date, with a full refund offered if the alternative does not suit you. The same applies if the minimum of 10 people is not reached.
You can cancel for a full refund up to 24 hours before the scheduled start time. Cancellations or changes made inside that window are not refunded or accepted. The operator has also received one serious complaint about a same-day cancellation and delayed refund response, so keep your booking number and confirm any change directly with Oh-Hoo.
Who will enjoy this Koh Tao snorkeling trip?
I would choose this excursion if you want to see several parts of Koh Tao in one day and do not want to rent gear, arrange a boat, or plan lunch. It suits first-time snorkelers, families with children aged 4 to 10, and people who want a guided introduction to the island’s main bays.
It is also a good match for wildlife hopefuls. Shark Bay offers the chance of turtles and blacktip reef sharks, while Hin Wong focuses on large fish schools. Just remember that nature does not follow a timetable.
I would hesitate if you dislike large groups, need a private guide, or want long, unhurried time at one reef. Strong swimmers and experienced snorkelers may find the schedule pleasant but somewhat basic, especially at the 40-minute Aow Leuk stop.
People with pregnancy, high blood pressure, heart disease, or bone diseases are not recommended to join. Most other participants can take part, but you should be honest about your swimming comfort and use the supplied life jacket when needed.
Should you book it?
Book this tour if your priority is variety at a low price. The combination of Koh Nangyuan, four additional bays, equipment, lunch, drinks, transfers, and a full day on the water is hard to beat at $29.70, even after adding the national park fee.
Skip it if your ideal day means a small boat and empty beaches. For everyone else, this is a practical Koh Tao introduction with friendly staff, good organization, and real chances to see coral, fish, turtles, and perhaps a reef shark. Confirm your departure time, ask about the GoPro photos if they matter to you, and accept that the best wildlife sightings are lucky extras rather than promises.
