Koh Chang: 3 or 4 Islands Snorkel & Beach Tour by Big Boat

Koh Chang’s best water day is not about racing from one postcard beach to the next. It is about settling onto a roomy boat, eating lunch cooked onboard, and spending real time in warm water with fish and coral below you. The 4-island route reaches Koh Rang National Park, while the shorter trip offers a gentler introduction to snorkeling.

I like the space and shade on the big boat, a useful luxury when the sun is strong or the sea turns choppy. I also like the practical touches: hotel transfers from the west coast, fresh fruit, a toilet onboard, and a photographer who can take underwater pictures. The catch is that the boat ride can be rough in windy weather, and the snorkeling reefs may look modest if you have already visited top coral sites elsewhere.

The trip in five useful points

• Two routes: Choose three islands from 10:30 AM to 4 PM, or four islands from 9:30 AM to 4:30 PM.
• Koh Rang National Park: The longer route includes three snorkeling stops around one larger island and three smaller islets.
• Fresh lunch onboard: Expect a simple chicken-based Thai meal, fruit, water, and coffee.
• Underwater photos: A photographer joins the boat, but tell the guide clearly that you want your pictures taken.
• Bring cash: The 4-island tour requires a 200-baht adult park fee, and drinks or snacks may cost extra.

Choosing between three islands and four

The first decision is easy. Pick the 3 Islands Tour if you want a shorter day, less time on the water, or a relaxed first try at snorkeling. Pick the 4 Islands Tour if the underwater world is the main reason you are booking.

The 3-island trip runs from about 10:30 AM to 4 PM. The boat reaches the islands in roughly 40 minutes from the pier, then visits Koh Wai, Koh Lao Ya Nai, and Koh Klum. You get two snorkeling locations where you can also swim toward shore, plus about an hour at a beach for swimming and rest. Open-sea fishing may also be offered, which gives children and non-snorkelers something else to enjoy.

The 4-island tour starts earlier, around 9:30 AM, and finishes near 4:30 PM. The ride from the pier takes about an hour and a half, so this is a longer day with more time spent getting there and back. In exchange, you visit Koh Rang National Park and stop at Ko Yak Lek, Ko Mapring, Koh Rang, and Ko Yak Yai.

One important detail: the 4-island name can sound grander than the route really is. You visit one larger island and three small islets close together around Koh Rang. That is good news if you want several water stops without long transfers between each one. It also means you should not expect four entirely different island worlds.

Boarding at Bang Bao Pier

Hotel pickup is available only from Koh Chang’s west side, as far north as White Sand Beach. For the 3-island option, shared-car pickup generally runs between 9 and 9:50 AM. The 4-island pickup runs earlier, between 8 and 8:50 AM.

If you stay on the north or east side, book the option without transfers and arrange your own ride to the meeting point at Bang Bao Pier. The meeting point has free parking for a car or motorbike, although the information also notes a parking charge of around 70 baht if you arrive independently, so confirm the current arrangement when booking.

Arrive on time. The walk from the parking area to the boat can be long, and a late pickup may wait only a few minutes before marking the booking as a no-show. This is not the place for a leisurely breakfast after your stated pickup time.

The shared vehicle can feel packed, especially on the winding road to the pier. That is a minor tradeoff for having transport included in the $28 price. If you are carrying luggage, ask ahead about storage. A previous passenger was able to use the service with different pickup and drop-off points and had luggage stored, but do not treat that as guaranteed for every departure.

Why the big boat matters

The boat is a major reason this tour works well for a full day on the sea. It has more room than a small speedboat, with seating in sun and shade, a toilet, and enough deck space to move around between stops. At $28 per person, you are not paying for a private charter, so expect other people onboard. Still, the boat is not described as painfully crowded on most departures, and the extra room makes the day easier for families.

The larger boat also gives you a steadier place to eat lunch and dry off. The ride can still be bumpy when waves pick up. If you get seasick, ask the crew about the motion-sickness pill they offer, and sit in the most stable area you can find rather than staying at the very front.

I would pack a towel, swimwear, sunscreen, sunglasses, snacks, and cash. Water shoes are useful for beaches and rocky or hot ground. One stop may have a beach access point that is not ideal for people with limited mobility, and the boat’s pontoon may not reach the sand at every landing.

Koh Wai and the gentler three-island route

Koh Wai is one of the 3-island route’s snorkeling and swimming stops. The appeal here is simplicity: get into the water, look for fish over the reef, and swim ashore if conditions allow. This can be a good first stop for children because you can build confidence near the beach instead of beginning in open water.

The stop is scheduled for about 40 minutes, so you have enough time to snorkel without feeling hurried, but not enough time for a long beach stay. The 3-island tour then gives you another water stop and a separate hour on a beach, creating a useful mix of activity and rest.

Koh Lao Ya Nai is the main beach break on this route, with about an hour to swim and sit by turquoise water. It is the point where the shorter tour feels like a proper island day rather than only a series of quick jumps into the sea. Koh Klum completes the route, with another chance to snorkel and possibly try open-sea fishing.

I would choose this route for a family group with mixed interests. Strong swimmers can snorkel, children can try fishing, and anyone who prefers not to enter the water can enjoy the boat or beach. The shorter hours also make it easier for anyone who does not want a full day exposed to sun and sea.

Koh Yak Lek and Koh Mapring in Koh Rang National Park

The longer route begins its snorkeling around Koh Rang National Park. Ko Yak Lek and Ko Mapring each receive about 40 minutes for swimming and snorkeling.

These smaller islets are close to one another, so you will not get a long pause between them. That is good for anyone who wants to maximize water time. It is less good if you imagine spending quiet stretches alone on separate beaches. Several stops can feel similar, with the main reward coming from fish, coral, and clear warm water rather than a dramatic change of scenery.

The crew helps point out better places to look underwater. That matters because a reef can seem empty if you simply swim in a random direction. You may see many small reef fish and coral formations, and some departures have included memorable sightings such as a turtle. Conditions change with weather, tide, and visibility, so no sighting is promised.

Fins are not included in the listed equipment. You receive a mask and life jacket, and several people wished fins had been available. If you are a weak swimmer, the life jacket helps, but fins would make it easier to move against a current. Ask the operator if separate fins can be arranged before you go.

Koh Rang beach time

Koh Rang is the longer route’s main one-hour visit. This is the place to stop chasing fish and enjoy the setting. The water can be exceptionally clear and blue, and the white-sand beach gives you a proper break from the boat.

The beach stop also helps balance the 4-island itinerary. Three snorkeling sessions can leave you sun-tired, even when the water feels comfortable. Use this hour to drink water, eat fruit, and let your skin dry before returning to the boat.

Beach access may not suit everyone. The pontoon does not always reach all the way to shore, and getting off can involve a wet or awkward step. Children should be watched closely, and non-swimmers should tell the crew what help they need. The staff have assisted people who could not swim, but you should still be honest about your ability before entering the water.

Ko Yak Yai and the final snorkeling stop

Ko Yak Yai provides another 40-minute swimming and snorkeling session. By this point, you will have spent a good amount of time in the water, so the final stop works best if you pace yourself earlier.

Some people find the reefs close together and similar in character. Others appreciate seeing the same broad setting from different angles, since the fish and coral change from one patch to the next. One location may be shallow, which is useful for beginners but less exciting for confident snorkelers.

Do not judge the tour only by the coral color. The reefs may not satisfy someone comparing them with famous scuba sites. The water, fish, warm temperature, and easy access still make this a worthwhile day for a first snorkeling experience or a simple break from Koh Chang’s beaches.

Lunch, fruit, and what the $28 covers

The included lunch is basic but freshly prepared on the boat. It is chicken-based, and you should request a vegetarian meal at least one day ahead. A meal, fruit such as watermelon and pineapple, drinking water, and coffee are included.

I would set expectations correctly. This is not a restaurant lunch with several courses. It is a practical meal served to a boat full of people, and the food has been a pleasant surprise for many people. There may also be noodles, crisps, beer, and soft drinks for purchase onboard, so carry cash if you want extras.

At $28, the value is strong. The price includes shared transport on the west side, the boat, guide, mask, life jacket, toilet, lunch, fruit, water, coffee, and underwater photography. The 4-island option adds a 200-baht adult national park fee, or 100 baht for children aged 5 to 9. Children under 5 are not charged that listed child fee, but the activity is not suitable for children under 2.

The photographer and the practical details

The underwater photographer is a useful extra, especially if you do not own a waterproof camera. Photos may include candid shots on the boat and pictures taken while you snorkel.

There is one simple trick: tell the guide directly that you want photos. Do not assume every person will be called over at the right moment. The photographer may be busy with many people, and clear communication gives you a better chance of getting pictures.

The tour is conducted in English. Instructions can be hard to hear over the engine, especially when the guide speaks quickly. If you miss something, ask for the directions again before entering the water. Crew members are generally attentive in the water, including with children and people who are nervous, but you remain responsible for following safety instructions.

Weather, sea conditions, and who should book

Koh Chang’s weather can change quickly, especially in the monsoon season. Rain does not automatically ruin the day, and visibility can still be good, but waves can make the ride uncomfortable. If conditions are unsafe, the tour can be canceled, rescheduled, or refunded.

This trip suits you if you want an affordable, social day with swimming, snorkeling, a beach stop, and lunch included. It is also a good choice for families, mixed-ability groups, and first-time snorkelers who value crew support more than a private boat.

I would think twice if you want a quiet, uncrowded boat, highly dramatic coral, or a luxury meal. People with back problems, pregnant women, wheelchair users, and children under 2 should not book this activity. Non-swimmers can still enjoy the day, but tell the crew in advance and do not feel pressured to join every water stop.

Should you book this Koh Chang boat tour?

I would book the 3-island tour if you want the best value in a shorter format. It gives you two snorkeling stops, beach time, and the chance to fish without committing to the longer ride.

I would pay the extra time and park fee for the 4-island tour if snorkeling is your priority. The Koh Rang area, the three water stops, the white-sand beach, and the roomy boat make it a good full-day outing for $28 before the park charge. Just bring cash, expect shared-tour conditions, request vegetarian food early, and take seasickness precautions if you need them.
