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

Clear water, five stops, one busy day. This Koh Tao boat trip packs in Koh Nangyuan, Mango Bay, Hin Wong Bay, Aow Leuk, and Shark Bay, with lunch and snorkeling gear included. I like the low price and the fact that a guide helps you find marine life rather than leaving you to guess where to swim. I also like the free underwater photos, a useful souvenir when your hands are busy with a mask and fins. The main catch is that sea conditions can change the route, and the boat may hold many more than 15 people.

The day begins with hotel pickup and ends back at Mae Haad Pier, lasting about seven hours. You get drinking water, coffee, tea, fruit, a Thai lunch box, life jackets, basic accident insurance, and an English-speaking guide. You must still pay the Koh Nangyuan entrance fee, THB 250 for adults or THB 120 for children, and the ride can feel rough when wind and waves rise.

Key points to know before you book

• Koh Nangyuan costs extra: The adult entrance fee is THB 250, and children taller than 120 centimeters pay the adult rate.
• Shark Bay is the wildlife highlight: You might swim near blacktip reef sharks or sea turtles, but sightings are never guaranteed.
• Five stops fill the day: You visit Koh Nangyuan, Mango Bay, Hin Wong Bay, Aow Leuk, and Shark Bay, though weather can force a change.
• Lunch is served on board: Thai food, fruit, water, coffee, and tea are included, so you do not need to pack a full meal.
• The boat may be large: The stated maximum is 60 people, and one account describes around 50 people on board.
• Photos come free afterward: Guides take underwater pictures, including shots near turtles when conditions allow, and send them to you.

What a seven-hour Koh Tao boat day feels like

This is a value-focused snorkeling trip, not a quiet private cruise. For $27.71 per person, you get transport, equipment, food, several swimming locations, a guide, and photos. That is a strong package if you want to see a lot of Koh Tao without arranging boats, taxis, meals, and masks separately.

The tradeoff is pace. You will move from bay to bay, climb at Koh Nangyuan, eat on the boat, and spend roughly an hour at several snorkeling spots. The schedule gives you variety, but it does not leave much room for lingering in one place.

You start with pickup from your hotel lobby and a ride to Mae Haad Pier. The tour crew from Sangthong Tours meets you there, and a quick health check takes place before boarding the modified fishing cutter. Hotel transfers are included except for accommodation at Mango Bay and Lighthouse Beach, so check that detail before booking.

The boat returns to Mae Haad Pier at the end. The advertised maximum is 60 people. A separate booking detail refers to a maximum of 15 people per booking, not necessarily 15 people on the boat, and one account describes a group of about 50. If you want silence, space, and a personal guide, look for a private trip instead. If you mainly want a practical day on the water, the larger boat helps keep the price down.

Koh Nangyuan brings the big first impression

The first major stop is Koh Nangyuan, off Koh Tao’s northwest coast. Three small islands are linked by a narrow beach, creating one of the most recognizable views in the area. You get about 90 minutes here, enough time to walk the beach, swim in one of the separate swimming areas, and climb to the viewpoint on the highest island.

The viewpoint is worth the effort. From above, you see the curved strip of sand joining the three rocky islands, a classic Koh Tao scene that looks especially good in photographs. A guide may climb with you and help take pictures, which is handy if you are traveling without someone to operate your camera.

There is a price attached to this famous stop. The entrance fee is not included: adults pay THB 250, while children pay THB 120. Children taller than 120 centimeters are charged the adult rate. That extra fee makes Nangyuan less of a surprise bargain, but the beach and viewpoint are still central reasons many people choose this tour.

This stop can also feel crowded, since Koh Nangyuan is a popular destination. You may find the viewpoint busy and the beach less peaceful than the photographs suggest. Still, the combination of a short walk, swimming, and a strong view gives this stop more variety than a standard snorkel-only outing.

Mango Bay adds a scenic meal stop

The boat then heads toward Mango Bay on Koh Tao. The bay took its name from mango trees that once grew here in large numbers. The setting is framed by rocky slopes, and the water provides another place to look for coral and fish.

A Thai-style lunch is served on board while you make your way to the bay. This works well for a full-day trip because you do not lose an hour searching for a restaurant or waiting for food on shore. The included meal is simple rather than fancy, but it does the job, and fruit, drinking water, coffee, tea, and snacks help fill the gaps.

Do not treat Mango Bay as a guaranteed stop. The route depends on wind, waves, and other sea conditions. On some days, the crew substitutes another bay. That may disappoint you if Mango Bay is the place you most want to see, but changing the route is safer than forcing a boat into uncomfortable water.

The boat ride itself is part of the experience. You get changing views of Koh Tao from the sea, though the modified fishing cutter is still a working-style boat rather than a luxury yacht. Bring only what you need. Dry bags or waterproof pouches are sensible for phones and valuables, even though snorkeling equipment and life jackets are supplied.

Hin Wong Bay is best for underwater structure

Hin Wong Bay sits on Koh Tao’s east coast, surrounded by large boulders. Beneath the surface, underwater pinnacles support coral, anemones, and many kinds of fish. You usually get about an hour here, which is enough for a proper swim if you enter the water promptly.

This stop rewards people who like looking closely rather than simply floating over a sandy bottom. The rocks create more interesting underwater shapes, and the coral-covered pinnacles give fish places to gather. Conditions matter a great deal, though. Strong current or choppy water can make even a beautiful site hard to enjoy.

One useful piece of advice comes directly from the trip’s practical nature: listen to the guide about the water and wear a life jacket if you need one. You do not have to prove anything by swimming without support. Rough seas have made some people uncomfortable, and the guide’s job is to keep the group together and point out marine life safely.

The English-speaking guides are one of the tour’s strongest features. Curb is named as a guide connected with the experience, and several accounts describe the staff as friendly, helpful, and eager to show people fish and turtles. That matters at a site like Hin Wong, where a guide’s pointing hand can help you notice animals you would otherwise swim past.

Aow Leuk offers a calmer-looking beach setting

The next stop is Aow Leuk, a deep, curved bay on Koh Tao’s southeast side. Its shape gives it a sheltered appearance, with white sand and clear water bordered by rocky scenery. The bay is also known for remaining suitable for snorkeling at low tide because the water is relatively deep.

You get about an hour here. Aow Leuk provides a pleasant change from rockier snorkeling areas, and the beach makes it a good place to pause between swims. The water may look inviting, but do not assume every day will be calm. Wind direction and tide can alter the experience.

If you are new to snorkeling, this is the kind of stop where the included equipment and guide are useful. A mask that fits badly can ruin an otherwise good day, so ask the crew for help before you swim far from the boat. Life jackets are available, and basic accident insurance is included, though that should not replace sensible behavior in the water.

The tour does not promise a particular number of fish or coral species. You might see colorful fish, coral, anemones, turtles, or sharks, but wildlife changes from day to day. The best approach is to enjoy the setting and treat a turtle sighting as a bonus rather than a guarantee.

Shark Bay can provide the day’s best wildlife

Before heading back to Mae Haad Pier, the boat stops near Shark Bay for about 45 minutes. This is the shortest listed water stop, but it may be the most exciting. Blacktip reef sharks and sea turtles visit the bay, and several people have been able to swim near turtles there.

The name can sound more alarming than the experience. Blacktip reef sharks are part of the bay’s natural life, and the guide will help you understand where to swim and how to behave. You should follow instructions closely, stay with the group, and avoid treating wildlife as a photo prop.

Turtle sightings have been a high point for this trip. Some days produce encounters with several turtles, while other days offer only one or none. One person described seeing four turtles at Shark Bay, while other accounts mention baby sharks, colorful fish, and a single turtle. That range gives you a fair expectation: the bay has real wildlife potential, but nature does not run on a tour timetable.

The free underwater photos are especially useful here. Guides can take pictures while you focus on swimming, and the images are sent to you after the trip. Ask how and when the files will arrive before leaving the boat, and keep your contact details accurate when booking.

Food, gear, and safety keep the price practical

The included equipment saves you the trouble of renting a mask, snorkel, and life jacket on your own. You also receive drinking water, coffee, tea, fresh fruit, and a Thai lunch box. For a seven-hour outing, those inclusions make the low price easier to justify.

Lunch is described as tasty or good, though it is still a basic boxed meal served on a boat. If you have dietary restrictions, the supplied information does not confirm special meal options, so ask the provider before booking rather than assuming.

The boat is a modified fishing cutter. Some people find this style comfortable and others find the movement tiring, especially in rough seas. One account describes a newer, comfortable boat, while another describes the sea as difficult on some days. Both can be true because conditions and boats may vary.

A health check takes place before boarding, and basic accident insurance is included. That is reassuring, but the most useful safety measure is still following the guide’s instructions. Wear the life jacket if you feel unsure, especially at Hin Wong Bay or when the sea is moving.

Weather decides more than the brochure does

The order and identity of stops can change because of weather and sea conditions. Mango Bay may be replaced by another bay, and rough water can affect how long you comfortably swim. The crew’s response to bad conditions is part of the value of a guided tour, since you are not left to judge every bay yourself.

The best day will come with calm water and good visibility. Under those conditions, the snorkeling can feel aquarium-like, with coral, fish, turtles, and perhaps small sharks. On a less favorable day, you may see fewer animals and spend more time managing waves, but the beach stops and boat views still give the day some variety.

The tour can be canceled for poor weather. You are offered another date or a full refund in that situation. If you cancel, you need to do so at least 24 hours before the start time for a full refund. Changes or cancellations inside that window are not accepted.

Who will get the most from this tour

I would choose this trip if you want many stops for one low price and prefer having transport, food, gear, and guidance handled together. It suits first-time snorkelers, couples, families whose children meet the participation rules, and anyone with only one free day on Koh Tao.

It is also a good match if you want more than a single beach. Koh Nangyuan adds a viewpoint and beach walk, while the four Koh Tao bays offer different coastal settings and underwater conditions.

I would think twice if you dislike group outings, get seasick, or need a slow and quiet schedule. The boat can carry up to 60 people, and the full route involves repeated boarding, swimming, and movement. You should also budget for the Koh Nangyuan entrance fee, since the advertised price does not cover it.

Should you book the five-island Koh Tao tour?

Book it if your priority is value, variety, and a straightforward day on the water. The combination of five named areas, lunch, hotel transfer, equipment, an English-speaking guide, insurance, and free underwater photos is unusually useful at $27.71.

Skip it if your heart is set on Mango Bay specifically, because weather may change the route. Also skip it if you want a small boat and private attention. For everyone else, this is a sensible way to see Koh Tao’s coast, with Shark Bay and Koh Nangyuan providing the strongest reasons to go and the large group size providing the main reason to manage expectations.
