Koh Samui with Kids: Family-Friendly Days Out by Age Group

Travelling to Koh Samui with kids is fairly straightforward. The island is compact and has its own airport, and calm-water boat days, waterfalls, temples and elephants are all within about an hour’s drive. A three-year-old and a teenager want different things, though, so the days out below are sorted by age group, followed by a sample plan and the safety points parents ask us about most.

Before you go: planning basics

Choose your season. Koh Samui’s weather doesn’t follow the same pattern as Phuket and the Andaman coast. Its wettest stretch usually runs from around mid-October to early December, under the northeast monsoon. The months either side are generally more reliable for beach and boat days.

Base yourselves sensibly. Chaweng is the busiest area. Bophut, Maenam and Choeng Mon along the north coast are generally quieter. Wherever you stay, check the hotel’s pool, shade and kids’ club, because on hot afternoons those matter as much as the beach.

Pace the days. Don’t put two full-day outings back to back. Follow each one with a pool or beach day. Half-day trips like the elephant sanctuary fit well around naps.

Days out by age group

Toddlers and under-5s

At this age, keep trips short, with shade and a toilet close by.

• Samui Elephant Kingdom (half day). The trip takes about 3 hours and includes hotel pickup, lunch and soft drinks. You watch the elephants from a raised skywalk and from behind barriers, with no open contact. Very young children may need carrying on the walkways, and they need a hand on them at all times. Children aged 5–11 pay ฿1,700, and under-5s are free.
• A gentle waterfall stop. Namuang Waterfall 1 is a short walk from the car park and has a pool at the base. The rocks are slippery, so carry little ones over wet stones.
• Big Buddha (Wat Phra Yai). The 12-metre golden Buddha on Koh Faan, built in 1972, is a short, easy stop. Cover shoulders and knees, and take shoes off where signs ask.
• Fisherman’s Village, Bophut. The old shophouse street makes an easy evening walk. The walking street market, usually on Friday evenings, gets busy, so bring a carrier rather than a pram.

Catamaran with under-5s? Under-5s travel free on our 1-Day Catamaran, and the boat has a toilet onboard. It’s a full day (hotel pickup 9:00–9:40 AM, back at the hotel around 4:30 PM), so it works for toddlers who can nap on the go. Life jackets are included and child sizes are on board, so don’t pack one from home.

Ages 5–11

This is the age the island suits best. Children are old enough to join in and still young enough to be amazed.

• Samui Elephant Kingdom. Children get stuck into making “Powerball” elephant food, which most of them enjoy. Then they feed the elephants from the 400-metre skywalk and watch them mud-bathe on their own. The sanctuary’s official site says there is no riding and no bathing. For the full schedule, read what to expect at Samui Elephant Kingdom.
• 1-Day Catamaran. On board there’s a water slide into the sea, a springboard, a floating sea pool, kayaks, paddleboards and a banana boat, all included in the price. You see the Five Islands from the boat, with swiftlets nesting in the cliffs. Then there’s snorkelling at Koh Tan and a stop at Koh Madsum, better known as Pig Island. Lunch onboard includes dishes most children will eat, such as spaghetti with tomato sauce, fried chicken, spring rolls, rice and fruit.
• Explore the Real Samui 4×4 Island Safari. A full day around the island by 4×4 pickup truck, from 9:30 AM to about 4:30 PM. Children can make traditional khanom ko sweets in Chaweng village, watch a rubber tapping demonstration and swim at Namuang Waterfall 1. Be aware that one stop, Wat Sawang Arom, displays a mummified monk. Some children find this fascinating and others find it unsettling, so tell them about it beforehand.

Tweens and teens

Older children usually want more action and more independence.

• Catamaran water sports. Paddleboarding, kayaking, the floating sea pool and snorkelling at Koh Tan give teens something active to do. A Thai massage on board gives parents a break, and it’s all included in the price.
• Island 4×4 day. The Explore the Real Samui 4×4 Island Safari includes Wat Teepangkorn, a temple at the top of a mountain, and lunch with a view. It gets you into the island’s green interior, away from the beaches.
• Elephant Kingdom. For a teen interested in animals, the questions in our ethical elephant sanctuary guide make a good discussion before the visit.

Safety notes for parents

Sun and heat

Samui is in the tropics, and the sun is strong even when it’s cloudy. Pack high-factor sunscreen, hats and rash vests for swimming. Get into the shade every hour or so and keep water bottles topped up. Younger children dehydrate faster than adults.

Sea safety and jellyfish

• Swim where there are lifeguards or swimming nets. Thailand’s marine authorities have installed jellyfish nets at some Samui beaches, including Chaweng and Lamai.
• Box jellyfish have been reported around Samui and Koh Phangan. Advice issued in 2025 was to swim within netted zones and stay out of the sea at dusk and at night.
• If someone is stung, pour household vinegar over the area for at least 30 seconds. Don’t rinse with fresh water, use ice or rub the sting. Then get medical help.
• During the monsoon months, waves can build on east-facing beaches. Obey any red flags.
• On our catamaran, life jackets, a first-aid kit and accident insurance are included. Children should wear a life jacket for every water activity.

Mosquitoes

The US CDC notes that dengue occurs throughout Thailand, with peak transmission in the rainy season. Use an insect repellent suitable for your child’s age, put children in light long sleeves at dawn and dusk, and sleep in air-conditioned or screened rooms.

Animals

At the elephant sanctuary, children should stay with an adult and follow staff instructions about where to stand. Around the island, teach children to leave street dogs and monkeys alone.

Getting around

Car seats aren’t standard in Thai taxis or tour vans. If you need one, bring it from home. We don’t recommend renting a motorbike with children.
