Fun Diving Safari Day Trip From Koh Lanta – Certified Divers
Koh Lanta’s best underwater scenery lies offshore, and this full-day Scubafish trip gets you there without making you organize boats, tanks, food, or gear yourself. You spend the day on the water, with two underwater sessions at either the five islands of Koh Haa or Ko Bida Nok near Koh Phi Phi, depending on the season.
I like the small maximum group of 10 and the easy all-in setup: resort pickup, a full safety briefing, scuba equipment, snorkeling gear, breakfast, lunch, snacks, and drinks. I also like that a non-diving companion can snorkel while you go underwater, with the snorkeling guided too on some outings.
The main catch is the fixed seasonal plan. You cannot simply choose Koh Haa or Ko Bida Nok, and conditions can change the schedule. You also need a PADI Open Water certificate or equivalent, recent scuba experience within the last year, and enough time between the trip and any flight.

Key points to know before booking

- Koh Haa from October 15 to May 15: Two underwater sessions among five limestone islands, with time for snorkeling or relaxing afterward.
- Ko Bida Nok from May 16 to October 14: The low-season plan heads toward the Bida Islands near Koh Phi Phi.
- A genuine full-day outing: The trip begins around 8:00 a.m. and lasts about eight hours, including transport and time on the boat.
- Good support for mixed groups: Certified scuba participants can go underwater while companions snorkel, subject to the day’s arrangements.
- Small group size: The boat activity is capped at 10 people, useful if you prefer more personal attention.
- Bring your certification and recent logbook details: You must hold PADI Open Water or an equivalent qualification and have been underwater within the past year.
Why this Koh Lanta boat day works well

The appeal here is simple. You get a complete day at sea rather than a rushed add-on to a beach holiday. At $60, the price includes the costly and awkward parts of a scuba outing: tanks and other equipment, boat facilities, meals, drinks, and staff support.
That price is especially useful if you are not carrying your own equipment. Hiring scuba gear separately, arranging food, and finding transport to the pier can quickly make a seemingly cheap trip less convenient. Here, breakfast, lunch, fruit, pastries, bottled water, coffee, tea, and soft drinks are included.
The group limit also matters. A maximum of 10 participants gives the staff a better chance to keep track of everyone and adjust help to different comfort levels. You should still ask how many certified scuba participants will be in your group, since the maximum covers the whole activity, not necessarily one guide team.
This is not a private charter, so you should expect a shared boat and a schedule set by the operator. That is the tradeoff for the low price. You get a practical, social day rather than a custom trip built around your own preferred site.

Starting early from Kantiang Bay
The meeting point is Scubafish at 152/1 Moo 5, Kantiang Bay, on Koh Lanta Yai. The listed start time is 8:00 a.m., and pickup is offered from resorts on Koh Lanta. Confirm your pickup details after booking, since the exact collection time may depend on where you stay.
An early start makes sense. It gives the boat more time to reach offshore sites and leaves room for two underwater sessions, food, equipment changes, and the return journey. You should eat lightly before setting out, then use the included breakfast and snacks as needed during the morning.
The boat has a restroom, which is a small but valuable detail on an eight-hour sea trip. Drinks are available throughout the day, including water, coffee, tea, and soft drinks. Fresh seasonal fruit and pastries provide easy food between activities, while lunch is included as well.
Expect a practical boat day, not a luxury cruise. The information supplied does not specify the boat design, seating, shade, or travel time to each site, so ask about those points if you have motion sickness, mobility concerns, or strong preferences about sun exposure.
Koh Haa: the high-season choice

From October 15 through May 15, the trip heads to Koh Haa, a group of five islands. This is the more clearly defined route, and it offers two underwater sessions around a compact cluster of islands.
Koh Haa is known through the supplied trip details for clear water and a wide range of marine life. The area can offer close views of reef fish, moray eels, nudibranchs, lionfish, cuttlefish, groupers, and other small creatures, although sightings are never guaranteed. Conditions, visibility, and animal behavior change from one day to the next.
The five-island setting is part of the attraction. You get more than a single reef beside one rock. The group of islands creates a varied setting for underwater exploration and a scenic backdrop while you are on the boat. If you have a camera, the limestone formations and marine life give you plenty to watch for, but you should not book solely for one promised animal.
The trip includes two sessions underwater. Afterward, you can relax in the sun or snorkel, depending on time, conditions, and the boat schedule. Snorkeling gear is included, so a companion does not need to arrange a separate rental.
One useful point from the experiences associated with Scubafish is that snorkeling may be guided rather than left entirely on your own. That makes this plan a better fit for a mixed group in which one person is certified and another wants more structure in the water.
Ko Bida Nok during the low season

From May 16 through October 14, the route switches to Ko Bida Nok and the nearby Bida Islands near Koh Phi Phi. This seasonal change is important because you are not booking a free choice between the two areas. Your date determines the destination.
The Bida Islands offer another chance to see Thailand’s Andaman marine life from below. The trip description emphasizes clear water and varied wildlife, but it does not promise a particular visibility level or set of animals. Low-season weather can be less predictable, so build some flexibility into your Koh Lanta plans.
You still receive two underwater sessions, equipment, food, drinks, and time on the boat. The basic rhythm remains the same: travel offshore, receive site instructions, prepare with staff help, spend time underwater, return for food and a surface break, then continue to the second location or session.
The practical drawback is that weather may affect this route more sharply. The operator can cancel for poor conditions, offering another date or a full refund. That policy is reassuring, but it does not remove the inconvenience if this is your only available day.

What the staff support adds

A full briefing comes before you enter the water. This should cover the day’s plan, equipment, safety procedures, and how the group will operate at the sites. If you have not used your equipment recently, tell the staff early rather than trying to solve a problem once you are offshore.
Scubafish staff associated with these outings include Petur, who helps with organization, Pen, who has worked as a guide, and Roman, who handles underwater photography on some trips. Staff assignments can change, so treat these names as useful points of reference rather than a promise that one particular person will be on your boat.
The operation also prepares and changes tanks and equipment for participants, based on the details provided about the company’s wider service. That kind of hands-on support is valuable if you want to focus on the underwater time rather than carrying heavy gear around the pier.
Safety deserves more attention than sales language. You must hold PADI Open Water or an equivalent certificate, and you should have been underwater within the last year. The moderate fitness requirement is sensible: you need to manage a full day on a boat, handle scuba equipment, and cope with entries and exits in changing sea conditions.
Marine life and underwater expectations

The area can offer strong encounters with both large and tiny creatures. Specific animals connected with Scubafish outings include giant moray eels, nudibranchs, cuttlefish, lionfish, groupers, bannerfish, damsel fish, and reef fish. You might see some of these, but no responsible operator can guarantee them.
The variety is part of the pleasure. One moment you may be scanning a reef for a larger fish, then slowing down to find a small nudibranch or another camouflaged creature. A good guide can help you notice these details, especially if you usually swim past small life.
Coral conditions have changed over time. The supplied information notes that sites recovered after a serious bleaching event in 2010, with plenty of fish seen on later trips. That is useful context, but it also reminds you that reef health is not fixed. Treat the area gently, avoid contact with coral, and keep your buoyancy under control.
Underwater photography may be available to purchase. Roman is associated with excellent underwater photos on some outings, which can be worthwhile if you want a record without handling a camera yourself. Ask before departure how photos are priced and delivered.
Food, equipment, and comfort on the boat

The inclusive food list is unusually helpful for this price. You receive breakfast, lunch, snacks, fresh seasonal fruit, pastries, bottled water, coffee, tea, and soft drinks. Tell Scubafish about dietary requirements when you book rather than waiting until the morning.
Scuba equipment and snorkeling equipment are included. The information does not list individual sizes, brands, or specialty items, so contact the operator if you need prescription masks, unusual fin sizes, or other personal gear.
The boat restroom is another practical benefit. You are still spending much of the day at sea, so bring swimwear, sun protection, a towel, and any personal seasickness treatment you normally use. These items are not listed as included, and it is wiser to prepare for a long day outdoors.
There is also downtime. If you choose not to add a third underwater session, you can relax on the boat or snorkel. The trip description says an extra third location or experience may be available, so ask about the current supplement, timing, and conditions before counting on it.
Who should book this trip

This outing fits certified scuba participants who want a straightforward day from Koh Lanta. It is a good choice if you value included equipment, meals, pickup, and staff support more than a private itinerary.
It also suits couples and families with mixed interests. One person can take part in the scuba program while another snorkels, and the snorkeling may be guided. The small group limit is helpful for people who prefer not to be one name in a very large boatload.
You should think twice if you need a highly customized schedule, a guaranteed site, or a luxury vessel. The destination changes with the season, weather can cancel the day, and the available details do not promise private guiding or a particular boat style.
Children under 10 cannot take part because the minimum age is 10. Anyone who has not been underwater in the past year should not assume that a current certificate alone is enough. Ask Scubafish what refresher options are available before booking.
Is $60 good value?
For a full day, $60 is a strong value if you need rental equipment and would otherwise pay separately for transport and food. The package covers the major costs and adds the convenience of pickup from a Koh Lanta resort.
The value is less about luxury and more about removing hassle. You arrive at the meeting point, receive your briefing and equipment, spend the day offshore, and return to the same place. The end point is the meeting point, so arrange your evening plans with enough time for a late return.
Gratuities and souvenir photos cost extra. Tipping is not included, and you may purchase underwater photographs if available. Keep a little cash or another accepted payment method available, but confirm current arrangements with the operator.
The strong overall rating and full recommendation record point to a well-regarded operation, particularly for service, equipment care, safety attention, boat crew support, and guide-to-participant ratios. I would still judge the trip against your own priorities, since a good company cannot control visibility, weather, or wildlife sightings.
Booking advice and cancellation terms
Confirmation arrives within 48 hours, subject to availability. Do not leave this until the last morning if your holiday schedule is tight, especially during the busier high season.
You can cancel for a full refund up to 24 hours before the local start time. Changes or cancellations inside that 24-hour window are not accepted for a refund. If poor weather causes the operator to cancel, you can choose another date or receive a full refund. The same applies if the minimum number of participants is not reached.
Do not plan to fly within 48 hours after the trip. That interval is important after scuba activity, so place this outing early enough in your holiday rather than on the day before your flight.
Should you book the Koh Lanta scuba safari?
Book it if you are certified, recently active underwater, and want a well-organized day with the main costs bundled into one $60 price. Koh Haa is the appealing high-season route, while Ko Bida Nok gives the low-season program a clear alternative near Koh Phi Phi.
I would choose this trip for a small group that wants practical support, included meals, and the option to snorkel between sessions. I would skip it if your dates cannot tolerate weather changes, you need a private boat, or you are not currently comfortable using scuba equipment.
For the right person, this is a sensible way to reach Koh Lanta’s offshore sites without fuss. Just confirm the seasonal route, pickup time, dietary needs, and any equipment requirements before you pay.
