Koh Samui, Thailand’s second-largest island, is a tropical haven where palm-fringed beaches, lush jungles, and luxury resorts come together to offer something for every traveller. Whether you’re chasing sunsets, looking for cultural gems, or just craving authentic Thai street food, Koh Samui delivers — and then some.
Planning your first visit? Here’s a curated guide to the top 10 things to do in Koh Samui, guaranteed to make your getaway unforgettable.
1. 🛕 Visit the Big Buddha Temple (Wat Phra Yai)
A must-see landmark in Koh Samui, the Big Buddha is a 12-meter golden statue sitting proudly on a small rocky island connected by a causeway. It’s one of the island’s most iconic sights, especially during sunrise and sunset. The temple complex also includes smaller shrines and souvenir shops.
Top Tip: Dress modestly (cover shoulders and knees) and visit early in the morning to avoid crowds and enjoy cooler temperatures.
2. 🏝️ Relax on Chaweng Beach
If you’re after soft white sand and lively beach vibes, Chaweng Beach is the place to be. It’s the most popular beach on the island, offering everything from jet-skiing and parasailing to cocktail bars and beach clubs.
First-timer advice: It’s ideal for both sunbathing and nightlife. Families may prefer the quieter southern end.
3. 🍛 Explore Fisherman’s Village in Bophut
Fisherman’s Village in Bophut is a charming, historic street lined with trendy boutiques, cafes, and restaurants set in old Chinese-Thai shop houses. Every Friday, the area transforms into a bustling night market filled with street food, souvenirs, live music, and local crafts.
Don’t Miss: Try the grilled seafood skewers, banana pancakes, and fresh coconut ice cream!
4. 🌊 Take a Day Trip to Ang Thong National Marine Park
Nature lovers will fall in love with Ang Thong National Marine Park, a protected archipelago of 42 islands. Think emerald lagoons, limestone cliffs, and hidden coves perfect for kayaking, snorkelling, and hiking.

5. 🧘♀️ Join a Beachfront Yoga or Spa Session
Koh Samui is known for wellness retreats, and whether you’re a complete beginner or a seasoned yogi, you’ll find a class for you. Many resorts and independent studios offer sunrise yoga, sound healing, or traditional Thai massages right by the beach.
Recommended Spot: Tamarind Springs Forest Spa – an open-air jungle spa experience unlike any other.
6. 🐘 Visit an Ethical Elephant Sanctuary
Skip the elephant rides and instead visit a sanctuary that focuses on ethical tourism. At places like Samui Elephant Haven, you can observe rescued elephants living freely and behaving naturally in a safe environment.
Why It Matters: These sanctuaries promote education, conservation, and the humane treatment of Thailand’s beloved elephants.
7. 💦 Chase Waterfalls – Hin Lat & Na Muang
