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

Clear water, coral reefs, and a long day at sea.

This tour takes you from Ko Lanta to two of Thailand’s finest snorkeling areas, Koh Haa and Koh Rok, by speedboat. I love the clear water and good fish sightings, and I like that the day includes several separate snorkeling stops rather than one rushed swim. The white beach at Koh Rok, a buffet-style lunch, fruit, and drinks add useful comfort between swims.

The main concern is the boat ride and group size. One recent booking described about 35 people squeezed into a small speedboat, with little room for bags or changing after snorkeling. The ride can also feel rough, and the listed schedule suggests about 90 minutes each way in some conditions, even though the planned timetable presents the transfer as closer to one hour.

Key points to know before booking

• Koh Haa comes first: You reach the Five Islands area at about 10:00 a.m. for the day’s first coral and fish stop.
• Koh Rok offers three water sessions: Two reef stops are paired with beach time, lunch, swimming, and a walk onshore.
• The full day runs roughly 8:00 a.m. to 4:00 p.m.: The advertised duration of six minutes is clearly a display error, not the actual length of the excursion.
• Guide Yaa earns special praise: If she is leading your boat, expect a guide who has received especially warm feedback for her service.
• National park fees cost extra: Adults pay 400 baht and children pay 200 baht.
• Boat comfort matters: Ask about expected group size and prepare for a crowded ride if the boat is full.

What this Ko Lanta boat trip is really like

The day begins with a resort pickup on Ko Lanta between 8:00 and 9:00 a.m. Exact timing depends on where you stay. Kantiang is first at 8:00, followed by Klong Hin at 8:10, Klong Nin and Klong Tob at about 8:20, Klong Khong, Long Beach, and Klong Dao at about 8:30, Kaw Kwang at 8:40, and Saladan at 8:50.

That spread matters. If you stay near Kantiang, your morning starts earlier, but you may spend less time collecting other passengers. If you stay near Saladan, you get a little more time before pickup but may sit through several resort stops. Keep your phone available, have your bag ready, and confirm that the operator has your resort address.

The speedboat leaves the pier at about 9:00 a.m. From there, the schedule points to roughly an hour on the water before Koh Haa. In practice, the transfer may take longer. One account described about 90 minutes each way, and several people became seasick during a crowded return journey. If you are sensitive to motion, bring any medicine you normally use and choose a seat with care.

The operator supplies a life jacket, but you should still bring a towel, swimsuit, sunscreen, sunglasses, and a hat. You will want a dry layer for the ride back, although space to change on the boat may be limited.

Koh Haa at 10:00 a.m. brings the first reef

Koh Haa means Five Islands, a group of limestone islands surrounded by clear water. The first snorkeling stop is scheduled for about 10:00 a.m., after the boat ride from Ko Lanta.

This is a good opening stop because you can get comfortable in the water before the busier Koh Rok portion of the day. The scenery works both above and below the surface. You may see soft corals, reef fish, and other sea life in the shallow water, with the islands creating a dramatic backdrop.

The strongest praise for this tour centers on water clarity, fish variety, and visibility. One booking described the experience as similar to swimming through an aquarium, while another specifically praised the clear water and range of fish. That is the right reason to book this trip: you are paying for access to offshore snorkeling sites that are more remote than Ko Lanta’s beaches.

Still, coral quality can vary. One account found much of the coral dead but still saw plenty of fish. That is a useful warning. Do not expect every reef to look perfect or every stop to offer the same conditions. Sun, tides, recent weather, and water movement all affect what you see.

The first session lasts about an hour. Your guide speaks English and Thai and should help explain where to swim and how to use the mask and snorkel. You receive the equipment, but check the mask seal before entering the water. A leaking mask can turn a pleasant swim into a constant battle with fog and water.

Koh Rok’s twin islands and its best swimming water

Around 11:00 a.m., the boat continues to Koh Rok. Koh Rok is formed by two islands, Koh Rok Nok and Koh Rok Nai, separated by only about 250 meters. The water between them is a major reason this area attracts snorkelers.

The first Koh Rok session is scheduled for about 40 minutes and includes sightseeing from the boat. Here, you can expect coral reef, anemones, and a broad mix of fish. The water is described as especially clear, making this the part of the day most likely to produce the classic tropical snorkeling experience shown in brochures.

I would not treat the timing as rigid. Boats need to anchor, people need to enter and leave the water, and sea conditions can alter the plan. Your actual time in the water may be shorter or longer than the printed schedule.

Koh Rok is part of a national park, so the fee is not included in the tour price. Budget 400 baht for an adult or 200 baht for a child. This is a significant extra cost when you are comparing the total price, especially for a family.

Lunch and beach time on Koh Rok

At about noon, you come ashore for lunch and a longer break. The meal includes lunch, soft drinks, and seasonal fruit. The food has received positive feedback, with one person specifically calling it a nice buffet lunch.

This pause is important. A full morning of boat travel and snorkeling can leave you tired, sunburned, and hungry. The meal gives you time to sit down rather than spending the entire day moving from one reef to another.

Koh Rok’s beach is made of fine white sand, and the island also offers a chance to walk, swim, and take in the scenery without a mask over your face. Monitor lizards and hermit crabs are part of the onshore setting. They are not a petting-zoo attraction, so enjoy them from a respectful distance and do not feed them.

The beach stop lasts about 90 minutes. That is enough time for lunch and a walk, but not an afternoon of complete solitude. Boats may share the area, and the amount of quiet depends on the day’s crowds.

Smoking during the lunch break was a complaint in one account. If you want a smoke-free setting, keep that possibility in mind. It is a small detail, but it can affect your enjoyment of a beach meal.

The final Koh Rok snorkeling stop at 1:30 p.m.

The last water stop is scheduled for Koh Rok Nai at about 1:30 p.m. This gives you one more chance to see coral, anemones, and fish after the beach break.

Three separate snorkeling sessions are a real benefit. If the first stop has poor visibility or the second feels crowded, you still have another opportunity. You may also notice different sea life at each site, though the exact conditions cannot be promised.

You should pace yourself. The tropical sun is strong, and the repeated pattern of swim, boat, swim, beach, and swim can wear you down. Drink the supplied soft drinks, use sunscreen repeatedly, and keep your hat and towel handy.

The tour is not suitable for pregnant women or people with mobility impairments. The speedboat, water entry, beach stop, and lack of easy changing space all make this a physically demanding day. The operator also includes accident insurance, but that does not remove the need to judge your own comfort in open water.

The ride back can decide the whole day

The boat leaves Koh Rok at about 3:00 p.m. and returns to Ko Lanta around 4:00 p.m. The timetable looks tidy, but sea conditions and the number of passengers can change the experience.

This is where the biggest practical criticism appears. A full speedboat with about 35 people can feel cramped, particularly after swimming. There may be little room for bags, and you may need to keep personal items on your lap. Changing clothes or drying off on board may be difficult.

That is not a minor issue on a trip with long transfers. If the sea is rough, a cramped boat makes motion sickness harder to manage because you cannot move around freely. Some people also reported vomiting during the ride. Bring water, motion sickness supplies, and a plastic bag for wet clothing.

Before booking, ask the provider how many people they expect on your departure. The experience can be excellent with a manageable load and uncomfortable when the boat is packed. The stated price of $59 per person is fair if you value the transport, guide, equipment, lunch, drinks, fruit, and access to both island groups. It becomes less attractive if the boat is overloaded or if long transfers leave you with less time in the water than expected.

What the $59 price includes

At $59 per person, the package covers several costs that can add up on their own:

• Resort pickup and return on Ko Lanta
• Speedboat transport
• English and Thai speaking local guide
• Snorkel mask and equipment
• Life jacket
• Lunch
• Soft drinks and seasonal fruit
• Accident insurance

The national park charge is separate. An adult should add 400 baht, and a child should add 200 baht. The price also does not promise a private boat or a small group, so do not compare it with a private charter without checking what kind of day you want.

The tour offers free cancellation up to 24 hours before departure and allows you to reserve without paying immediately. That flexibility helps if your Ko Lanta plans depend on weather, but the key decision is still the boat capacity and sea conditions.

Who will enjoy this tour most

I would recommend this trip to you if your main goal is seeing several offshore reefs in one day. It suits confident swimmers, people who want a structured schedule, and visitors who prefer having transport, equipment, food, and a guide arranged in one booking.

It is also a good choice if you want both water time and a proper beach stop. The combination of Koh Haa’s first reef, Koh Rok’s clear water, a white sand beach, and three snorkeling sessions gives the day useful variety.

You may want a different plan if you dislike speedboats, get seasick easily, need lots of personal space, or prefer a quiet beach outing. The distance from Ko Lanta is not trivial, and a crowded boat can change the mood quickly.

Guide Yaa is worth requesting if she is available. Her guidance received particularly strong praise, and a good guide matters when you are dealing with equipment, open water, timing, and a large group.

Final verdict: book it with two checks

I would book this tour for the reef access, clear water, fish, multiple snorkeling stops, and the excellent Koh Rok beach break. The $59 base price offers solid value once lunch, transfers, equipment, drinks, and a guide are counted.

I would only book after confirming two points: the expected number of people on the speedboat and the current condition of Koh Haa. Koh Haa closes from October 21 through November 30, 2024, according to the supplied information, so check the operating date rather than assuming every departure includes that stop.

Book it if you want a full, active day and can accept a long boat ride. Skip it if comfort, quiet, or flexible time matters more than reaching distant reefs.
