Planning Koh Lanta with young kids and all their gear

Small children change the parts of a Koh Lanta trip between places: the airport run, the car seat question, which boat day they can manage and moving a sleeping toddler around an island with few pavements. This guide covers those logistics, with the seat rules checked against Thai sources on 18 October 2026.

Child seat required (private cars)

age 6 and under

Maximum fine

2,000 THB

Krabi Airport to most hotels

about 2–3 hours

Car ferry crossing

about 15 min

Do kids need car seats in Thailand?

In a private car, yes: children aged six or under must use a child safety seat, or the driver must follow fallback rules. Taxis and public transport were reported as exempt.

The rule is Section 123 of the Land Traffic Act, rewritten by the Land Traffic Act (No. 13) of 2022, published in the Royal Gazette on 7 May 2022 (Sanook) and in force from 5 September 2022 (Pattaya Mail). A Royal Thai Police notification, gazetted on 16 February 2023, set the detail (The Standard). It took effect on 17 August 2023, as The Standard and PPTV reported from the government’s announcement.

What the rules say, as reported:

• Seat types. Rear-facing or forward-facing child seats, or a booster cushion without a backrest.
• No seat available. The driver must go slowly and keep left. The child rides in a rear seat (in a pickup, in the front cab, never in the open back), with a carer beside them or a lap belt.
• Taller children. Section 123 also covers passengers up to 135 cm, who must be belted in or protected another way. That is booster territory for most children.
• Exemptions. The Act excludes three-wheelers and vehicles not required to have seatbelts (Sanook). The 2023 announcement said vehicles carrying passengers for hire, such as taxis, and public transport are exempt (The Standard, PPTV).
• Penalty. A fine of up to 2,000 THB.

We found no reliable report of how the rule is enforced, or any guidance on seats certified abroad.

Koh Lanta taxi with a car seat, transfers and rental cars

The law matters most when you drive yourself. A car you rent and drive yourself is not a vehicle for hire, so expect the seat rule to apply to you as the driver. Read whether renting a car on Koh Lanta is worth it for the licence and insurance side, and ask about a seat when you request car rental.

Taxis and transfers with a driver count as vehicles for hire, so a seat is not legally required, but it is still the safest way to carry a toddler for two hours on Highway 4. Lanta’s tuk-tuks are motorbikes with a covered sidecar, and a pickup taxi’s back is a bench. Neither can hold a seat securely, so for a baby ask for a private car.

Your arrival day from Krabi Airport with small children

Plan for two to three hours from landing to your hotel, and longer if the car ferry queue builds. The key to a good day is starting the car part fed, changed and ready to nap.

1. Arrivals hall Bags, plus immigration on an international flight. Use the toilets and change nappies before you go out to the car. 30–60+ min
2. Fit the seat If you brought one, fit it at the car before you load bags. about 10 min
3. Drive to Ban Hua Hin pier About 65 km to the pier (in Krabi, not Hua Hin town). This is the best nap window. Ask for a stop at a fuel station if anyone needs one. 1–1.5 hr
4. Ferry queue and crossing Queues range from none to hours in high season; the crossing itself is short. Keep water and snacks in the car, not in the boot. 15 min plus any queue
5. Koh Lanta Noi to your hotel About 10 km over the Siri Lanta bridge to Saladan, then south. Khlong Toab (Klong Toab) is about 20 minutes further. 20–60 min

Krabi Airport to Koh Lanta step by step covers the journey in full, and our car ferry guide the queues. After a late landing, a night near the airport is often kinder to children. To book the ride, see the Krabi Airport to Koh Lanta transfer.

What to bring and what to ask for

Bring anything your child depends on that would be hard to replace, and ask about the rest before you book.

Item	Bring from home	Ask before you book
Car seat or booster	Yes, if under six or under 135 cm	Whether a seat can be arranged
Pushchair	A light folding one	Luggage space in the car
Baby or toddler carrier	Yes	Not needed
Formula and nappies	All specific formula, a few days of nappies	Not needed
Child life jacket	Worth it for under-threes	Sizes on the boat
Sun gear	Hats, rash vests, SPF 30+	Shade on the boat
Snorkel mask	A child’s mask that fits	Child sizes on board
Medicines	Prescriptions, fever medicine, rehydration salts	Not needed

Pushchair or carrier on Koh Lanta with a toddler

Bring both if you can, but expect to use the carrier more. Wheels sink in soft sand, and much of the main road has rough verges instead of pavements. A pushchair earns its place at the airport, on resort paths and in Old Town. A carrier handles beach lanes, steps down to the sand and boat boarding, where you need both hands.

Boat trips from Koh Lanta with kids

Choose the shortest crossings and a calm day. The 4 Islands hops between nearby islands with beach stops, while Koh Rok and Phi Phi involve longer runs over open water. Compare all three on our Koh Lanta boat tours page.

Longtail or speedboat

A speedboat cuts the time aboard but bounces in a swell. A longtail is slower and loud, so ear defenders help babies, but it suits short hops.

Life jackets and snorkelling

TAT said in 2016 that all boat passengers must wear life jackets at all times on board, and in October 2026 Pattaya’s Tourist Police applied that to “adults and children alike”. Ask whether a jacket in your child’s size will be on board, or bring one. For snorkelling, little ones do best at shallow beach stops, in a life jacket, with a mask that fits.

Emerald Cave and kayaking

The Emerald Cave on Koh Mook is entered through a dark passage in the water, which not every small child enjoys. Read before you enter the Emerald Cave and decide in advance whether you will skip it. We also arrange kayaking at the Tung Yee Peng mangroves and the Koh Talabeng sea caves; ask us about minimum ages before you book.

Heat, sun, sea and the rainy months

Shade and water matter more than any itinerary. The NHS advises keeping babies under six months out of direct strong sunlight, shade from 11:00 to 15:00, at least SPF 30 and reapplying straight after swimming. Thailand’s sun is stronger than the UK’s, so treat that as a minimum.

The FCDO warns that people have drowned in riptides and tells swimmers to obey red flags. It says jellyfish come close to shore, especially in the rainy season from May to October, when seas are rougher. Keep a spare day for any boat trip then. It also lists dengue as a risk, so ask a pharmacist for a repellent suited to your child’s age.

Koh Lanta with a baby, hospital and supplies

Everyday needs are covered on the island; specific products are less certain.

• Koh Lanta Hospital. The public hospital, listed by the Social Security Office at Moo 1, Ban Hua Laem, Ko Lanta Yai. OpenStreetMap places it about 1.5 km south of Old Town, roughly 11 km (17 minutes) by road from Khlong Toab. Map apps also show a health centre in Saladan; for the hospital itself, search for Koh Lanta Hospital (โรงพยาบาลเกาะลันตา).
• Emergencies and insurance. The FCDO gives 1669 for an ambulance and says hospitals require a guarantee of payment before treatment. Check that your insurance covers medical evacuation.
• Clinics and pharmacies. OpenStreetMap shows private clinics and more than a dozen pharmacies, mostly between Saladan and Khlong Toab, plus one in Old Town.
• Shops. The same map lists 13 7-Eleven stores and two Lotus’s go fresh supermarkets. Bring all of any specific formula; brands and nappy sizes on the shelf vary.

What to send us before you travel

One message lets us plan around your children. Send:

1. Your flight number, landing time and hotel.
2. The number of adults and children, the children’s ages, and roughly their height and weight.
3. Whether you are bringing a car seat or booster, and which type.
4. Your bags, pushchair and any other bulky gear.
5. Any boat day or kayaking you are considering, and each child’s confidence in the water.

Ask us about child seats, life jacket sizes and age limits for trips and kayaking, and we will reply with what is possible, the price and availability. Start with a private transfer for arrival day.
