Top 10 Things to Do in Koh Samui – Thailand DMC Expert Guide

Koh Samui is an island paradise that offers a mix of beautiful beaches, lush jungles, and vibrant culture. As a local Thailand DMC (Destination Management Company) expert, I’ve curated this guide to the top 10 things to do in Koh Samui, blending popular attractions with lesser-known local gems. Whether you’re planning your Koh Samui itinerary or looking for a Samui travel guide, these recommendations will help you experience the best of the island – from iconic landmarks to unique adventures.

1. Big Buddha Temple (Wat Phra Yai) – Koh Samui’s Iconic Landmark

The Big Buddha Temple is Koh Samui’s most famous cultural landmark, featuring a majestic 12-meter golden Buddha statue that can be seen from miles away. Perched on a small islet off the northeastern coast, this impressive statue has been a symbol of the island’s spiritual heritage since its construction in 1972. Visitors can climb the steep staircase flanked by dragon-like Naga statues to reach the platform, which offers panoramic views of the ocean and nearby islands.

Once at the top, you’ll feel a serene atmosphere as locals light incense and pray. Around the temple grounds, there are small shrines, bells to ring for good luck, and vendors selling amulets and coconut ice cream. Local Expert Tip: Visit in the early morning or around sunset to avoid crowds and heat, and remember to dress modestly (cover shoulders and knees) out of respect. Just a few minutes away is Wat Plai Laem, another stunning temple complex with a colorful 18-armed Goddess statue – a worthwhile add-on to your cultural tour.

2. Ang Thong National Marine Park – Pristine Island Adventure

A day trip to Ang Thong Marine National Park is a must-do adventure for nature lovers. This protected archipelago of 42 emerald islands in the Gulf of Thailand is famed for its towering limestone cliffs, hidden lagoons, and vibrant marine life. Embark on a speedboat or catamaran tour from Koh Samui to spend the day island-hopping through Ang Thong’s most scenic spots. You can snorkel above coral reefs teeming with tropical fish, kayak along secluded coves, or hike through jungle trails to breathtaking viewpoints.

Highlights of Ang Thong include the Emerald Lake (Talay Nai) on Koh Mae Koh, a stunning turquoise saltwater lagoon nestled in a crater, and the panoramic viewpoint on Koh Wua Talap, which rewards hikers with a 360° view of the islands scattered across the sea. Many tours also provide a beachside Thai lunch on a quiet island, allowing you to relax on powdery white sands under palm trees. Local Expert Tip: Book a tour that departs early to beat the crowds, and bring sunscreen, a hat, and plenty of water. If you’re up for it, the short but steep hike to the viewpoint is worth the effort for incredible photos of this tropical paradise.

3. Na Muang Waterfalls – Tropical Oasis in the Jungle

Koh Samui’s interior is home to lush rainforests and waterfalls, and the most famous are the Na Muang Waterfalls – two cascading falls nicknamed “Purple Waterfalls” for the purple-hued rocks beneath the water. Na Muang 1 is easily accessible by a short walk and features a large natural pool at its base, perfect for a refreshing dip on a hot day. Locals and visitors alike enjoy cooling off here amid the jungle scenery. Further uphill is Na Muang 2, a taller waterfall reached by a bit of hiking; the trail can be steep but offers rewarding views of water plummeting through the forest.

Surrounded by tropical foliage and the sounds of birds and cicadas, the Na Muang waterfalls provide a peaceful escape into nature. Along the path, you might find small stalls selling fresh fruit shakes and young coconuts to quench your thirst. Local Expert Tip: The waterfalls are most impressive during or just after the rainy season (roughly September through November) when water flow is high – in the dry months they may slow to a trickle. Wear comfortable shoes with good grip, as the rocks and paths can be slippery. After your waterfall visit, consider stopping by a nearby roadside stall for some cold coconut water or a grilled chicken snack as a tasty reward.

4. Secret Buddha Garden – Hidden Hilltop Sanctuary

Tucked away in Koh Samui’s mountainous interior is the Secret Buddha Garden (also known as Magic Garden), a hidden gem often missed by casual tourists. Created in 1976 by an old local durian farmer, this secluded garden is filled with moss-covered statues of Buddhas, deities, animals, and celestial beings, all set amidst lush jungle foliage and gentle streams. Wandering through the garden feels like stepping into a fairytale – you’ll encounter serene stone figures meditating, musicians playing instruments, and mythical creatures guarding the corners of this tranquil retreat.

The Secret Buddha Garden’s location on a high hill means you’ll also get cooler air and glimpses of beautiful island views on the journey up. It’s a peaceful spot to reflect and admire the blend of nature and art, far from the island’s beaches and bars. Local Expert Tip: Reaching this spot requires a drive up steep, winding roads – consider hiring a 4x4 vehicle or joining a local island safari tour that includes the garden as a stop. Early morning or late afternoon visits are best for softer light and cooler temperatures. Combine this trip with a stop at a nearby mountain viewpoint or the island’s highest temple (Khun Si or Teepangkorn) for an unforgettable day exploring Samui’s highlands.

5. Fisherman’s Village, Bophut – Local Charm and Night Market

For a taste of Samui’s old-world charm and a great evening out, head to Fisherman’s Village in Bophut. This historical enclave by the sea used to be a fishing community and still retains a rustic vibe with its traditional wooden Chinese shop-houses, quaint cafés, and boutique shops. Stroll the narrow walking street and you’ll find art galleries, stylish restaurants, and laid-back bars with views of the ocean. It’s an ideal place to slow down and soak in a more authentic local atmosphere away from the busier resort areas.

The highlight of Fisherman’s Village is the Friday Night Walking Street Market, when the entire village transforms into a lively open-air market after dusk. Vendors line the street selling everything from handcrafted souvenirs and clothing to an amazing array of Thai street food. Follow your nose to grills sizzling with satay skewers, try spicy papaya salad made fresh to order, and don’t miss the banana pancakes drizzled with chocolate for dessert. Live music and street performers add to the festive ambiance. Local Expert Tip: Arrive before sunset to grab a seat at a beachfront restaurant – you can enjoy a fresh seafood dinner with a sunset view, then dive into the night market chaos. Bargaining is common for souvenirs, so friendly haggling can get you a better price. If you’re not in Bophut on a Friday, fear not – other villages like Maenam (Thursday) and Lamai (Sunday) host weekly night markets where you can experience local flavors and culture on different nights.

6. Chaweng Beach – Sun, Sand, and Vibrant Nightlife

No trip to Koh Samui would be complete without spending time on Chaweng Beach, the island’s longest and most popular stretch of sand. By day, Chaweng’s 7-kilometer beach offers soft white sand and clear turquoise waters ideal for swimming and sunbathing. You can rent jet skis, go parasailing, or simply relax under a palm tree with a coconut in hand. Many resorts, beach clubs, and massage pavilions line the shore, so whether you seek adventure or relaxation, Chaweng has something for everyone.

By night, Chaweng transforms into the heart of Samui’s nightlife. As the sun sets, beach bars and clubs come alive with music, fire shows, and dancing under the stars. The Green Mango strip and surrounding streets offer a variety of nightlife – from open-air bars with live DJs to upscale lounges and the famous ladyboy cabaret shows. It’s an energetic scene where you can party until dawn if you wish. Local Expert Tip: For a calmer beach experience, the north end of Chaweng tends to be quieter, or consider visiting nearby beaches like Lamai or the tucked-away Silver Beach for a more relaxed vibe. At night, always keep an eye on your belongings and drink responsibly. If clubbing isn’t your style, an evening stroll along Chaweng’s beach under the moonlight, with the sound of gentle waves, can be just as magical.

7. Hin Ta & Hin Yai Rocks – Natural Curiosities of Legend

Koh Samui isn’t just about beaches and temples – it also has its share of quirky natural wonders. The Hin Ta & Hin Yai rocks (Grandfather and Grandmother Rocks) are unusual granite formations on the shore of Lamai Beach that have become a famous stop for their uncanny resemblance to male and female anatomy. Carved by wind and water over countless years, these rocks are both a source of local legend and light-hearted humor among visitors. According to one Thai folktale, an elderly couple tragically shipwrecked nearby and transformed into these rocks, hence their names.

Visiting Hin Ta & Hin Yai is a quick but memorable experience. A viewing platform allows you to see and photograph the rock shapes set against the sparkling sea. You’ll also find a small cluster of stalls selling souvenirs and local snacks at the entrance path. Local Expert Tip: Try a taste of “Kalamae”, a traditional Samui sweet made from coconut caramel, often sold by vendors around the rocks – it’s a delicious souvenir to bring home. While the site is playful in nature, remember to be respectful in your behavior as local Thai people consider the area part of their folklore. You can combine this stop with a visit to Lamai’s temples or a refreshing swim at Lamai Beach, which is just a short walk away.

8. Samui Elephant Sanctuary – Ethical Elephant Experience

Elephants hold a special place in Thai culture, and an ethical encounter with these gentle giants is one of the most rewarding things to do on Koh Samui. The Samui Elephant Sanctuary (the island’s first ethical elephant sanctuary) offers a humane alternative to the old elephant trekking camps. Here, rescued elephants – many from logging or riding industries – roam freely in a natural habitat, without chains or rides. Visitors can spend a half-day observing these magnificent creatures as they forage, socialize, and enjoy mud baths, all under the watchful care of trained staff who ensure the elephants’ well-being.

During a visit, you’ll typically have the opportunity to help prepare the elephants’ food and feed them by hand, an unforgettable experience as you stand face-to-trunk with these animals. Guides share each elephant’s backstory and educate visitors about elephant conservation and welfare. Watching an elephant happily dust itself with sand or trumpet to a friend across the field is a heartwarming sight that stays with you long after your trip. Local Expert Tip: Book your sanctuary visit in advance – group sizes are limited to minimize stress on the animals and slots can fill up quickly, especially in high season. Wear clothes you don’t mind getting dirty (you might get splashed with mud or fruit juice during feeding time) and closed-toe shoes. Importantly, avoid any attractions on the island that offer elephant riding or performances, as they are harmful to the animals – support sanctuaries that prioritize the elephants’ welfare for a truly meaningful experience.

9. Wat Khunaram – The Mummified Monk of Koh Samui

For a deeper insight into local culture and spirituality, pay a visit to Wat Khunaram, a Buddhist temple most famous for its mummified monk. Inside a glass case sits the well-preserved body of Luang Pho Daeng, a revered monk who passed away in 1973 while meditating. Remarkably, decades later, his body shows little sign of decay – a testament to his dedication and the reverence in which he’s held. While at first it might seem unusual to outsiders, local Thai people view the mummified monk with deep respect. He serves as a powerful reminder of Buddha’s teachings on the impermanence of life and the importance of spiritual practice.

The temple itself is modest and peaceful. You may see local devotees lighting incense and offering flowers, praying for guidance or good fortune. Monks are often present, chanting or going about their daily routines, giving the temple an authentic working atmosphere.
Local Expert Tip: When visiting Wat Khunaram (and any temple in Thailand), dress respectfully by covering your shoulders and knees, and remove your shoes before entering any sacred area. It’s okay to quietly observe and even take photos of the mummified monk, but do so in a respectful manner. If you’re exploring the island by car or tour, Wat Khunaram is conveniently located on the route to Na Muang Waterfall and the south side of Samui, making it easy to combine with other sights. Take a moment here to absorb the spiritual ambiance – it’s a unique cultural experience that contrasts with the island’s more commercial attractions.

10. Take a Thai Cooking Class – A Taste of Samui’s Culture

One of the most enriching ways to connect with local culture is through its cuisine. Taking a Thai cooking class in Koh Samui allows you to learn the secrets behind your favorite Thai dishes and bring those skills home with you. Many reputable cooking schools and even some resorts on the island offer half-day classes where a local chef will guide you through preparing several dishes such as Tom Yum soup, Green Curry, Pad Thai, or Som Tam (papaya salad). Classes are hands-on – you’ll chop herbs, grind curry paste, and stir-fry over a wok, experiencing the delightful aromas of lemongrass, chili, and coconut milk as you cook.

Often, the experience begins with a market tour. In the morning, you might be taken to a local fresh market to pick out ingredients. This is a wonderful chance to see daily Samui life as vendors sell tropical fruits, spices, and seafood. Your instructor will show you how to choose the freshest produce and explain exotic items unique to Thai cooking. Back in the kitchen, you’ll get personalized instruction in a fun, small-group setting. The best part comes at the end, when you sit down to feast on the dishes you prepared – a delicious reward for your efforts! Local Expert Tip: Opt for a class that includes a market visit for the full experience, and come hungry because you will be eating a lot. Don’t worry if you’re not an experienced cook – Thai recipes can be quite forgiving, and teachers provide step-by-step help. You’ll also receive recipe cards to recreate the dishes at home, so you can impress friends and reminisce about your Samui trip through the flavors of Thailand.

Koh Samui truly offers something for every traveler, and these ten activities showcase the island’s diverse charms. From idyllic beaches and marine adventures to cultural landmarks and local experiences, you can tailor an itinerary that captures the essence of Samui.
