10 Best Things to Do in Koh Samui: A Local's Guide
Ang Thong Marine Park — 42 islands, accessible by private boat from Samui
Most Koh Samui guides are written by people who spent a week here and hit the same five tourist spots. This one is different. After years of living on this island, I can tell you exactly what is worth your time, what is overrated, and what most visitors completely miss. Here are the ten things that make Samui worth coming back to.
1. Find Your Beach (They Are Not All the Same)
Samui has over a dozen beaches, and picking the right one matters more than you think.
Chaweng Noi is the one I recommend most. It is the quieter southern extension of the main Chaweng strip — same beautiful sand, half the crowd. The water is calm, the beach curves gently, and the hillside above it is home to some of the island's best villas. Villa 369 sits right above this beach, which means you can walk down in five minutes or simply watch the ocean from the infinity pool.
Lamai is the second most popular beach and has a more laid-back, slightly rougher personality than Chaweng. Good for people who want a local vibe with easy access to restaurants and bars.
Maenam on the north shore is wide, quiet, and faces Koh Phangan. Great for families with small children — the water stays shallow for a long way out.
Silver Beach (Haad Thong Ta-Khian) is a hidden gem between Chaweng Noi and Lamai. Small, rocky at the edges, brilliant for snorkeling. Arrive early because parking is limited.
Insider tip: Visit the east coast beaches in the morning for calm, glassy water. Afternoons can bring a light chop. West coast beaches (Taling Ngam, Lipa Noi) are better for sunset sessions.

2. Day Trip to Ang Thong Marine Park
This is the single most spectacular day trip in the Gulf of Thailand. Ang Thong is an archipelago of 42 islands northwest of Samui — towering limestone karsts, hidden lagoons, jungle-covered peaks rising from turquoise water. It looks like the backdrop of a film, and in fact it was the inspiration for Alex Garland's novel The Beach.
How to get there: Speedboat tours depart from Nathon Pier or Bophut, taking about 45 minutes. Full-day tours include snorkeling, kayaking through sea caves, and a hike to the Mae Koh viewpoint overlooking the Emerald Lake.
Insider tip: Book a private speedboat rather than a group tour. It costs more (around 15,000-25,000 THB for the boat) but lets you visit islands at your own pace and avoid the 40-person crowd at each stop. The concierge at Villa 369 arranges these regularly and can get competitive rates with trusted captains.
3. Visit Wat Phra Yai (Big Buddha Temple)
The 12-metre golden seated Buddha at the island's northeast tip is Samui's most recognisable landmark. It has been here since 1972 and sits on a small island (Koh Fan) connected to the mainland by a causeway.
How to get there: Drive to the northeast corner of the island near the airport. Parking is free. Walk up the ceremonial staircase flanked by naga serpent rails.
Insider tip: Go at sunset. Most tour groups visit mid-morning, so by late afternoon the temple is nearly empty. The light on the gold statue against the evening sky is remarkable. Dress respectfully — knees and shoulders covered.
4. Explore the Fisherman's Village Night Market
Every Friday evening, the main street of Bophut's Fisherman's Village transforms into one of the best night markets in southern Thailand. Stalls sell everything from handmade jewellery and Thai silk to grilled seafood, mango sticky rice, and coconut ice cream.
How to get there: Head to Bophut Beach Road. The market runs from roughly 5pm to 11pm. Park on a side street and walk in — the main road closes to traffic.
Insider tip: Eat at the seafood stalls at the far end of the market, away from the entrance. The vendors there cater more to locals and the portions are larger. Also check the side sois (alleys) for smaller restaurants that stay open during market nights with special menus.
5. Hike to a Viewpoint
Samui's interior is mountainous and jungle-covered, and several viewpoints offer panoramic perspectives you will not get from the beach.
Overlap Viewpoint (Lad Koh) on the southern coast is the most popular — a series of rock platforms jutting out over the sea with views toward Lamai and the Five Islands. It is accessible by car or scooter (paved road all the way) and has a small bar at the top.
Jungle Club above Chaweng is a restaurant and viewpoint in one. The drive up is steep and best done in a 4x4, but the reward is a pool, cold drinks, and a 180-degree view over Chaweng Bay.
Insider tip: For a less-visited viewpoint, drive the ring road to the southwest corner and take the road up to the Pagoda Khao Hua Jook. It is a small hilltop temple with 360-degree views and virtually no tourists.
6. Watch (or Try) Muay Thai
Koh Samui has a strong Muay Thai scene, both as spectator sport and training opportunity. Chaweng Stadium hosts professional fights several nights a week, with a mix of Thai and international fighters. The atmosphere is electric — locals betting on fights, the sound of traditional music building with each round.
How to get there: Chaweng Boxing Stadium is on the main ring road south of Central Festival. Fights start around 9pm. Tickets at the door run 1,500-2,000 THB for ringside.
Insider tip: If you want to train, look for camps that welcome beginners for single sessions. A morning session typically costs 500-800 THB and lasts 90 minutes. It is one of the most memorable physical experiences you can have on the island — exhausting, humbling, and exhilarating.
7. Take a Thai Cooking Class
Learning to cook pad thai or green curry in the country where these dishes originated is a different experience entirely from following a recipe at home. Several schools on Samui offer half-day and full-day classes that start with a market visit to buy fresh ingredients.
Where to go: Sitca Cooking School near Lamai and Samui Institute of Thai Culinary Arts (SITCA) are both well-regarded. Classes run 1,500-3,000 THB per person and include everything.
Insider tip: For a more private experience, arrange an in-villa cooking class. Many private chefs on the island offer this service — they come to your villa, set up in the kitchen, and teach your group to cook three or four dishes that you then eat together. Villa 369's concierge can arrange this for guests, and it works particularly well for families or small groups who prefer not to join a public class.
8. Book a Luxury Spa Day
Thailand is famous for massage and spa culture, and Samui's spa scene ranges from excellent beachside Thai massage for 300 THB to full-day luxury wellness programmes at five-star resorts.
Where to go: Tamarind Springs is the standout. Built into natural boulders in the jungle above Lamai, it feels like bathing in a temple. Their signature herbal steam and rock pool experience is unlike anything at a conventional spa. The Four Seasons and Banyan Tree resort spas also offer world-class treatments.
Insider tip: For the best value, book a Thai massage at a small, local-run shop in Lamai or Maenam rather than a tourist-facing operation on the main road. The quality is often better and the price is 200-400 THB for a full hour. Look for places where Thai locals get their massages — that is the real quality indicator.
9. Go Island Hopping
Koh Samui sits in an archipelago, and the neighbouring islands are each worth a visit for different reasons.
Koh Phangan (30 minutes by speedboat) is famous for the Full Moon Party, but outside of party nights it is a beautiful island with quieter beaches, better diving, and a growing wellness scene. Haad Salad and Bottle Beach are two of the best beaches in the Gulf.
Koh Tao (two hours by high-speed catamaran) is one of the world's best and most affordable places to learn scuba diving. Even a single day trip for snorkeling is worthwhile — the coral around Japanese Garden and Shark Island is vivid and easily accessible.
Koh Madsum (15 minutes by longtail from Thong Krut) is a tiny, undeveloped island with one small resort, a white sand beach, and resident pigs that wander freely. It sounds gimmicky but it is genuinely charming and makes a great half-day escape.
Insider tip: Avoid the big group island-hopping tours that try to hit Phangan, Tao, and Nang Yuan in a single day. You spend most of your time on a boat and get about 40 minutes at each stop. Pick one island, go there properly, and enjoy it.
10. Chase the Best Sunsets
Samui's west coast faces the open Gulf, and the sunsets from this side of the island are consistently spectacular — especially from December through March when the skies tend to be clearest.
Top spots:
- Lipa Noi Beach: Wide, shallow, west-facing. Bring a towel and a cold drink from the nearby 7-Eleven. Simple and perfect.
- Nikki Beach: If you want a sunset with a scene — music, cocktails, pool — this is the spot. It is polished and pricey but the setting is undeniable.
- The Five Islands viewpoint: Just south of Lamai, five small rock islands sit offshore and catch the last light beautifully. Best viewed from the rocks at the southern end of Lamai Beach.
- Your villa terrace: Honestly, some of the best sunsets I have seen on this island have been from the upper deck of a hillside villa with a glass of wine, watching the sky go from orange to purple over the Gulf. If you are staying at a villa with a west or southwest exposure, you may not need to go anywhere.
Insider tip: The most vivid sunsets happen during the shoulder and monsoon months (May-October) when there are more clouds in the sky to catch the colour. January sunsets are beautiful but often clear-sky affairs that lack the drama of a partly cloudy monsoon evening.
Making It All Happen
The best way to experience Koh Samui is with a base that feels like home and a concierge who knows the island. Renting a private villa gives you space, privacy, and a kitchen for the nights you do not feel like eating out. Villa 369 sits above Chaweng Noi with panoramic ocean views and a team that can arrange everything on this list — from Ang Thong boat charters to in-villa cooking classes to Muay Thai sessions.
