20 Best Things to Do in Koh Samui – The Ultimate Family Guide
Koh Samui is the kind of island that gets under your skin, in the best possible way. Think swaying palms, turquoise waters, fresh coconut ice cream, and sunsets that stop you in your tracks. But beyond the beach-lazing, there’s a treasure trove of experiences that make it one of the most family-friendly destinations in Thailand.
If you’re travelling with children, you’ll be spoiled for choice when it comes to things to do in Koh Samui. The island blends adventure, culture, and kid-friendly fun so perfectly that your days can be as action-packed or as chilled as you like.
From calm, shallow bays for paddling to colourful temples, gentle hikes to waterfalls, and even ethical elephant encounters, here’s your complete guide to the 20 best things to do in Koh Samui with kids (and grown-ups who still love a bit of fun).
1. Relax on Silver Beach – Calm Waters for Little Swimmers
Silver Beach, also known as Haad Thong Ta-khian, is one of those places that make you wonder why everyone isn’t here. It’s a small, sheltered bay between Lamai and Chaweng, framed by huge granite boulders that naturally protect it from waves, making it one of the safest swimming spots on the island.
Families love it for the gentle, crystal-clear water and fine white sand that’s perfect for sandcastle building. Older kids can snorkel around the rocks where colourful fish dart between corals.
Insider Tip: Arrive before 10am to snag a shady spot under the palm trees. The beachfront restaurants are family-friendly and serve both Thai favourites and Western comfort food.
Getting there: 10 minutes from Lamai, 20 from Chaweng.
Perfect for: All ages, especially toddlers and preschoolers.
2. Visit the Iconic Big Buddha Temple (Wat Phra Yai)
One of the most famous things to do in Koh Samui is visiting the 12-metre-tall golden Buddha. Sitting on its own small island, connected by a causeway, this statue is an incredible sight – and the panoramic views from the top are just as impressive.
Kids enjoy the gentle climb up the staircase, and it’s a great way to introduce them to Thailand’s Buddhist culture in a calm, respectful setting. You’ll also find small market stalls selling snacks, drinks, and souvenirs at the base.
Family Tip: Shoulders and knees should be covered. Carry a light scarf or sarong in your day bag to use as a cover-up.
Getting there: 10 minutes from Fisherman’s Village, 15 from Chaweng.
Perfect for: Ages 3+ who can manage steps.
3. Splash Out at Coco Splash Adventure & Waterpark
When you’re looking for fun, active things to do in Koh Samui with younger kids, Coco Splash is perfect. This boutique waterpark in Lamai has a safe, shaded toddler pool, small but thrilling slides for older kids, and even a mini-golf course.
The best part? It’s nowhere near as crowded as larger parks, so you can relax while the kids zoom down slides or paddle happily. Parents can grab a coffee or join in the fun – no judgement.
Family Tip: Bring water shoes, as the floor can get warm in the sun.
Getting there: Central Lamai, 15 minutes from Chaweng.
Perfect for: Ages 2–12.

Beyond the food, you’ll find stalls selling clothes, handmade jewellery, and quirky souvenirs. Live music drifts through the air, and the energy is contagious.
Family Tip: It’s busy, so a baby carrier is easier than a pram here. Go early for fewer crowds and more choice.
