Koh Samui is one of Thailand's easiest islands for families. The beaches are gentle, the resorts are used to children, the distances are small and the activities range from calm to thrilling. The key is to match the day to your children's ages, keep the schedule light and avoid trying to do everything. This guide covers the best beaches and hotels for families, the activities that work well with kids and the things to think about before you book.
Choosing a beach
Choeng Mon, on the north-east corner, has a calm, crescent bay with shallow water, which makes it the pick for families with young children. Bophut has a gentle beach, a village for dinner and a short drive to the airport. Chaweng is the liveliest, with the most shops and restaurants, and its long beach is good for older children and teenagers. In every area, check the flags and local advice before swimming, particularly in the wetter months from roughly October to December, when the sea can be rougher.
Where to stay
A resort with a kids club and big pools takes much of the work out of a family trip. Meliá Koh Samui, on Choeng Mon Beach, has a lagoon-style pool with a swim-up bar, a kids club with a mini water park and connecting rooms. SALA Samui Chaweng offers a kids club, family suites and private pool villas on the island's busiest beach. Anantara Bophut is a quieter beachfront option with an easy walk to Fisherman's Village. Four Seasons Koh Samui has a kids club and family villas in a calm, upmarket setting on the north-west coast. For a tighter budget, Chaweng Garden Beach Resort has a pool and a central beach location.
Animals and gentle activities
The ethical elephant sanctuary half day is a highlight for many families, with feeding, walking and mud bathing in a setting that puts the animals first. Choose a sanctuary that does not offer rides, and check the age guidance when you book. Pig Island is another child-pleaser, an easy speedboat hop to a beach where pigs wander, with snorkelling and a chance of dolphin sightings. The footgolf and botanical gardens round is a light, funny half day that works for school-age children and teenagers. A cooking class is a good rainy-day option, with children rolling, stirring and tasting.
Adventure for older children
Teenagers and confident older children often love the jungle zipline, the jeep safari with waterfalls and a swim, and the Ang Thong day with kayaking and snorkelling. Check minimum ages, height and weight limits and parental supervision rules, which vary by operator and activity. ATV quad rides are usually for older teenagers and adults, and small children often cannot drive. Muay Thai fight night and the cabaret show are better for teenagers than for young children, because of the noise, the late finish and the content.
Boat days with children
Speedboats are fast and bumpy, so for younger children, the bigger, slower boats and catamarans are calmer. Life jackets for children should be properly fitted, and you should bring seasickness tablets if your family is prone to it. A half-day trip to Pig Island is much easier than a full day to Koh Tao or Ang Thong, so start small. Check the weather policy and book free cancellation, because rough water cancels boats, especially in the late-year wet season.
Practical tips
Pack high-factor reef-safe sunscreen, rash vests, hats, a water bottle for every child, insect repellent and a basic first-aid kit. Samui is hot and humid, so build a rest into the middle of each day, and aim for morning activities. Taxis are not cheap and few have child seats, so ask your hotel about transfers with seats and consider a private tour with a driver-guide when you want a flexible day. Eat early, since the best family restaurants fill up by seven. Keep children away from stray dogs, monkeys and jellyfish, and check with your hotel about the local conditions. Plan one headline activity a day and leave the afternoon free for the pool, because tired children make for a poor second outing. Check each operator's age and health rules before you pay, and bring copies of any medical information for the children. With a calm beach, a family resort and one activity a day, Samui is as easy as family travel gets, and it rewards parents who keep the plan simple.
