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

Clear water, simple pleasures, good value. This Koh Chang boat trip combines colorful snorkeling, warm swimming, island beaches, and a freshly prepared Thai lunch for about $28. I especially like the spacious boat and the choice between a shorter three-island outing and a fuller four-island day.

The crew provides masks, life jackets, fruit, water, coffee, and an underwater photographer. The main tradeoff is comfort at sea: big waves can make the ride rough, and some departures feel crowded. The snorkeling is excellent for a relaxed day trip, but serious reef enthusiasts may find some reefs less colorful than those at top scuba sites.

Key points to know before booking

• Choose the four-island trip for snorkeling: It reaches Koh Rang National Park and includes three snorkel stops plus a beach break.
• The three-island trip is shorter: You get two snorkel locations, one beach stop, and a chance to try open-water fishing.
• The boat has real room to move: You can sit in sun or shade, with toilets and space for a full day at sea.
• Lunch is better than basic tour food: Chicken, rice, fruit, water, and coffee are included, with vegetarian meals available if requested one day ahead.
• Hotel pickup has a strict range: Transfers cover the west coast of Koh Chang only, up to White Sand Beach.
• Bring cash for extras: The four-island trip has a 200-baht national park fee for adults, plus about 70 baht parking if you drive.

Choosing between three islands and four

The operator offers two versions of the trip, and the choice matters more than the name suggests. The three-island option is a shorter outing from 10:30 a.m. to 4 p.m. The four-island trip runs from 9:30 a.m. to 4:30 p.m., with a longer journey to the Koh Rang area.

I would choose the three-island trip if you want a pleasant half-day on the water without giving up an entire morning. It suits families, first-time snorkelers, and anyone who wants some beach time mixed with swimming.

The four-island trip is the better pick if snorkeling is your main reason for booking. It reaches one larger island and three smaller islets around Koh Rang National Marine Park. You spend more time in the water and get three snorkeling locations rather than two.

The four-island route costs an additional 200 baht per adult for the national park entrance fee, or 100 baht for children aged 5 to 9. That extra cost is modest, especially if you want the best underwater portion of the outing.

Starting from Bang Bao and getting aboard

Hotel pickup is available on the west side of Koh Chang. For the three-island trip, shared transport generally collects you between 9 and 9:50 a.m. For the four-island trip, pickup is earlier, between 8 and 8:50 a.m.

If you stay on the north or east side, you need to arrange your own way to the meeting point at Bang Bao Pier. The meeting point has free parking for cars and motorbikes, although the information also notes a parking charge of around 70 baht if you arrive with your own vehicle. Confirm the current parking arrangement when booking.

The walk from the parking area to the boat can take time, so arrive early. The meeting-point instruction asks independent arrivals to be there at 10 a.m., and arriving late is risky. A shared driver may wait briefly for a late hotel pickup, but after that the booking can be marked as a no-show.

The transfer is practical rather than luxurious. A shared truck can feel packed, and the road to the pier is bumpy and windy. That is part of getting around Koh Chang, and the transport is included for eligible hotels.

Once aboard, the large boat gives you a better base than a small speedboat. You have covered areas, open seating, a toilet, and enough room to sit out between water stops. The boat can still feel crowded on a busy departure, but it is generally more forgiving than a narrow speedboat when you are spending several hours offshore.

The three-island route: Koh Wai, Koh Lao Ya Nai, and Koh Klum

The three-island tour reaches its first area in about 40 minutes. The route includes Koh Wai, Koh Lao Ya Nai, and Koh Klum, with two snorkeling stops and a separate one-hour beach break.

Koh Wai is used for swimming and snorkeling. The appeal here is an easy introduction to the water, with warm conditions and fish around the reef. If you are nervous, tell the crew before entering. Staff have helped children and non-swimmers in the water, and life jackets are available.

Koh Lao Ya Nai provides the relaxed beach portion. You get about an hour to swim, sit on the sand, and enjoy the turquoise water without being rushed straight back onto the boat. Families may appreciate this pause, especially if younger children need a break from snorkeling.

Koh Klum is part of the same compact island area and supports the snorkeling and swimming program. Some departures also offer simple reel fishing in open water. It is not a full fishing expedition, but children often enjoy having something to do between swimming stops.

The strength of this route is its balance. You are not spending the entire day moving between distant locations, and the schedule leaves space for a beach stop. The limitation is that you see fewer reef areas than on the four-island route.

The four-island route: Koh Rang and its smaller islets

The four-island trip travels about one and a half hours from the pier to the Koh Rang area. That longer ride is worth keeping in mind before you book. You get more snorkeling, but also more time exposed to wind and waves.

The route includes Koh Rang, Koh Yak Yai, Koh Mapring, and Koh Yak Lek. The three smaller islets are close to one another, so this is not four widely separated island visits. Instead, you explore several nearby snorkel areas around the national park.

Koh Yak Lek and Koh Mapring each allow around 40 minutes for swimming and snorkeling. These stops give you time to look for fish and coral without treating the water as a quick photo stop.

Koh Rang includes about an hour for visiting, swimming, and free time. This is also the main beach pause on the four-island option. Pack water shoes if you have them. The sand and ground can feel hot, and one snorkeling area may be shallow enough that careful footing matters.

Koh Yak Yai adds another 40-minute snorkeling session. The benefit of having three water stops is variety. Even when the reefs appear similar, visibility, fish, and coral formations can change from one location to the next.

The four-island route is not a luxury reef expedition. If you have spent time scuba diving in famous sites, you may find the coral colors modest. You will still see fish, coral, and clear warm water, and the setting makes this a strong choice for a casual snorkeling day.

What the snorkeling is really like

The snorkeling is the heart of the trip. The water is usually warm, and several departures have had clear conditions even during rainy season. The crew points out where to swim, and staff members enter the water to help guests and show them marine life.

Masks and life jackets are included, but fins are not listed among the equipment. Several people wished fins were provided. If you are a strong swimmer, this may not bother you. If you tire easily, fins would make it easier to cover distance and stay comfortable.

You do not need to be an expert swimmer to participate, but you should tell the crew if you need help. Staff have supported non-swimmers and children in the water. The life jackets also make it easier to float while looking down at the reef.

The underwater photographer is a useful extra. Photos may include shots from the boat and underwater images while you snorkel. One practical tip: tell the guide clearly that you want your picture taken. The photographer cannot catch every person automatically, and one guest ended up with no images after missing the instructions.

Expect a group snorkeling setup rather than private guiding. The crew can indicate good areas, but you will be sharing the water with other people. At some stops, the boat may be busy and the reef may feel less peaceful than a private charter.

Lunch, fruit, and the surprisingly useful extras

Lunch is prepared on the boat and included in the price. It is chicken-based, with water, coffee, and fruit also provided. The meal is simple, but it has earned unusually warm praise for an included boat lunch.

Fresh pineapple and watermelon are served later, which is welcome after swimming in the sun. Some trips also have drinks, noodles, crisps, beer, and soft drinks available for purchase. Bring cash if you want those extras.

Vegetarian food is possible if you notify the operator at least one day before departure. A gluten-sensitive vegetarian meal has been arranged successfully, but you should still give clear notice before the trip rather than hoping the crew can improvise at sea.

The food adds real value at this price. You do not need to find lunch on an island, and the meal arrives when you are already ready for it. Just bring snacks if you have a large appetite or dietary needs that require more than the standard meal.

Timing, weather, and comfort on the water

The advertised duration ranges from 330 minutes to nine hours, depending on the selected option and transfer arrangements. The actual three-island schedule is roughly five and a half hours, while the four-island outing is about seven hours before considering hotel transfers.

The boat has shaded seating, which matters in Thailand’s strong sun. Bring sunscreen, sunglasses, swimwear, a towel, and cash. A dry bag would also be sensible for phones and valuables, although it is not listed as required equipment.

Sea conditions can change the character of the day. In calm weather, the large boat offers a smooth and social ride. With big waves, it can become bumpy and uncomfortable, especially on the longer run to Koh Rang.

Rain can arrive quickly, particularly during monsoon season. A wet day does not automatically cancel the outing, but unsafe conditions can lead to cancellation, rescheduling, or a full refund. The tour schedule may also change to match the sea.

If you are prone to seasickness, ask the staff about the seasickness pill they offer. One person specifically found the boat moved a lot. Take precautions before the ride rather than waiting until you feel ill.

Service, safety, and the group atmosphere

The crew is one of the strongest parts of the experience. Staff help swimmers, keep an eye on children, provide instructions, and guide people toward better snorkeling areas. Several families appreciated the patient support in the water.

Instructions can be hard to hear over the motor, especially when the guide speaks quickly. If you miss something, ask for it to be repeated. The crew is usually friendly and helpful, but the quality of communication may depend on where you are sitting and how busy the boat is.

The boat is not a private outing. Some people found it a little crowded, while others felt there was enough room for everyone. If you want quiet, personal service, or long stretches alone on the beach, this is not the right format.

For a public boat trip at this price, the organization is generally strong. Pickup, boarding, lunch, equipment, and multiple water stops are handled in one package. The occasional weak point is not safety but communication, especially when instructions are delivered quickly or the itinerary changes with conditions.

Is $28 a good deal?

At about $28 per person, this is strong value if you want a full activity rather than a private charter. The price includes boat transport, a guide, snorkeling gear, a toilet, lunch, fruit, water, coffee, hotel pickup and drop-off where available, and an underwater photographer.

The three-island option gives you a shorter day at a low cost. The four-island trip adds the national park fee, but you receive an extra snorkeling stop and more time around Koh Rang. Either option costs less than arranging separate transport, meals, and boat access on your own.

The price also explains the compromises. You share the boat, the beach, and the snorkeling sites. Fins are not included, and the food is a practical group meal rather than a restaurant lunch.

I would call it particularly good value for families and couples who want an easy day with everything arranged. It is less compelling for experienced snorkelers seeking untouched reefs, private guiding, or a small group.

Who should book this Koh Chang boat trip?

Book the three-island option if you want a manageable outing with beach time, swimming, snorkeling, and a little fishing. It is a good introduction for first-time snorkelers and families who do not want a long day offshore.

Choose four islands if you care most about time in the water. The Koh Rang National Park setting, three snorkeling locations, and white-sand beach make it the stronger route for marine life.

This trip also works well for non-swimmers because the crew can assist, and you can remain aboard or watch from the beach. Pregnant women, children under two, wheelchair users, and people with back problems should not book it.

Should you book it?

Yes, if you want an affordable, well-organized day from Koh Chang with warm water, island beaches, a filling lunch, and plenty of swimming. I would pick the four-island route for serious interest in snorkeling, and the three-island route for a shorter, more relaxed schedule.

Skip it if you dislike group boats, get badly seasick, or expect dramatic coral color at every stop. For most visitors, the combination of friendly help, spacious boat seating, fresh food, and several chances to snorkel makes this one of Koh Chang’s better-value water outings.
