Scuba Diving Day Trip at Koh Chang – 2 Dives

The main draw is the choice between HTMS Chang, Thailand’s largest shipwreck, and the calmer reefs of Koh Rang National Park. Both offer a full day on the water, with colorful coral, tropical fish, and the chance of spotting unusual creatures such as nudibranchs or, occasionally, whale sharks.

I like the small maximum group of four and the care built into the day, from equipment setup to hotel transfers. I also like that guides such as Steve have helped rusty certified divers regain confidence before getting in the water. The main consideration is that the exact site depends on the day, and the advertised two underwater sessions can differ from the more expansive descriptions of three stops or additional reef descents.

Key points to know

• HTMS Chang offers a memorable wreck setting: The ship’s towering structure is suitable for certified divers of different levels, though one guest found an advanced open water qualification useful for seeing more of it.
• Koh Rang is the gentler choice: Calm water and shallow reefs make the national park appealing if you prefer coral gardens over a large wreck.
• The group limit is four people: This gives the guide more time to help with equipment, buoyancy, and a refresher before the first descent.
• The day includes the practical extras: Hotel pickup and return, equipment, buffet lunch, drinks, and light refreshments are covered.
• Guides receive strong praise for personal care: Oscar, Steve, Max, Chang, and boatmaster Oscar are named in the feedback, with special notice given to Steve’s patient refresher help.
• Check the final plan carefully: The package is promoted as two underwater sessions, but some schedules include three stops or an optional extra session for 1,000 baht.

Choosing between a Thai warship and protected reefs

This is not a quick splash-and-go outing. You leave around 8:00 a.m., spend roughly eight hours with BB Divers, and return to the same meeting point at the end of the day.

Your central choice is simple. The HTMS Chang gives you a large man-made structure to explore, with marine life gathering around the wreck. Koh Rang National Park offers calmer water, shallower coral areas, and several locations for underwater viewing and snorkeling. The operator decides the final route according to the day’s plan, so you should not book this expecting a guaranteed choice of site.

I like that the two options suit different moods. The wreck has drama and scale. The national park is likely the better match if you want an easier pace and colorful coral rather than a ship’s metal corridors and hull.

The phrase two dives needs a little unpacking. The package is sold as a two-dive day trip, but the description of the HTMS Chang route refers to the wreck plus two reef sessions. The Koh Rang plan refers to three different dive and snorkel stops. Some people also add another underwater session for 1,000 baht. Ask BB Divers what your specific departure includes before you pay, especially if the number of descents is a major reason for booking.

What the HTMS Chang wreck adds to the day

The HTMS Chang is the star attraction for certified divers who enjoy wrecks. It is described as the largest shipwreck in Thailand, and its size gives the experience more character than a simple reef visit. You can look along the ship’s large structure while fish and coral occupy the surrounding water.

The wreck is suitable for divers of all levels, according to the operator, but that does not mean every part will suit every certification or comfort level. One person who visited the wreck reported a depth of about 18 metres above it and suggested an advanced open water qualification for the wreck experience. That is useful practical advice: ask about the planned depth and route if you hold only an entry-level certification or have not been underwater for a while.

You do not need to arrive as a technical wreck specialist. The professional guide handles the site briefing and leads the group, while the small party size allows closer attention. Still, you should be honest about your experience, recent activity, and comfort in open water. A big shipwreck can feel more demanding than a shallow reef, even when the operator accepts divers of different levels.

The ship is also a good reason to bring a camera if you already have one. I would not buy special equipment just for this trip, since the necessary gear is included, but a camera can help you remember the shape of the wreck and the marine life around it.

Why Koh Rang National Park may suit you better

Koh Rang National Park is the softer alternative. The area is known for calm water, shallow reefs, colorful coral, tropical fish, and attractive underwater scenery. The plan includes three different dive and snorkel stops, though the exact number of underwater sessions should be confirmed because the main package is described as two dives.

This option makes sense if you want variety without making the wreck the center of the day. It also suits a family or group with mixed confidence, provided each participant meets the certification requirements for the scuba portions. One family used the service with three less experienced members, and Steve helped them feel comfortable with the equipment and procedures.

The national park option is not merely a backup for bad conditions. It has its own appeal. Protected water and shallow reefs can give you more time to look closely at coral, small fish, and tiny creatures such as nudibranchs. If your pleasure comes from finding small life rather than seeing a large ship, Koh Rang may be the stronger choice.

Snorkeling is included in the Koh Rang plan, but you should not assume every person will receive the same mix of scuba and snorkeling. Ask the crew how the day will be arranged when you check in.

A small boat group changes the experience

The maximum group is four travelers. That is one of the strongest features of this trip because underwater activities become easier when the guide is not managing a large crowd.

With four people, you can expect more direct help with equipment and a clearer briefing before entering the water. You are also less likely to spend the whole session trying to keep sight of a distant guide or waiting for a large group to assemble. The feedback repeatedly points to friendly staff, careful assistance, and a well-run boat operation.

The named guides include Oscar, Steve, Max, and Chang. Boatmaster Oscar is singled out for leading good site visits and helping participants throughout the day. Steve receives particular praise for supporting someone who had not been underwater for some time, refreshing the key steps before the first session rather than treating certification as proof that no help was needed.

That personal attention matters most if you are certified but rusty. You still need to provide evidence of certification, but a card alone does not tell the crew how comfortable you feel. Tell the team if your last scuba trip was a long time ago. The staff can then give you more useful support before you begin.

What the eight-hour schedule feels like

The day starts at 8:00 a.m. at BB Divers, the PADI 5 Star Dive Center at 16/2 Moo 1, Tambon Koh Chang Tai. Free hotel pickup and return are included, which is helpful if you are staying away from the center or do not want to arrange a taxi before sunrise.

Once you arrive, expect the practical preparation: certification checks, equipment use, a briefing, and the boat trip to the chosen sites. The exact sequence is not provided, so I would treat the advertised schedule as a full-day framework rather than a minute-by-minute plan.

The first underwater session may be the wreck or a reef site. Afterward, you return to the boat for food and a break before the next session. A buffet lunch is included, along with drinks and light refreshments. Free drinks sound minor, but they matter on a sunny day at sea, particularly when your morning includes repeated activity and time on a warm boat.

Some descriptions refer to an additional reef session after the HTMS Chang wreck, while the main product title specifies two dives. The safest approach is to ask at the center whether your booking covers two or three underwater sessions and what extra charges apply. Additional dives may be available for 1,000 baht.

The day ends back at BB Divers. You are not left arranging your own return from a remote pier, and the included hotel drop-off removes one more job after a tiring day.

Equipment, lunch, and the value of the package

At $130.39 per person, this is not a budget beach activity. The price needs to be judged as a full-day scuba package rather than a single boat outing.

You receive equipment, a professional guide, all activities listed for the trip, hotel pickup and return, lunch, drinks, snacks, and the boat-based experience. The national park fee is not included, so add that cost to your planning. The optional extra session also costs more.

I like the way the package bundles the parts that can quietly inflate a day on the water. You do not need to rent basic equipment separately, bring your own lunch, buy drinks during the trip, or arrange two local transfers. The maximum of four also gives the price more meaning if you value personal guidance.

The package becomes better value if you want both a wreck and reef settings, or if you are traveling without your own equipment. It is less compelling if you only want a quick shallow swim or already have access to a boat and full scuba kit.

Food is a buffet lunch rather than a restaurant meal, so keep expectations sensible. It is there to refuel between sessions and make the day easier, not to turn the boat into a fine-dining venue. You can advise the operator of dietary requirements when booking, which is important if you need a specific meal.

How to prepare if you have not been underwater lately

Certification is required for every scuba participant. Bring proof of your qualification, and be direct about how recently you last used your skills.

If you feel rusty, say so before the boat leaves. Steve has helped people refresh the basics and feel ready again, but you should still make your own decision about comfort and ability. This is a guided trip, not a replacement for a formal refresher course.

A few practical questions are worth asking at the center:

• Is the plan HTMS Chang or Koh Rang?
• How many underwater sessions are included on your assigned route?
• What depth and route are planned for the wreck?
• Is the national park fee payable separately on the day?
• Can you add another session for 1,000 baht?
• What food is available if you have dietary restrictions?

You should also expect to spend much of the day on a boat in the sun. Use the included drinks, take the schedule at a steady pace, and tell the crew promptly if you feel uncomfortable. The staff can only help if you speak up.

What the strongest service details tell you

The most consistent positive detail is not a particular fish or coral formation. It is the staff’s care.

The operation receives praise for well-maintained equipment, organized schedules, friendly boat support, and patient instruction. One person highlighted the office staff, Mr. Cho, and Steve. Another described a smooth Christmas-period outing with the instructors and boat crew working well together. A separate account praised Oscar for choosing good sites and helping throughout the day.

That matters because scuba days can go wrong through small failures: unclear equipment allocation, poor timing, weak briefings, or a guide who overlooks a nervous participant. The information available here points to a company that pays attention to those basic tasks.

There is also a useful reminder not to expect perfection from a day at sea. One person could not finish the final part of the day after something got into an eye and needed treatment. That does not point to a pattern of poor care, but it does show that conditions and minor mishaps can affect the schedule. Good insurance and sensible personal limits remain important.

Who should book this Koh Chang trip

I would put this trip high on the list for a certified scuba diver who wants a simple full-day plan with equipment, food, transfers, and a very small group.

It suits you especially well if:

• You want to see the HTMS Chang wreck.
• You prefer a guided day rather than arranging a boat yourself.
• You have not been underwater recently and want patient support.
• You value a small group of no more than four.
• You want coral and reef options at Koh Rang National Park.
• You need hotel pickup and return.
• You want lunch, snacks, and drinks included.

I would think twice if you are not certified, since certification is required for the scuba portion. I would also hesitate if you need a guaranteed wreck visit, a fixed number of three underwater sessions, or a tightly timed afternoon. The site and exact program can vary.

The 99 percent recommendation rate and 4.9 rating from 150 reviews point to a very strong record, especially for service and organization. Still, the price is best justified by the small group and bundled services, not by assuming that every trip will produce a whale shark sighting. Whale sharks are a possibility, not a promise.

Should you book it?

Book this if you are certified, want a full day on the water, and value close support more than the lowest possible price. The choice between HTMS Chang and Koh Rang gives you a useful contrast: a large historic wreck or calmer protected reefs.

Before confirming, ask BB Divers to spell out the route, number of underwater sessions, national park fee, and any extra charges. If those details match what you want, the combination of careful staff, small numbers, included gear, food, drinks, and hotel transfers makes this one of Koh Chang’s more practical scuba choices.

Free cancellation is available up to 24 hours before the start time. Changes or cancellations made inside that window are not accepted for a refund.
