Ko Lanta: Koh Rok & Koh Haa Snorkelling Tour by Speedboat

Koh Haa and Koh Rok give you the best reason to leave Ko Lanta’s beaches for a day: clear water, coral reefs, and several chances to swim with fish. The twin islands of Koh Rok sit only 250 metres apart, and the white beach, monitor lizards, and hermit crabs add a pleasant land break to the sea time.

I like the three separate snorkelling stops, since conditions can vary from one reef to the next. I also like that lunch, fruit, drinks, equipment, a guide, and resort pickup are covered in the $59 price. The main caution is space: one account describes about 35 people packed onto a small speedboat, with little room for bags or drying off.

Key points to know

• Three snorkelling sessions: One at Koh Haa and two around Koh Rok give you more than one chance to find good visibility and fish.
• Koh Rok’s twin islands: Koh Rok Nok and Koh Rok Nai are separated by just 250 metres, creating a scenic snorkelling area between them.
• Guide Yaa earns special praise: If you are assigned Yaa, expect a guide who has made a strong impression for her care and handling of the day.
• A full eight-hour outing: Pickup runs from about 8:00 AM, with a return to your resort near 4:00 PM.
• Lunch and beach time included: You get about 90 minutes for food, swimming, a walk, and a look at the island wildlife.
• Boat comfort deserves attention: The ride can feel long, especially for anyone prone to seasickness or anyone expecting plenty of personal space.

Leaving Ko Lanta for Koh Haa and Koh Rok

The day begins with a resort pickup between 8:00 and 9:00 AM, depending on where you stay. Kantiang is first at 8:00 AM, followed by Klong Hin, Klong Nin, Klong Tob, Klong Khong, Long Beach, Klong Dao, Kawkwang, and Saladan. If you are staying in a less central part of Ko Lanta, your earlier pickup gives you a longer morning before the boat leaves.

The speedboat departs the pier at about 9:00 AM. From there, allow roughly an hour before the first snorkelling stop. That hour matters. The islands are not just offshore from Ko Lanta, so this is a proper day trip rather than a quick beach shuttle.

I would eat a light breakfast before pickup and keep your swimsuit on under your clothes. The boat ride can be lively, and changing onboard may be difficult if the boat is full. Keep your towel, sunscreen, sunglasses, and hat easy to reach, but protect phones and cameras from splashes.

The tour is described as lasting six minutes in one section, but the detailed schedule clearly shows a full-day outing, from morning pickup to a return around 4:00 PM. Plan for the full day on that basis.

Koh Haa at about 10:00 AM

Your first stop is Koh Haa, a group known here as the Five Islands. The boat reaches the area at about 10:00 AM, giving you around an hour to snorkel and enjoy the scenery above and below the surface.

The main appeal is the water clarity and the soft coral. You may see a range of fish moving through the reef, with the exact quality depending on weather, visibility, and the condition of the coral on the day. The sea can look wonderfully clear, but clear water does not always mean every coral patch is healthy.

That distinction is worth keeping in mind. One recent account praised the beaches and food but found much of the coral dead, while still seeing fish. Other accounts describe excellent visibility, a good range of fish, and a sea that felt like an aquarium. Both impressions can be true at different spots, or under different conditions.

The one-hour stop gives you enough time to get comfortable with the mask and snorkel before the main Koh Rok section. If you are not a confident swimmer, use the provided life jacket and stay close to the guide. Snorkel equipment and masks are included, along with accident insurance.

Koh Rok’s twin islands and coral channels

After Koh Haa, the boat heads to Koh Rok, the day’s main attraction. Koh Rok consists of Koh Rok Nok and Koh Rok Nai, with only 250 metres between the islands. That narrow separation creates a striking setting for snorkelling, with clear water, coral formations, anemones, and fish beneath the boat.

The first Koh Rok snorkelling session lasts about 40 minutes. You can expect a guided stop, time in the water, and views of the islands from the boat. The setting is a strong part of the experience. Even if the reef is less colourful than hoped, the bright water and two-island view make this more than a simple swim.

The fish life seems to be the reliable pleasure here. One highly positive account describes very clear water, good visibility, and a useful variety of fish. Another praised the snorkelling so highly that the water felt like an aquarium. Those comments make Koh Rok a good choice if seeing fish matters more to you than finding perfect coral at every metre.

The guide speaks English and Thai. A guide named Yaa receives especially warm praise for making the trip enjoyable. You cannot request her based on the supplied details, but it is useful to know that the quality of the guiding can add a lot to a boat day. A good guide helps you understand where to look, keeps the group together, and makes the stops feel less rushed.

Noon on a white beach

Around noon, you leave the water for lunch and free time on Koh Rok. You get about an hour and a half for eating, walking, swimming, relaxing, and taking in the island.

Lunch is included, along with soft drinks and seasonal fruit. The food has been well received, with one account specifically noting a good buffet lunch. It is not a restaurant meal, but it removes the need to carry a full picnic and gives you a proper pause between snorkelling sessions.

The beach is powdery and white, and the island wildlife adds a little character. Monitor lizards and hermit crabs are mentioned as regular sights. They are not trained attractions, so treat them as part of the island setting and give them room.

This break is important because the tour is active. Three snorkelling sessions, boat transfers, sun, and salt water can wear you down. Use the lunch stop to drink water, reapply sunscreen, and dry off as much as possible. If the boat is crowded, the beach may be the easiest place to sort your belongings and get comfortable again.

You also get time to decide how much activity you want. Swim near the beach, take a walk, or simply sit in the shade if you find it. The schedule is not just water to water, and that makes the day more manageable.

The final Koh Rok Nai snorkelling stop

At about 1:30 PM, you make one more snorkelling stop at Koh Rok Nai. This session lasts about 30 minutes. It is shorter than the earlier stops, but it gives you a final chance to see coral and fish after lunch.

By this point, you will know how your equipment fits and what kind of sea conditions to expect. That makes the last stop easier for many people. If you have already seen plenty, you can keep the session relaxed rather than treating it as a race to cover every metre.

Three water stops are a real advantage. If the first reef disappoints you, the day is not over. If the first two are excellent, the last stop lets you enjoy the sea without needing to make the whole trip worthwhile on its own.

The tradeoff is time spent aboard the speedboat. The schedule allows about an hour each way, but one account says the real journey felt closer to 90 minutes each direction. That longer estimate may reflect sea conditions, loading, or the actual route. Either way, prepare for a substantial ride.

The speedboat question: fast, but not always roomy

The speedboat is efficient for reaching Koh Haa and Koh Rok in one day. It also brings the main comfort risk. One low-rated account describes roughly 35 people on a very small boat, with passengers struggling to sit comfortably and bags resting on laps. The same account says there was no easy way to change clothes or dry off onboard.

I would take that warning seriously, especially if you dislike tight seating or become seasick. The boat may not be crowded every day, but the supplied information does not promise a small group or a particular boat size. Pack light and use a waterproof bag or dry sack for valuables.

Motion sickness is another practical concern. The route includes long open-water stretches, and one account reports people becoming ill onboard. If you are prone to seasickness, bring whatever remedy you normally use and sit where the crew advises. The tour is not suitable for pregnant women or people with mobility impairments.

The return trip leaves Koh Rok at about 3:00 PM, followed by the transfer back to your accommodation around 4:00 PM. After a full day in the sun, that final ride can feel longer than the morning run. Still, the boat is what makes the two-island route possible in a single day.

What the $59 price covers

At $59 per person, this is a reasonably complete day package. You are paying for round-trip resort transfers, the speedboat, a local guide, snorkel gear, a mask, a life jacket, lunch, soft drinks, seasonal fruit, and accident insurance.

The value improves if you are staying outside Saladan and would otherwise need to arrange transport to the pier. Pickup is included from accommodation on Ko Lanta, but you need to provide the resort address when booking. The pickup schedule is spread across the island, so your exact morning may vary.

The one extra charge is the national park fee: 400 baht for an adult and 200 baht for a child. Add that to the advertised price when comparing this trip with other island tours.

For a full day with three snorkelling sessions and food included, the cost is fair. I would not choose it solely for luxury or comfort. The value rests on reaching Koh Haa and Koh Rok without arranging several separate services, and on having more than one chance to find good water and fish.

Timing, closures, and what to pack

Bring sunglasses, a sun hat, swimwear, a towel, and sunscreen. I would also carry a waterproof pouch for your phone and cash, since the boat may offer little spare storage or dry seating.

Koh Ha is closed during the stated period from October 21 through November 30, 2024. If your travel date falls within a future seasonal closure, confirm the current operating dates before paying. The supplied information only gives that specific closure period, so it cannot confirm later park schedules.

The tour is offered with English and Thai guiding. Pickup is included, but the exact pickup time depends on your resort area. Kantiang pickups begin at 8:00 AM, while Saladan pickups are around 8:50 AM, with the speedboat leaving at 9:00 AM.

Free cancellation is available up to 24 hours before departure for a full refund, and you can reserve now and pay later. That helps if your island plans may shift, but it does not remove the need to check the national park dates and sea conditions.

Who will enjoy this day most

I would recommend this trip to you if you want a straightforward way to see two of Ko Lanta’s best-known snorkelling areas. It suits swimmers who like several water stops, families with children old enough to manage a snorkel and mask, and anyone who values included food and resort transfers.

It is also a good match if your priority is fish, clear water, and island scenery rather than a quiet private boat. The beach break helps, and the three snorkelling periods give the day useful variety.

I would hesitate if you need generous seating, easy changing space, or a small-group setting. The boat capacity may be the decisive issue. I would also think twice if you are pregnant, have mobility limits, or are very sensitive to long speedboat rides.

The coral quality may vary. Some people will find the fish and water make the trip worthwhile even when parts of the reef look damaged. If living coral is your main reason for booking, keep your expectations measured.

Should you book the Koh Rok and Koh Haa tour?

I would book this tour if you want a full, efficient snorkelling day at a moderate price and you can accept a basic speedboat setup. Koh Rok’s clear water, white beach, fish, and twin-island setting give the outing real appeal, while lunch and resort transport keep the planning simple.

I would not book it if comfort is your top concern. Before committing, ask the operator about expected group size and boat capacity for your date. If the answer is reassuring, the tour offers a good chance to see Koh Haa and Koh Rok in one day. If not, look for a smaller boat option, even at a higher price.
