An east-coast island where kids build sandcastles on the calm, shallow water of Klong Prao, swim in the pool at Klong Plu Waterfall just a few minutes' walk from the car park, watch the fish from a glass-bottom boat off Koh Rang, meet elephants without riding them, then head back to a resort with a children's pool — Koh Chang is the family beach trip that's closer to Bangkok than the Andaman islands.
Koh Chang is Thailand's second-largest island, off the east coast in Trat province, and it's one of the easier islands to bring kids to — several beaches have calm, shallow water with gentle waves, there are family resorts with children's pools, and there's plenty kids can actually do on both land and sea. Best of all, it's closer to Bangkok than the Andaman islands: no flight needed, just a drive or van to the ferry at Trat.
The headline things to do cover every age — Klong Prao and White Sand Beach have shallow water you can wade into for ages, ideal for little ones building sandcastles; Klong Plu Waterfall is only a ~15-minute walk from the car park and has a pool kids can swim in at the base; snorkelling and glass-bottom boat trips to Koh Rang or Koh Wai suit older kids who want to see fish and coral; and an ethical no-riding elephant centre lets kids feed and bathe elephants humanely.
This guide covers the things kids of every age can actually do, with honest advice on what you have to plan for: the journey is fairly long and involves a ferry, the island roads are steep and winding (take care if you self-drive), the May–October rainy season brings choppy seas and some cancelled boat tours, and a few beaches have rocks or coral exposed at low tide — plus which beach to base on for a family. All of it checked.
We've gathered the family-friendly stays — resorts on Klong Prao with shallow water for little kids, places on White Sand Beach within walking distance of restaurants and convenience stores, and quieter bases on Kai Bae. Pick a west-coast beach that makes a family day easier, and skip the southern party zone that isn't suited to children.

White Sand Beach is Koh Chang's main, busiest beach — a convenient base for first-time families because you can walk to restaurants, convenience stores and shops for the basics. It's a long stretch of white sand, and the water at the northern end is fairly shallow with gentle waves, so kids can dig and paddle. There are plenty of beachfront resorts and restaurants to choose from, and the sunset stroll along the sand is lovely in the evening. It suits families who want both the beach and the convenience of finding food and supplies. One thing to know: parts of the beach have rocks exposed at low tide, so pack water shoes for the kids.

If you have little kids, Klong Prao is the answer — a long beach that's quieter than White Sand Beach, with soft sand, shallow water and gentle waves. At low tide you can walk out for ages without having to swim. Kids build sandcastles, collect shells and paddle in the shallows, and there's a row of family resorts with swimming pools to alternate with. Kids swim in the sea in the morning, then cool off in a resort pool — the most relaxed beach day on Koh Chang, and it never feels crowded. The Klong Prao estuary at one end is good for a kayak among the mangroves with older kids.

For a day that swaps the sea for a waterfall — Klong Plu is the biggest waterfall on Koh Chang, and it's good for kids because it's only a ~15-minute walk from the car park to the falls along a shaded, not-too-steep path. At the base there's a pool kids can swim in, with cool, clear fresh water and small fish to spot — kids love alternating fresh water with the sea. It works as a half-day of nature plus a swim. It's inside the Mu Ko Chang National Park, with rangers on hand and a clear, marked trail.

Kai Bae sits just south of Klong Prao, a quiet beach with little islands sitting just offshore that make a pretty backdrop for photos. At low tide some families can walk out to the nearest islet (check the tide and safety first). The water is clear and the mood relaxed, and nearby is the Kai Bae Viewpoint, where you look out over a string of islands at a beautiful sunset. It's a lovely place to bring kids in the early evening when the sun softens — for a family photo and a walk, then dinner by the beach. An easy evening for kids and adults alike.
On Koh Chang, the resort itself is a family activity — many beachfront resorts on Klong Prao and White Sand Beach have a swimming pool with a shallow children's section where kids can play all day without going anywhere. The bonus: on a rainy day, when the sea is choppy or the kids are tired, the resort pool is the hero, and it's safer than the open sea. Some resorts run kids' activities, kayaking in the estuary, and lend out rubber rings. Pick a resort with a kids' pool separate from the adult one, right by a calm shallow beach, and parents get to rest too while the kids stay happy.

For families with older kids, or anyone who wants the kids to see the underwater world — boat trips out to Koh Rang (inside the national park) and Koh Wai have clear water and shallow coral for good snorkelling. Many tours include a glass-bottom boat, so even little ones can watch fish and coral through the floor without getting in. Older kids who can swim snorkel alongside parents in a life jacket. Tours usually stop at several spots with lunch on board — for kids, choose a family tour that doesn't pack in too many stops.
Koh Chang takes its name from its elephant-shaped silhouette, and the island has elephant centres that have shifted to no-riding visits, which is better for the animals and a good lesson for kids. The focus is on feeding, bathing and learning about elephant behaviour rather than sitting on their backs — much better for an elephant's spine. Kids get close to the elephants safely under staff supervision and learn why we don't ride them. It's a memorable visit that quietly teaches children about caring for animals the right way. Choose a centre that clearly states no riding, where the elephants have room to walk and shade, and that doesn't use hooks.

Bang Bao Pier is at the southern end of the island, an old fishing village whose houses and shops are built along a wooden jetty out over the sea — a fun stroll with kids. Along both sides are souvenir shops, cafes and fresh seafood restaurants where you pick your fish or prawns. Kids get to see the fishing boats and tour boats lined up, and there's a little lighthouse at the end of the jetty for a photo. It's also the departure point for snorkelling tours and island-hopping boats, so if you're heading out the next day it's worth a scout. An easy half-day of a walk plus a seafood meal.
Not every day has to be an outing — on a rainy day (Koh Chang gets heavy rain in the wet season) or when the kids are worn out from travelling, the resort downtime day is the hero. Many family resorts have a covered pool or sala so kids can swim even in light rain. Kids swim in the children's pool, play with rubber rings, colour, read the books you packed or watch cartoons, while parents get a poolside break. Some resorts have table tennis, a playground or a games corner. A day like this keeps the trip from wearing everyone out and lets kids recharge for the next day. Pack books, small toys and crayons — they help a lot when it rains all day.

Good news for families — almost every restaurant on Koh Chang will make a dish mild or non-spicy, and there's always something kids eat easily, like fried rice, pad thai, rice with an omelette and stir-fried vegetables. The beachside star is mild grilled and steamed seafood — grilled prawns, steamed fish with lime (ask for little chilli), shellfish and squid — plus fresh coconut water and tropical fruit kids love. Western places around White Sand Beach do pizza, pasta and Western food if your kids want a change. Convenience stores carry milk, snacks and yogurt. Stick to bottled water.

Koh Chang isn't an easy day trip — from Bangkok it's a ~5-hour drive or van ride to the pier at Trat, then a 30–45 minute car ferry across. The ferry takes vehicles, so self-driving is convenient once you're on the island. With young kids, stay several nights rather than do a there-and-back trip, to allow for the travel time and let kids rest. Bring snacks and toys for the road and the ferry, plus kids' motion-sickness tablets. Booking the ferry and a transfer package ahead makes it smoother.
Koh Chang is a mountainous island, and the coastal road has some steep climbs and hairpin bends, especially heading south (Kai Bae to Bang Bao). If you self-drive, take extra care, use a low gear going downhill and don't rush. The island has no metro or train — the main ways around are shared songthaews (a set fare per trip), rental cars or rented motorbikes. With young kids, a rental car or songthaew beats a motorbike (motorbikes on the steep hill roads are dangerous, and you need a helmet plus a licence). Songthaews and rental cars usually don't have child seats, so bring your own if a young child needs one.
The best months for families are November to April: clear seas, gentle waves, good sun and all the boat tours running. May to October is the rainy season — frequent rain, a choppier sea, sometimes murky water, and many snorkelling tours cancel on rough days. Some resorts and businesses close in the low season. If you come in the rains, plan indoor options (resort pool, waterfall, in-resort activities) and check the forecast. The upside of the wet season is fewer people and lower prices, but for a family that wants the sea and boat trips, the dry season is the better bet.
Some Koh Chang beaches have rock or coral exposed at low tide, and some stretches are mudflat, which makes wading awkward and can hurt little feet — so always pack kids' water shoes and check the tide times. At high tide the water is clearer and better for swimming. The shallowest, easiest beaches for little kids are Klong Prao and the northern end of White Sand Beach, while some southern spots are deeper or have stronger waves. Keep kids where they can touch the bottom and in sight at all times — many Koh Chang beaches don't have lifeguards, so you supervise the kids yourself.
Food on the island can be made mild almost anywhere — fried rice, pad thai, omelette, steamed seafood — and there are Western restaurants around White Sand Beach if your kids want a change. Convenience stores and minimarts near the main beaches carry milk, snacks, water, diapers and the basics, but the brands and sizes may not match a Bangkok mall. If your child uses a specific formula, a particular diaper size, or any regular medication, stock up in Bangkok or Trat for the whole trip. Many resorts offer a kids' menu and an extra bed on request. Stick to bottled water.
Koh Chang has clinics and a small hospital on the island for routine cases, but serious ones may need to cross to a hospital in Trat — so take out travel insurance and bring your own children's first-aid basics (fever medicine, motion-sickness tablets, insect repellent, plasters). On mosquitoes: Koh Chang is a jungly island with mosquitoes in the evening and at night, so use repellent and long sleeves on kids. On connectivity: the signal is good around the main beaches, but it can be weak deep in the jungle or at the far tip, so have an eSIM or SIM ready. Most payments are cash; bigger places take transfers and cards.
