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

The best part of this Koh Chang boat trip is the balance: you get real time in the water, a white-sand beach stop, and a comfortable big boat rather than a cramped speedboat. The 4-island route adds three snorkel sites around Koh Rang National Park, while the 3-island route is a shorter and cheaper way to sample the area.

I like the freshly prepared Thai lunch and the crew’s practical help in the water. I also like having shade, toilets, room to sit, and an underwater photographer onboard. One thing to consider: fins are not included, and rough seas can make the ride uncomfortable.

Quick points to know before you book

• Two useful route choices: Pick the 3-island tour for about 5.5 hours, or the 4-island trip for about seven hours before transfers.
• Three snorkel stops on the longer route: Koh Yak Lek, Koh Mapring, and Koh Yak Yai sit around Koh Rang National Park.
• A proper beach break: Both options include about an hour to swim and relax on shore or near a beach.
• Lunch is cooked on the boat: Expect a basic chicken-based Thai meal, fruit, water, and coffee.
• Pickup saves time: Shared hotel transfers cover Koh Chang’s west coast as far north as White Sand Beach.
• Bring cash for the park fee: The 4-island option costs an additional 200 baht per adult or 100 baht per child aged 5 to 9.

Choosing between the 3-island and 4-island routes

The 3-island tour starts around 10:30 AM and returns around 4 PM. It visits Koh Wai, Koh Lao Ya Nai, and Koh Klum, with two snorkel stops and about an hour at a beach.

This is the sensible pick if you want a half-day on the sea without giving up most of your afternoon. It also suits families who want snorkeling, swimming, a little open-sea fishing, and a manageable schedule. At about $28 per person, it gives you a lot for the money, especially with lunch and hotel transport included.

The 4-island tour starts earlier, around 9:30 AM, and returns around 4:30 PM. It travels roughly 1.5 hours from the pier to Koh Rang National Park, then visits Koh Yak Yai, Koh Mapring, Koh Rang, and Koh Yak Lek. In practice, this means one larger island and three smaller islets close together.

Choose this route if snorkeling is the main reason you are booking. You get three 40-minute water stops plus a one-hour beach break. The extra time on the boat is worth it for people who want more fish, coral, and swimming rather than a quick taste of the coast.

The tradeoff is simple. The 4-island route costs the national park fee and uses more of your day. The islets are close together, so the scenery changes less dramatically than the island names might suggest. You are buying more water time, not four completely different worlds.

Leaving from Bang Bao Pier

If you arrange your own transport, the meeting point is at Bang Bao Pier. You are asked to arrive at 10 AM, though the actual departure time depends on your selected tour. Leave extra time because the walk from the parking area to the boat can be long.

Parking at the meeting point is free according to the tour details, though a parking charge of around 70 baht may apply if you arrive by your own car or motorbike. The clearest practical tip is to bring cash and wear footwear that can handle a walk near the pier.

Hotel pickup is available from the west side of Koh Chang, up to White Sand Beach. For the 3-island trip, shared pickup runs roughly from 9 AM to 9:50 AM. For the 4-island trip, pickup is earlier, roughly 8 AM to 8:50 AM. Drop-off times vary because the vehicle returns several people to different resorts.

If you stay on Koh Chang’s north or east side, transfers are not available. You will need to book the no-transfer option and arrange your own ride to Bang Bao Pier. Be ready at the pickup time. The driver may wait a few minutes, but a late arrival can be treated as a no-show.

The big boat makes a difference

This is not a fast, sleek speedboat outing. The large boat has more seats, more room to move around, covered areas, a toilet, and space to sit in either sun or shade. That matters on a full day at sea, especially when you have wet towels, snorkeling gear, children, or a mixed group of swimmers and non-swimmers.

The boat is not private, and it can feel busy at times. A few people found the transport truck packed, and some felt the boat had more people than ideal. Still, the big-boat format gives you a steadier base than a small craft, with room to rest between water stops.

The ride can be bumpy when the sea is rough. If you get motion sick, bring medication or ask the staff about the sea-sickness pill they offer. Sit in a covered area, keep your eyes on the horizon, and avoid arriving on an empty stomach.

The tour schedule can change with weather and sea conditions. Rain can arrive quickly in Thailand, especially during monsoon months. If conditions are unsafe, the trip can be canceled, rescheduled, or refunded.

What happens at the snorkeling stops

The crew provides masks and life jackets. Fins are not listed among the included equipment, and several people wished they had been available, so strong swimmers may want to ask in advance or bring their own if possible.

The water stops usually last about 40 minutes. That is enough time to swim out, look over the reef, and return without feeling rushed. Guides point out areas where fish gather, and crew members are active in the water. They have also helped children and non-swimmers feel secure, including staying alongside a child for much of the session.

At Koh Yak Lek, Koh Mapring, and Koh Yak Yai, you can expect warm water, fish, coral, and clear conditions when the sea is calm. The coral is attractive, but do not book this as a substitute for a serious scuba trip. Some sites have more color and life than others, and people with extensive reef experience may find the formations modest.

Koh Rang is the main attraction on the longer route. It gives you access to several snorkel areas within the national marine park, with the small islets nearby. The stops are close together, which keeps boat time between swims short but means you may see similar reef conditions more than once.

The 3-island route offers a slightly different rhythm. Koh Wai and Koh Klum provide water time, while Koh Lao Ya Nai gives you an hour to relax and swim. Open-sea fishing is also part of the shorter adventure, a small extra that children often enjoy.

The boat’s entry points may not always make shore access easy. At one beach, the pontoon did not reach all the way to the sand, so non-swimmers or anyone with limited mobility may prefer to remain on the boat. This is not a wheelchair-friendly excursion.

Beach time at Koh Rang and Koh Lao Ya Nai

Snorkeling takes the spotlight, but the beach stop prevents the day from becoming a string of swims. On the 4-island route, you get about an hour at a white-sand beach near Koh Rang. This is your chance to dry off, walk a little, sit under the sun, or simply float in clear water.

On the 3-island route, Koh Lao Ya Nai offers the main beach break. The turquoise water and soft sand give families a calmer place to get comfortable before or after the offshore stops.

The beach time is not a private-island experience. Other boats may be nearby, and conditions affect how close the boat can get to shore. Still, one hour is long enough to make the stop feel useful rather than decorative.

Wear water shoes if you plan to walk on shore. The sand and ground can become very hot, and some entry points may be rocky or awkward. Bring a towel, sunscreen, sunglasses, and a dry change of clothes.

Lunch, fruit, and the onboard routine

Lunch is freshly prepared on the boat and served as a basic Thai meal. It is chicken-based, with water and coffee included. Fruit, including watermelon and pineapple, is served later as a snack.

The food is better than the low price might suggest, but keep your expectations realistic. This is boat catering for a large group, not a restaurant meal. Vegetarian food can be arranged if you tell the operator one day before departure. A special dietary request should be made early rather than left to the morning of the trip.

You can buy extra drinks and snacks onboard, including beer, soda, crisps, and noodles. Bring cash for these purchases, the national park fee, and any other spending at the pier.

One sensible precaution is to use sunscreen and drink water regularly. You may not feel the heat while swimming, but the boat’s deck and beach stops expose you to the sun for hours.

Underwater photographs and crew support

A professional photographer accompanies the trip and takes candid boat pictures as well as underwater images. This is a nice addition because you can focus on swimming instead of trying to protect a phone in a waterproof case.

Tell the guide clearly that you want your picture taken. The photographer may not reach every person at every stop, and one practical complaint was that some people finished the trip without photos because they had not asked. Also ask the crew how the images will be provided before you leave.

The staff generally keep the day moving without making it feel frantic. They give safety instructions, direct you toward fish, and help nervous swimmers. One guide has even been seen catching a fish during the trip, which gives the open-sea fishing option a bit of local character.

English is the stated tour language. Instructions can be hard to hear over the motor, and one person found the main guide spoke too quickly. If you miss something, ask the crew to repeat it before entering the water. A short question is better than guessing about where to swim.

How much value do you get for $28?

At roughly $28 per person, this is strong value if you use the included services. You are paying for a boat ride, guide, snorkeling mask and life jacket, lunch, fruit, drinks, hotel transfer if you are on the west coast, and access to several islands.

The 3-island option is especially good value for a family or first-time snorkeler. You get a beach break and two water stops without committing to a long day. The 4-island tour asks for more time and adds the 200-baht adult park fee, but the extra snorkel location makes sense if the sea is your main reason for visiting Koh Chang.

The price also explains some compromises. The boat is shared, the meal is simple, fins are not included, and the route follows a set schedule. You are not paying for a private charter or a quiet, custom itinerary.

The overall rating is 4.3 from 723 ratings, which fits the experience: strong organization and friendly crew, with occasional crowding, rough water, fast announcements, and reef quality that varies by site.

Who should book this Koh Chang boat trip?

You should book it if you want an easy day on the water with transport, food, equipment, and several swim stops handled for you. It suits couples, families with older children, first-time snorkelers, and non-swimmers who want the option to stay onboard while the rest of the group swims.

The 3-island tour is best for a shorter day, families, or anyone who wants to combine snorkeling with open-sea fishing and a beach stop. The 4-island route is better for confident swimmers and people who want the most snorkeling included.

Think twice if you need a private boat, a quiet beach with no other groups, full scuba-quality coral, wheelchair access, or guaranteed calm seas. Children under 2, pregnant people, wheelchair users, and people with back problems should not book this activity.

Cancellation is free up to 24 hours before departure, and you can reserve now and pay later. That flexibility is useful during unsettled weather, but you should still check the forecast and keep the day after the tour free if possible.

Should you book it?

I would book the 3-island tour for a relaxed introduction to Koh Chang’s surrounding waters, and the 4-island option if snorkeling is the main event. The combination of a spacious boat, helpful crew, cooked lunch, beach time, and underwater photography gives you more than the price suggests.

Bring cash, water shoes, sunscreen, swimwear, a towel, and motion-sickness medicine if you need it. Tell the crew about vegetarian food and ask for photographs early. With those small preparations, this is an easy, good-value way to spend a day away from Koh Chang’s beaches.
