5 Islands Full-Day Tour Around Koh Tao and Koh Nangyuan

The best part of this seven-hour boat day is the variety. You move from Koh Nangyuan’s famous sandbar and viewpoint to coral-filled bays around Koh Tao, ending at Shark Bay, where turtles and blacktip reef sharks may appear. The tour keeps the day simple with gear, lunch, transfers, and underwater photos included.

I like the helpful guides, especially when they point out turtles and smaller sea life rather than leaving you to search alone. I also like the value: at $27.71 per person, you get several snorkel stops, food, drinks, equipment, and transport in one package. The main consideration is that this is a shared boat, with capacity up to 60 people, and the sea can be rough.

The 5 things to know before booking

• Koh Nangyuan takes center stage: You get time for the iconic beach, separate swimming areas, and the hilltop viewpoint.
• Shark Bay is the big wildlife chance: You may swim near turtles and blacktip reef sharks, but sightings are never guaranteed.
• Lunch is served on board: Thai food, drinking water, coffee, tea, and fresh fruit help keep the long day comfortable.
• The route changes with the weather: Mango Bay or another stop may be replaced when waves, wind, or currents make conditions poor.
• The boat can be fairly large: The maximum is 60 people, so this is not a private or intimate trip every day.
• Budget for Nangyuan’s entrance fee: Adults pay THB 250 and children pay THB 120, with the adult rate applying to children taller than 120 centimeters.

Why this Koh Tao snorkeling day offers good value

At $27.71, this is one of those excursions where the low price makes sense only because many services are bundled together. You are not paying just for a boat ride. The price includes pickup and return to most hotels, snorkeling equipment, life jackets, a Thai lunch box, drinks, fruit, a professional English-speaking guide, basic accident insurance, and underwater photos sent to you later.

I especially like the practical design. You do not need to hunt down a rental shop, pack a lunch, or arrange a taxi to Mae Haad Pier. After hotel pickup, you meet the Sangthong Tours crew at the pier, complete a quick health check, receive your equipment, and board the modified fishing cutter.

The trade-off is scale. The stated maximum is 60 people, and some departures can feel like a large group, even if the boat has room to move around. If you want a quiet boat, flexible timing, or a private guide, this is not the right product. If you want to see several parts of Koh Tao without paying private-tour prices, it is a strong deal.

The tour has a 4.6 rating from 69 reviews, with 91 percent recommending it. That fits the experience described by the details: the main strengths are the crew, the scenery, the food, and the chance to see turtles. The weaker points are organization on some days, large numbers on the boat, and weather-related changes.

Starting at Mae Haad Pier

Your day begins with hotel pickup and a drive to Mae Haad Pier. The listed meeting point is 3RMF+WP6 in Koh Tao, and the tour finishes back there. Pickup is included from most hotels, but the service does not cover Mango Bay or Lighthouse Beach, so check your accommodation before assuming a door-to-door transfer.

At the pier, the crew handles the practical setup. You receive snorkeling equipment and a life jacket, then board the boat after the health check. Coffee, tea, water, and fresh fruit are available, which is useful because a full day on the sea can feel longer than the advertised seven hours.

The boat is a modified fishing cutter rather than a sleek speedboat. That gives the trip a more local working-boat feel, though it can also mean a noisier, slower ride than you might expect from a high-speed excursion. Bring only what you need, keep valuables protected from spray, and listen carefully during the safety briefing.

Koh Nangyuan and its famous sandbar

Koh Nangyuan is usually the first major stop, off Koh Tao’s northwest coast. The island group is linked by a narrow beach, and this sandbar is the picture-postcard scene that attracts many visitors to the area.

You have about 90 minutes here. That is enough time to walk the beach, use one of the separate swimming areas, and climb to the viewpoint on the highest of the three connected islands. The view from above is one of the strongest parts of the day, especially when the sea is calm and the three small islands line up clearly below you.

The climb is worth planning for. Wear shoes or secure sandals for the walk up, and save some energy for the return to the beach. You will also want to keep your phone and camera protected from water during the swim.

Koh Nangyuan charges an additional entrance fee: THB 250 for adults and THB 120 for children. Children taller than 120 centimeters pay the adult rate. This cost is easy to overlook when comparing tour prices, so add it to your budget before booking.

Nangyuan can also be busy. The beach is compact, and the viewpoint is popular. Still, the combination of a short hike, clear water, and the distinctive sandbar makes this a worthwhile first stop.

Mango Bay and lunch on the boat

From Koh Nangyuan, the boat heads toward Mango Bay on Koh Tao. The bay takes its name from the mango trees that once grew there in large numbers. You have about an hour for the stop, with lunch served on board as you travel or anchor nearby.

The Thai-style lunch box is simple rather than luxurious, but it solves an important problem. You do not lose time searching for food, and you can refuel between snorkel sessions. Water, coffee, tea, and fresh fruit are also provided throughout the day.

Mango Bay is known for its clear water and marine life, but its condition depends heavily on the weather. On some days, the captain replaces it with another bay. That can be disappointing if you chose the tour for a specific location, but a weather-based change is sensible when wind or waves make the original stop less comfortable or safe.

This is also a good place to remember that advertised routes are not fixed promises. The operator says the program can change because of weather and sea conditions. I would book this trip for a full day around Koh Tao, not for one particular bay.

Hin Wong Bay and the east coast

The next stop is Hin Wong Bay, set on Koh Tao’s east coast among large boulders. The scenery changes here. Instead of the open beach and sandbar at Nangyuan, you get a more rugged shoreline and underwater pinnacles covered with coral and anemones.

You have about an hour to snorkel. The area can be rewarding for people who enjoy looking closely at coral formations and smaller fish. The underwater pinnacles give the stop more structure than a simple swim from a sandy beach.

Sea conditions matter here. The east coast can be exposed to wind and current, and one review specifically notes that rough seas made the day difficult for some people. Wear the life jacket if you are not a confident swimmer, and follow the guide’s instructions about where to enter and how far to swim.

The guides are one of the tour’s strongest features. They do more than point toward the water. They help you find fish and turtles, take underwater photos, and keep an eye on the group. Guides have also climbed the viewpoint with visitors to take photographs, which is a small but thoughtful touch.

Aow Leuk’s sheltered shape and white sand

Aow Leuk is the next snorkeling stop, with another hour in the water. Its name refers to the bay’s deep, curved shape and the depth of the water, which can make it suitable for snorkeling even at low tide.

The bay combines white sand, clear water, and a more traditional beach setting. If you need a break from looking down through your mask, this is a pleasant place to appreciate Koh Tao from the boat or shore.

The several one-hour water stops make the schedule active. You are repeatedly getting in, swimming, climbing out, drying off, and moving again. That is excellent for someone who wants a full day of snorkeling, but it can be tiring for anyone who prefers a slower pace.

I would use each stop differently. At one bay, focus on coral and fish. At another, spend more time swimming. You do not need to stay in the water for the entire hour every time.

Shark Bay and the chance to see turtles

The final major stop is Shark Bay, also called Thian Og Bay, where you have about 45 minutes before returning to the pier. The bay is known for blacktip reef sharks and sea turtles that visit the area.

This is the most exciting wildlife stop, but keep your expectations sensible. Some departures see several turtles, baby sharks, or a large turtle close by. Others see only one turtle, a few fish, and coral. Sea life moves freely, and no guide can promise a sighting.

The guides can improve your chances by taking you to the right part of the bay and pointing out animals beneath the surface. They may also take photos while you swim. Underwater images are provided free after the tour, which adds real value for anyone who does not have a waterproof camera.

Follow the safety instructions here. Blacktip reef sharks are not a guarantee of danger, but they are wild animals. Use the life jacket if you need it, keep a respectful distance from turtles, and avoid chasing marine life for a photograph.

What the boat day feels like in practice

The appeal of this trip is momentum. You see a famous island, several different bays, a viewpoint, and a final wildlife area in one day. It gives you a broad introduction to Koh Tao without requiring separate bookings.

The drawback is that the schedule can feel crowded. A maximum of 60 people is a lot for a snorkeling boat, and some departures have been described as carrying around 50 people. The operator notes that two boats may sometimes anchor at the same sites, with the number of people controlled at each location, but you should still expect a shared group outing rather than a private experience.

Organization can also vary. Most of the supplied feedback is strongly positive, but there have been complaints about a late pickup and confusion around arrangements. I would confirm your pickup details clearly and arrive ready at the hotel lobby. The tour team has acknowledged that punctuality needs attention.

Conditions make a bigger difference than almost anything else. Calm seas can produce the easy, aquarium-like snorkeling people hope for. Strong currents and large waves can make even a beautiful bay uncomfortable. The operator can cancel for poor weather and offer another date or a full refund, or it can change the route during the day.

Who should book this tour

I would choose this trip if you want an affordable first look at Koh Tao and prefer having transport, food, and equipment arranged for you. It suits couples, families with older children, and solo visitors who would rather join a group than organize boat transport on their own.

It is especially good for people who want more than one snorkeling location. Koh Nangyuan supplies the famous viewpoint and beach, while Hin Wong and Aow Leuk offer different coastal settings. Shark Bay adds the possibility of turtles and reef sharks.

You should think twice if you get seasick, dislike large groups, or want a quiet private boat. Rough water has made some departures uncomfortable, and a full day of repeated snorkeling stops can be demanding. You should also be comfortable with the extra THB 250 Nangyuan entrance fee and the chance that the route will change.

Free cancellation is available up to 24 hours before the start time. Changes made within 24 hours are not accepted, and late cancellations are not refunded. If poor weather or too few bookings causes the operator to cancel, you can receive a different date or a full refund.

Should you book the 5 Islands tour?

Book it if you want the most sightseeing and snorkeling you can fit into roughly seven hours for a low price. The guides, lunch, equipment, hotel transport, and underwater photos make the package unusually practical, while Nangyuan’s viewpoint and Shark Bay’s turtles give the day two memorable targets.

Skip it if you need a small boat or a guaranteed route. The group may be large, weather can replace Mango Bay or another stop, and wildlife sightings are never certain.

For most visitors staying on Koh Tao, I think this is a sensible value choice. Go on a day with good sea conditions, bring sun protection and secure footwear, budget for the Nangyuan fee, and treat the route as flexible. That is the best way to enjoy the scenery, the coral bays, and whatever marine life happens to appear.
