Thailand is one of the easier long-haul countries to visit with children: hotels welcome families, food is mild if you ask, and health care in the cities is good. The real risks are heat, mosquitoes, the sea and the roads, and each of them can be managed with a little planning.
Thai people are generally warm towards children, and you will find that waiters, shopkeepers and strangers on the train pay them a lot of friendly attention. What makes a family trip harder is the climate and the distances. A route that suits two adults (night buses, three islands in a week, temples at midday) wears a child out quickly.
This guide covers the whole country: how to choose destinations, how to keep children healthy, how to move around safely, and what to do if something goes wrong. It summarizes what official health and safety sources say, but it is not medical advice; talk to your doctor or a travel clinic about your own children.

Where to go: destinations that suit families
The best family destinations combine short transfers, calm water and a choice of food and doctors nearby. Fewer, longer stays work better than a fast route: two or three bases in two weeks is plenty with small children.
| Destination | Why it suits families | Watch out for |
|---|---|---|
| Bangkok | Air-conditioned malls, parks, river boats, SEA LIFE aquarium in Siam Paragon, good hospitals | Heat, traffic, long walks between sights |
| Hua Hin | Long beach, quiet town, reachable by train or road from Bangkok, one of the driest beach areas | Wettest in September and October |
| Chiang Mai | Cooler evenings, cooking classes, nature close to town | Smoke haze from about January to April |
| Krabi (Ao Nang) and Koh Lanta | Wide beaches, many family resorts; Lanta is quiet and has roads and space | Rough sea and rip currents from May to October |
| Koh Samui | Direct flights, many family resorts, sheltered beaches | Rain from October to December; jellyfish July to October |
| Koh Samet | The closest beach island to Bangkok, short boat ride | Busy at weekends and on Thai holidays |
Bangkok works best in short doses: two or three days, with the morning outdoors and the afternoon in a mall, an aquarium or the hotel pool. Our Hua Hin guide covers a calm first beach stop after the capital. On the islands, Koh Lanta is the quieter choice on the Andaman side, and Koh Samet suits a short trip from Bangkok.
Pattaya has more theme parks and water parks than anywhere else in the country, but it also has nightlife areas you will want to avoid; our article on whether Pattaya is worth visiting for families goes through it in detail.
Places we would skip with young children: Haad Rin on Koh Phangan around the Full Moon Party, Phi Phi in the busiest months (no cars, steps and crowds with a stroller), and long minivan trips such as the mountain road to Pai, which makes many adults sick.
Heat and sun: plan the day around the hottest hours
Children overheat faster than adults and often do not say so until they are unwell. Bangkok's average daily maximum is above 32 °C in every month of the year and reaches about 36 °C in April, according to the Thai Meteorological Department's 1991–2020 averages.
Thai authorities use a four-level heat index scale. At the "warning" level (33 to 41.9 °C on the heat index), Bangkok's environment department advises reducing outdoor activity between 11:00 and 15:00; at "extreme danger" (52 °C and above), it advises avoiding outdoor activity altogether. Those are good rules for a family day: sights and beaches early and late, pool or nap in the middle.
Practical habits help more than anything you can buy: a wide-brimmed hat, a long-sleeved swim top, sunscreen from home if your child has sensitive skin, and water or an oral rehydration drink carried everywhere. Our guide to coping with heat and sun in Thailand explains the warning signs of heat exhaustion. If a child becomes confused, stops sweating or faints, call 1669.
Mosquitoes, dengue and malaria
Dengue is the mosquito-borne disease that matters most for families. It is spread by mosquitoes that bite during the day and is more common in towns and cities, according to the UK's TravelHealthPro. There is no routine dengue vaccine for children who travel; UK advice limits the vaccine mainly to people who have already had dengue. Prevention means avoiding bites: repellent suitable for your child's age, long, light clothing at dawn and dusk, and rooms with screens or air-conditioning.
Our pages on dengue fever in Thailand and on avoiding mosquito bites cover symptoms and repellents. Malaria is not a concern in the usual family destinations. The CDC limits its advice on preventive tablets to rural border provinces next to Myanmar, Cambodia and Malaysia, and it reports no transmission at all in Pattaya City or on the Krabi islands.
Vaccines and animal bites
Start with your child's routine vaccines. The CDC asks all international travelers to be fully vaccinated against measles, and recommends an early MMR dose for infants aged 6 to 11 months. It also recommends hepatitis A for unvaccinated travelers aged one and older, and says infants aged 6 to 11 months should be vaccinated too (a dose that does not count towards the routine series).
Our page on vaccinations for Thailand covers typhoid, Japanese encephalitis, rabies and the yellow fever certificate rule, and where the US and UK advice differ. Book the appointment four to eight weeks before you fly so that there is time for any course of doses.
Rabies is present in dogs in Thailand, and children are more likely than adults to stroke a street dog, a temple cat or a monkey. Teach them not to touch animals they do not know, and keep food out of sight around monkeys. After any bite or scratch, wash the wound well and see a doctor the same day. Our guide to animal bites and rabies shots explains what happens next.
Food and drink for children
Thai food is easier with children than its reputation suggests. Fried rice, grilled chicken, rice soup, noodle soups and fresh fruit are everywhere, and most cooks will leave out the chili if you ask. Our guide to ordering Thai food and spice levels has the phrase for "not spicy".
Give children bottled or filtered water, and use the same water for brushing teeth if they tend to swallow it. Busy stalls with high turnover and food cooked in front of you are the safer choice; our article on avoiding stomach trouble from street food has the details. Pack an oral rehydration solution from home or buy it at a Thai pharmacy, because diarrhea plus heat dehydrates small children quickly.
Formula, baby food and diapers are sold in supermarkets and convenience stores in the cities and tourist areas. If your child needs a particular brand or a special formula, bring enough for the whole trip; small islands have a limited choice.
Water safety: pools, beaches and jellyfish
Drowning is the most serious risk for children in Thailand, for local and visiting families alike. The Department of Disease Control counted 6,449 children under 15 drowned in Thailand in the ten years 2015 to 2024, about two a day. Most hotel pools have no lifeguard, and many beaches have none either.
- Pools: one adult watches the water at all times, without a phone. Check for a gate around the pool if you have a toddler.
- Beaches: swim only where there are lifeguards or calm water, and never when a red flag is up. On the Andaman coast (Phuket, Krabi, Khao Lak) the monsoon from May to October brings strong rip currents. Our guide to rip currents and beach flags explains what to do if a child is pulled out.
- Boats: ask for a child-size life jacket before you board, and do not take a speedboat in rough weather.
Vinegar, not fresh water, for a box jellyfish sting. The Department of Disease Control advises getting out of the water, calling 1669, keeping the child still without rubbing the skin, and pouring household vinegar on the sting for at least 30 seconds. Box jellyfish have been recorded off Samui, Phangan and Tao from July to October. Our page on jellyfish in Thailand covers where and when.
Getting around: car seats, taxis, trains and flights
Since 5 September 2022, Thailand's Road Traffic Act requires children up to six years old to ride in a child seat or a special children's seat, or with another means of protection set by the police; passengers up to 135 cm tall must be held by a seat belt. The fine is up to 2,000 baht. People riding in tuk-tuks and in vehicles that are not required to have belts are exempt.
In practice, ordinary taxis and most ride-hailing cars do not carry child seats. If your child needs one, bring a light travel seat from home or book a private transfer or rental car that supplies one, and confirm it in writing. Our sister site explains the rules in more depth in its guide to child car seats in Thailand.
Trains are often the most relaxed way to travel with children: they can walk around, there are toilets, and on the night trains a family can take a first-class compartment with a door that locks. Our guide to Thailand's night trains covers the berths. For long distances with small children, a short domestic flight usually beats a full day on a bus. Minivans are fast but cramped, with little room for a stroller or for stopping when someone feels sick.
Carry a light umbrella stroller or a baby carrier, not a big pram. Pavements in Thai cities are uneven and often blocked by stalls and steps, and boats and songthaews have no space for a large stroller. A carrier works on temple stairs and island piers where wheels do not.
If a child gets ill: hospitals, pharmacies and insurance
Bangkok, Chiang Mai, Phuket, Pattaya and Koh Samui have private hospitals of a high standard, and pharmacies are easy to find in every town. The UK Foreign Office warns that all hospitals require a guarantee of payment before treating patients, and that public hospitals outside Bangkok do not always meet Western standards. That makes travel insurance with medical cover essential for every family member; read our guide to travel insurance for Thailand before you buy.
Small islands have only clinics, and a serious case means a boat to the mainland, so check how far the nearest hospital is before choosing a remote island with a baby. Our guide to hospitals in Thailand explains how private and public hospitals work. Bring your child's regular medicines, with the prescription, in their original packaging.
Money matters: fees and discounts for children
Many sights and parks charge children less. Thailand's national parks charge foreign children half the adult fee: 50 baht in the cheapest category and 100 baht in the next (Department of National Parks fee structure from June 2022). Koh Samet, for example, is 200 baht for a foreign adult and 100 baht for a child. Private attractions set their own child prices, often by height rather than age, so carry a passport copy to prove an age if asked.
Frequently asked questions
Is Thailand safe for a family holiday?
Yes, for most families. The US rates Thailand at its lowest advisory level, Level 1, apart from some southern border provinces and areas near the Cambodian border. The practical risks for children are heat, mosquitoes, water and traffic, and you can reduce each of them with ordinary care.
Do children need a car seat in Thailand?
By law, children up to six must ride in a child seat or another means of protection approved by the police, and passengers up to 135 cm must wear a seat belt. Tuk-tuks are exempt. Taxis rarely supply child seats, so bring your own or book a car that has one.
What vaccines do children need for Thailand?
Routine childhood vaccines, including measles, should be up to date, and the CDC recommends hepatitis A from age one, with an early dose possible from six months. Others, such as typhoid or Japanese encephalitis, depend on the trip. Ask a travel clinic at least a month before you go, earlier if possible.
Which part of Thailand is best for families with small children?
Hua Hin, Koh Lanta, Koh Samui and Krabi's Ao Nang are good choices, with family resorts, calm beaches in season and short transfers. Choose the coast by month: the Andaman side from November to April, the Gulf side when the Andaman coast is in its monsoon.
Can I buy baby formula and diapers in Thailand?
Yes. Supermarkets, pharmacies and convenience stores in cities and tourist areas sell formula, baby food and diapers. If your child needs a specific brand or a special formula, bring enough for the whole trip, because small islands and rural towns have a limited choice.
