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

Koh Chang’s best water time comes by big boat, with room to sit in sun or shade, a toilet onboard, and a full spread of swimming, snorkeling, and beach stops. The 3-island route keeps the day shorter, while the 4-island trip reaches Koh Rang National Park and gives you three snorkel sessions.

I especially like the fresh Thai lunch and fruit, which turn a low-cost boat trip into a proper day out, and the crew’s attention to nervous swimmers and children. The main tradeoff is comfort at sea: the ride can get bumpy, and the shared pickup truck may feel tight.

Key points to know before booking

• Three or four islands: Choose the 3-island trip for a shorter outing, or the 4-island route for more snorkeling around Koh Rang National Park.
• A spacious boat for $28: You get a toilet, covered seating, masks, life jackets, lunch, fruit, water, coffee, and hotel transfers from west-coast resorts.
• Three 40-minute snorkel sessions on the longer route: Koh Yak Lek, Koh Mapring, and Koh Yak Yai each offer time in the water.
• A proper beach break: The schedule includes about an hour at Koh Rang on the 4-island trip, or Koh Lao Ya Nai on the 3-island route.
• Underwater photos are included: Tell the guide clearly that you want your picture taken, since the photo service may not be explained to everyone.
• Bring cash: The 4-island trip costs an extra 200 baht for adults or 100 baht for children ages 5 to 9 for the national park fee.

Two routes from Bang Bao Pier

This tour gives you a useful choice rather than forcing every passenger into the same long day. Both routes use a large boat and include swimming, snorkeling, lunch, fruit, drinking water, coffee, and an English-speaking guide.

The 3 Islands Tour begins at 10:30 AM and returns around 4 PM. It takes roughly 40 minutes to reach the outer stops and visits Koh Wai, Koh Lao Ya Nai, and Koh Klum. You get two snorkel locations, opportunities to swim ashore, a one-hour beach stop, and the chance to try simple open-sea fishing.

The 4 Islands Tour leaves earlier, at 9:30 AM, and returns around 4:30 PM. The boat travels about 1.5 hours from the pier to the Koh Rang area, then works among Koh Rang, Koh Yak Yai, Koh Mapring, and Koh Yak Lek. The route includes three 40-minute snorkeling sessions and a one-hour beach break.

The 4-island name can be slightly confusing. The route includes one larger island and three small islets close together inside Koh Rang National Marine Park. The islands are not four far-flung destinations scattered across the sea.

At $28 per person, the price is strong for a full boat day. You still need to add the 200-baht park fee on the longer tour, plus about 70 baht parking if you arrive with your own vehicle. Even with those extras, the package covers the parts that often add up on a day at sea: transport, gear, lunch, water, and a guide.

Getting to the boat without a frantic start

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

If you stay on the north or east side of the island, book the option without transport and arrange your own ride to the meeting point at Bang Bao Pier. You can park at the meeting point, though the stated parking cost is around 70 baht if you arrive by car or motorbike.

The practical detail that matters most is the walk from parking to the pier. It is long enough that arriving at the last minute is a bad plan. The meeting-point instruction asks independent arrivals to come at 10 AM, but check the exact time attached to your chosen option because the 3-island and 4-island departures are different.

Pickup is shared, so the truck can feel packed. You will also encounter winding and bumpy roads on Koh Chang. That is part of the island transfer, not a sign that anything has gone wrong. Be ready before the driver arrives. If you miss pickup, the driver may wait a few minutes, after which the booking can be marked as a no-show.

What the big boat is really like

The boat is a major reason this tour works for the price. It offers more space than a small speedboat, with seating in both covered and sunny areas. You can move around, dry off between swims, and find shade when the tropical heat becomes too much.

A large boat also gives the ride a gentler rhythm in calm water. You are not packed into a narrow speedboat for the whole day. On rougher days, though, size does not erase the motion. Big waves can make the crossing bumpy and uncomfortable, and one useful tip is to accept a seasickness tablet from the crew if you need one.

The boat has a toilet, which is a small feature until you are several miles from shore. Snorkel masks and life jackets are provided. Fins are not listed as included, and several passengers wished they had been available, so strong swimmers should not assume they will receive a full set of fins.

The crew keeps the day moving, but the boat can still feel crowded during busy periods. That is the fair trade for a $28 outing with meals and transport included. You get a practical public boat experience, not a private charter.

Koh Yak Lek, Koh Mapring, and Koh Yak Yai

The longer route gives you three separate 40-minute snorkeling stops. That is enough time to get comfortable in the water, swim around the reef area, and look for fish without being rushed back aboard after ten minutes.

Koh Yak Lek is one of the small islets in the Koh Rang area. You can swim and snorkel here, with guides pointing out fish and directing you toward the better sections of the reef. If you are new to snorkeling, use the first stop to adjust your mask and breathing rather than trying to cover every corner.

Koh Mapring provides another 40-minute session. The stops are close together, so you will not get long scenic pauses between each one. That may disappoint anyone hoping for a slow island-hopping cruise, but it is useful if your main goal is time in the water.

Koh Yak Yai is the third snorkeling stop. The water is warm, and conditions can be clear enough to see coral, fish, shells, and other sea life. Some people have spotted unusual fish and even a turtle, though wildlife is never guaranteed.

The reefs may not satisfy a serious scuba diver looking for dramatic coral color and greater depth. One stop can feel shallow, and several sites have a similar look. Still, the combination of clear water, fish, and easy access makes the route a good introduction to snorkeling around Koh Chang.

If you are not a confident swimmer, say so early. The crew has helped children and adults in the water, and staff have carried or supported nervous swimmers so they could take part. You should still wear the life jacket and follow instructions closely.

Koh Rang National Park and the white-sand pause

The one-hour stop at Koh Rang gives the 4-island route its best change of pace. After the repeated swim sessions, you can sit on the white sand, walk a little, or simply cool off in the clear water.

The beach is also helpful for children who are building confidence. Starting with shallow water near shore can feel less intimidating than stepping straight from the boat into open sea. Bring water shoes if you have them. The sand and ground can become hot, and rocky or uneven access may make bare feet unpleasant.

Getting ashore is not always effortless. The floating pontoon may not reach the beach at every stop, and passengers who cannot swim might find the transfer awkward. Ask the crew for help rather than attempting an unstable step on your own.

The 3-island trip uses Koh Lao Ya Nai for its hour-long beach break. This route also includes time at Koh Wai and Koh Klum, with two snorkel stops and a chance to swim ashore. It is the better fit if you want a shorter day with a clear balance between water time and beach time.

Koh Wai, Koh Lao Ya Nai, and Koh Klum

The 3-island route is not simply a cut-down version for people who dislike snorkeling. It is a sensible choice for families, first-timers, and anyone who wants to return to Koh Chang before late afternoon.

At Koh Wai, you get about 40 minutes for swimming and snorkeling. The schedule gives you enough time to see fish and coral without turning the outing into an exhausting endurance test.

Koh Lao Ya Nai provides the longer free-time stop. You can relax, swim, and enjoy the island scenery. This is where the shorter tour earns its place: you get a proper beach hour rather than racing through four names on a timetable.

Koh Klum completes the route, with another chance to snorkel and try open-sea fishing. Fishing is a simple extra rather than the main event, but children may enjoy the hands-on change from swimming.

The shorter tour starts later and reaches its first area sooner than the 4-island option. That means less time spent crossing open water and less exposure to seasickness. If you care most about seeing as many underwater sites as possible, choose four islands. If you want a pleasant half-day with fewer transfers, choose three.

Lunch, fruit, and the useful extras onboard

Lunch is freshly prepared on the boat and is chicken-based. It is a basic Thai meal, but it is more substantial than many people expect from an inexpensive boat tour. Water, coffee, fruit, and snacks are part of the package, with watermelon and pineapple served later in the day.

You can buy extra drinks and snacks onboard, including beer, soda, crisps, and noodles. Bring cash for these purchases and for the national park fee. The 4-island entrance fee is collected upfront, so do not arrive with only a card.

Vegetarian visitors should contact the operator at least one day before departure. A vegetarian meal can be arranged, and special dietary needs have been accommodated when advance notice was given. Do not wait until lunchtime and assume a replacement meal will appear.

The food is valuable because it saves you from buying lunch at an island stop. It also lets the crew serve everyone without extending the schedule. Expect practical boat food, not a restaurant meal, but the fresh fruit is a welcome finish after salt water and sun.

Underwater photographs and how to get yours

An underwater photographer is included, which is unusual at this price. The photographer takes candid shots on the boat and underwater images during snorkeling.

Here is the catch: make your interest known. Some passengers were not told clearly when the photographs would be taken and ended the day without pictures. Tell the guide or photographer before entering the water that you want to be included.

The photo service adds value for families and first-time snorkelers who may not have a waterproof camera. It also means you can focus on swimming instead of trying to hold a phone in a waterproof pouch.

Weather, safety, and who should skip it

Koh Chang weather can shift quickly, especially during the monsoon season. Rain does not automatically ruin the day, and the water may remain clear during wet weather, but you should bring sunscreen, sunglasses, a towel, swimwear, snacks, and cash.

The schedule can change with wind and sea conditions. If the crew decides conditions are unsafe, the tour can be canceled, rescheduled, or fully refunded. That flexibility matters because the 4-island crossing is long and exposed.

This is not suitable for children under two, pregnant women, wheelchair users, or people with back problems. The boat ride, pier access, and island transfers require a degree of mobility.

I would choose this trip for families with older children, couples, solo visitors, and first-time snorkelers who want an affordable introduction to Koh Chang’s islands. I would skip it if you need a private, quiet boat, guaranteed fins, advanced reef conditions, or a completely smooth ride.

Should you book this Koh Chang boat tour?

I would book the 4-island tour if snorkeling is your main reason for going. Three 40-minute water sessions around Koh Rang National Park, plus an hour on a beach, give you a full day without an inflated price.

Choose the 3-island tour if you prefer a shorter outing, want more time at a beach, or are worried about the long crossing and rough water. It still includes snorkeling, fishing, lunch, fruit, and the same general boat setup.

At $28, this is one of those tours where the value comes from the complete package rather than luxury. The boat may be crowded, the ride may roll, and the reefs may look similar from stop to stop. But the crew is attentive, the equipment is reported to be in good condition, the food is fresh, and the water time is generous. Tell the photographer you want pictures, bring cash, and arrive early. If that sounds like your kind of day, book it.
