Trip 3 : 3 Islands by boat
Phu Quoc’s An Thoi archipelago is at its best from the water, and this $29 full-day boat trip gives you three island stops without the cost of a private charter. You get beach time at Mong Tay, coral snorkeling near Gam Ghi, a stop at May Rut, and lunch served by the crew.
I like the simple all-in-one value and the friendly guiding, especially when guide Huy is leading the day. I also like that snorkeling equipment and lunch are included, so you can leave the hotel without arranging extra gear. The main caution is crowding: the boat and buses may feel packed, and Mong Tay’s swimming rules appear to have changed.
Key points to know before you book

- Three An Thoi islands in one day: Mong Tay, Gam Ghi, and May Rut each offer a different mix of swimming, snorkeling, beach time, and photos.
- Snorkeling is included: Gear is supplied, with the main reef activity taking place around Gam Ghi and another island stop.
- Mong Tay may have new restrictions: Swimming and snorkeling there have reportedly been stopped because of environmental pressure, so check the current plan.
- Lunch is served on the boat: The Vietnamese meal is widely praised, but tell the operator about dietary needs before departure.
- Large groups are possible: The listed maximum is 120 people, which can affect transfers, boarding, and time in the water.
- Weather matters: Poor sea conditions can cancel the trip, with a new date or full refund offered.
A practical day among Phu Quoc’s southern islands
This tour is built for ease. You meet at 143 Đường Trần Hưng Đạo in Dương Tơ, or arrange the offered pickup, then spend roughly eight hours moving through the An Thoi archipelago by boat. The route is not a private-island fantasy. It is a popular shared excursion, with the low price reflecting the number of people and the shared transport.
That tradeoff can work well. You get a full day on the water for $29, snorkeling gear, lunch, and several chances to swim or sit on a beach. You also avoid the work of finding a boat, negotiating a route, and arranging equipment yourself.
The day can be less smooth when communication is poor. Pickup times have caused problems for some customers, including delayed contact and confusion about collection. I would confirm your pickup location and time directly before the morning of the trip, even if your booking already shows those details.
The group limit of 120 is important. A boat of that size can feel lively and social, but it will not provide a quiet island escape. Boarding, moving from the boat to shore, and collecting snorkeling equipment may take patience.

Mong Tay Island, beautiful but worth checking first

The first stop is Mong Tay Island, also called Fingernail Island. The planned hour here is for relaxing, swimming, and enjoying the beach. It is the kind of opening stop that lets you settle into the warm water and get used to the pace of the day.
There is a practical wrinkle. A recent account says that swimming and snorkeling at Mong Tay had been banned because heavy visitor numbers and speedboats were putting pressure on the area. That means the advertised activity and the current experience may not match perfectly.
Before booking, ask the operator whether Mong Tay currently allows swimming. If not, expect a beach stop, photos, and time around the island rather than a full water session. The route may still include three islands, but the first stop could be more about scenery than snorkeling.
This is also where the shared-tour format becomes clear. If several boats arrive together, the beach can feel crowded. A small number of beach loungers may be available for an extra fee, and one account noted that few loungers were used despite the charge. If you prefer a towel on the sand, bring one and do not assume a lounger is included.
Gam Ghi Island is the main reef stop

Gam Ghi is the clearest reason to bring your swimsuit. The tour takes you to a coral reef area where you can use the supplied mask and snorkel to look for tropical fish. The scheduled stop lasts about an hour, so you have enough time to get in the water, but not enough for a long, slow reef session.
The quality of the snorkeling can vary with sea conditions, visibility, and the exact site used that day. Some accounts describe colorful fish and enjoyable reef time. Others found the underwater scene less varied than expected. That is a fair warning: this is an accessible island boat outing, not a specialist marine expedition.
I would treat Gam Ghi as a pleasant chance to see reef life rather than a guaranteed showcase of rare species. The coral was described as being in fairly good shape in places, but environmental pressure is a real concern. Large numbers of boats and swimmers can affect shallow reefs, so follow the crew’s instructions and avoid standing on coral.
The hour passes quickly. Put on your equipment as soon as the crew gives the signal, and keep track of your mask. One person had to retrieve a mask from the water after dropping it, with a replacement charge mentioned as $40. That is a good reason to handle the equipment carefully and keep a firm grip when boarding or moving around the boat.
Lunch on board adds real value

A Vietnamese lunch is served by the crew during the day, reportedly on board. This is one of the strongest parts of the package because it saves you from buying a separate meal during an island route where choices may be limited.
The food has received warm praise, with descriptions of a tasty meal and generous portions. It is not a restaurant stop, so keep your expectations sensible. You are eating as part of a moving group excursion, not sitting down for a long local food experience.
Dietary needs require advance attention. One serious complaint involved a vegetarian child who was unable to eat with the group, and the family said staff would not serve the meal as expected. The details of that incident are troubling enough that I would contact the operator before departure if anyone in your party is vegetarian or has food allergies.
Do not wait until lunch to explain your needs. Ask what vegetarian food can be provided and request written confirmation if the meal matters to your booking. The tour information confirms lunch, but it does not provide a full menu or guarantee for special diets.

May Rut offers the best relaxed finish
May Rut Island is the final scheduled stop, with about an hour for swimming, sunbathing, beach time, and photographs. This is likely to feel more open-ended than Gam Ghi. You can get back in the water, stay on shore, or simply enjoy a slower final stop before returning to Phu Quoc.
May Rut has been praised for its photo opportunities, and that makes sense for the final island. After a morning of transfers and snorkeling, a scenic beach stop gives you time to dry off and enjoy the setting without needing to rush into another activity.
The drawback is commercialization and crowding. One account described the third island as too busy and commercial, while another found it spectacular. Both reactions can be true on the same day. The island may look beautiful, but several boats arriving at once can change the mood quickly.
If you want photographs, use the first part of the stop before the beach fills up. If you want a lounger, ask about the price before taking one, since seating may not be included in the tour cost. You can still have a pleasant hour with a towel and a little patience.
The guide can make or break the day

The most positive comments focus on the crew and guide. The guide is expected to manage a complicated day involving hotel transfers, bus changes, boat boarding, meals, equipment, and several timed stops. When that coordination works, the experience feels easy.
Guide Huy is specifically praised for being attentive, watchful, humorous, and a strong host. Another guide was described as speaking very good English and keeping pickup on time. Those details matter because the tour has many moving parts. A good guide can explain where to meet, when to return to the boat, and how to use the snorkeling equipment without making you feel hurried.
The service is not always consistent. Some bookings have involved unclear messages, unanswered emails, or confusion over pickup. A coordinator named Rosie was mentioned in connection with deleted WhatsApp messages and a near-missed bus pickup. I would not rely on a last-minute message alone.
Save the operator’s contact details, confirm your hotel or meeting point, and arrive early. The official meeting point is 143 Đường Trần Hưng Đạo, Dương Tơ, Phu Quoc, and the activity ends back at the meeting point. If you use a pickup, make sure the operator has your correct phone number and hotel details.
Is $29 good value?

For a shared eight-hour excursion, $29 is a strong price. The fare covers the boat route, three island visits, snorkeling equipment, lunch, and, where available, pickup. A private boat would cost much more, and arranging each part separately would take time.
The price is best for someone who values convenience over privacy. You are paying for access to the islands and a ready-made day, not a quiet boat with flexible timing. The group can reach 120 people, so the low fare comes with less personal space and less control over how long you stay at each location.
Extra charges can affect the final cost. Beach loungers may not be included, and a lost or damaged mask could lead to a replacement fee. Ask about any optional seating before using it, and keep the supplied gear secure.
The meal is another reason the price works. Even if the lunch is basic, having it included means you do not need to carry a separate food budget for the middle of the day. For families and first-time visitors who want to see the southern islands without planning every detail, that is useful.
Weather and sea conditions are not minor details

This excursion depends on the sea. Authorities have canceled trips because of poor conditions, and the operator may also cancel if the minimum number of participants is not met. When that happens, you should be offered a different date or a full refund.
A canceled boat day can disrupt your plans, so avoid placing this tour on the final day of your stay if possible. Give yourself room to move it to another date. The free cancellation policy allows a full refund when you cancel at least 24 hours before the start time, but changes or cancellations inside that window are not accepted.
Sea conditions also affect snorkeling quality. Calm water can make the reef easier to see, while wind or rough water may reduce visibility or change the route. The exact order of stops may also shift as the crew responds to conditions.
Who will enjoy this boat trip most?
I would recommend it to you if you want a straightforward introduction to Phu Quoc’s southern islands. It suits couples, families, and mixed-age groups because you can choose between swimming, snorkeling, sitting on the beach, and taking photographs.
It also suits anyone watching their budget. The included lunch and equipment make the day easy to price, and the $29 fare is hard to beat for a full shared outing.
You may want a different experience if you dislike crowds, need a quiet boat, or want advanced snorkeling. The maximum group size is large, and the reef time is brief. You should also be cautious if you need guaranteed vegetarian or allergy-friendly food until the operator confirms the arrangements.
Environmental concerns deserve attention too. The reported restrictions at Mong Tay suggest that the islands are under pressure from heavy use. Enjoy the reef without touching coral, follow local rules, and accept that a stop may be shortened or changed to protect the area.
Should you book the three-island tour?
Book it if your priority is good-value island access with lunch and equipment included. The route gives you three different settings in one day, and a warm, capable guide can make the schedule feel surprisingly relaxed. Gam Ghi provides the main snorkeling opportunity, while May Rut is a good place to finish with photos and beach time.
Skip it if you want privacy, quiet beaches, or a carefully tailored food plan. Confirm the current Mong Tay restrictions before paying, and make sure pickup details are settled in advance. For a first look at the An Thoi islands, this is a useful budget choice, provided you accept the crowds and keep your expectations realistic.
