On Koh Samui, choose Chaweng for nightlife and the most choice, Lamai for a slightly calmer version of the same, Bophut and Maenam on the north coast for families and a relaxed evening, Choeng Mon for a small bay near the airport, and the south and west coasts if you want quiet and sunsets.
Samui is Thailand's second-largest island, but TAT notes that you can drive all the way round it in a couple of hours, so no beach is far from any other. That makes the choice less permanent than on a long island like Koh Lanta. Still, where you sleep shapes your evenings, how much you spend on taxis and how often you can just walk into the sea.
The Tourism Authority of Thailand singles out Chaweng, Lamai and Taling Ngam among the island's beaches, and describes Bophut's old Chinese shophouses as its most charming village. Below, the coasts in the order most visitors meet them: the busy east, the north, and the quiet south and west.
Koh Samui's coasts in brief
- East (Chaweng, Lamai)

- Calmer water, Fisherman's Village, views of Koh Phangan
- South and west (Taling Ngam, Lipa Noi and others)
- Quiet, local, sunset-facing on the west
- Wettest months
- October to December, with November the wettest (Thai Meteorological Department averages)
- Driest month
- February
Chaweng: the busiest beach, for nightlife and choice
Chaweng is Samui's main beach and its main resort town. TAT recommends Hat Chaweng for sunbathing and swimming all day, and the sand is long, white and gently sloping. Behind it runs Chaweng Beach Road, with hotels at every price, restaurants, bars, clubs, shopping malls, clinics and pharmacies.
The beach is long enough to have different moods. The central part is the liveliest, with beach clubs and music in the evening. The northern and southern ends are quieter, with resorts set back from the sand. Wherever you stay, expect traffic and noise on the road behind the beach.
Jet skis and beach vendors are part of the scene. If you rent a jet ski, read our warning on jet ski rental scams first, and photograph the machine before you set off.
Who it suits: first-time visitors, groups of friends, people who want nightlife and to walk everywhere. Skip it if you want peace or a local feel.
Lamai: Chaweng's calmer neighbor
Lamai lies south of Chaweng on the east coast and is the island's second resort area. TAT puts it alongside Chaweng as a beach for swimming and sunbathing, and the famous Hin Ta and Hin Yai rocks, a pair of oddly shaped boulders, stand at its southern end. The town behind the beach has bars and restaurants, but on a smaller, more relaxed scale than Chaweng.
Lamai tends to be a little cheaper than Chaweng and suits travelers who want a proper beach and a choice of places to eat without the crowds. Some longer-stay visitors base themselves here for the same reason.
Who it suits: couples, budget travelers, longer stays and families who still want a lively town nearby.
Bophut and Fisherman's Village: evenings on foot
Bophut, on the north coast, has the most character of Samui's beach areas. Its Fisherman's Village is a narrow beachfront street of old wooden shophouses, now restaurants, cafés and boutiques. The Nation describes it as a walking street about a kilometer long along Bo Phut's Beach Road, lined with more than a hundred stalls when the market is on; the Bangkok Post calls the weekly walking-street market family-friendly.
The beach itself is pleasant rather than spectacular, with calmer water than the east coast in much of the year and a view across to Koh Phangan. Bophut is also close to Samui Airport. Smoking is banned on Bo Phut beach, one of 24 Thai beaches on the 2017 list; use the designated smoking areas behind it.
Who it suits: couples, families, older travelers, anyone who likes to stroll to dinner. Skip it if you want long, deep swimming beaches or late-night clubs.
Fisherman's Village is free and best on market night. The walking-street market is the easiest evening out on Samui for families: no entry fee and plenty of food from street stalls. Check the day with your hotel, as schedules change.
Maenam: the quiet family beach
Maenam, west of Bophut on the north coast, is long, calm and low-key. The Bangkok Post describes Maenam and Bophut as among the most family-friendly beaches on Samui, with gentler waves than elsewhere, and singles out Maenam's shallow water and soft sand for young children. Resorts range from simple bungalows to upscale villas, and the village behind the beach has local restaurants and shops.
Evenings are quiet, and for nightlife you take a taxi to Bophut or Chaweng. That is exactly why families and long-stay visitors like it.
Who it suits: families with small children, long stays, travelers who want calm. Skip it if you want to walk to bars.
Choeng Mon and the north-east bays
Choeng Mon is a small, curved bay at Samui's north-east corner, a short drive from both the airport and Chaweng. It feels sheltered and relaxed, with a few large resorts and a cluster of restaurants. Nearby, Big Buddha Beach (Bang Rak) takes its name from the large Buddha statue on a small island linked to the shore by a causeway, one of the island's best-known landmarks; it is handy for the airport, though the beach itself is less attractive than Choeng Mon.
Who it suits: couples and families who want a quiet resort stay with Chaweng's restaurants within a short taxi ride, and travelers with early flights.
The quiet south and west coasts
The south and west of Samui are where island life still feels local: fishing villages, coconut plantations, temples and far fewer resorts. TAT lists Taling Ngam on the west coast among the island's highlights. Several beaches on this side are shallow, with rocks or reef close to shore, so check the water before you book if swimming matters to you.
The big advantage of the west coast is the sunset. Beaches such as Lipa Noi and Taling Ngam face west across the water toward the islands of Ang Thong National Marine Park, the usual day trip from Samui; our guide to Ang Thong Marine Park covers it. The south coast has small bays and fishing piers rather than resort strips.
You need your own transport here. Grab works on Samui (Bolt does not cover the island), but waiting times are longer away from Chaweng, and taxis cost more over the longer distances. Our comparison of Bolt and Grab explains the apps, and our guide to scooter safety applies if you rent one. TAT's own warning is blunt: motorbikes cause many accidents and deaths on Samui, so wear a helmet and never ride after drinking.
Who it suits: repeat visitors, couples who want privacy, long stays and anyone who values sunsets over nightlife.
| Beach | Coast | Nightlife | Families | Best for |
|---|---|---|---|---|
| Chaweng | East | Lots | Fair | Choice, nightlife |
| Lamai | East | Some | Good | A livelier beach at lower prices |
| Bophut | North | Relaxed | Good | Fisherman's Village, dining |
| Maenam | North | Little | Very good | Calm water, long stays |
| Choeng Mon | North-east | Little | Good | Quiet bay near the airport |
| South and west | South, west | Very little | Fair | Sunsets, local life |
Samui's different rainy season
Samui is on the Gulf of Thailand, and its weather does not follow the Andaman pattern of Phuket and Krabi. According to the Thai Meteorological Department's 1991–2020 averages, October to December bring half of Samui's yearly rain, with November the wettest month by far, while June to August are relatively dry and February is the driest month of all. The wind and waves of the northeast monsoon are usually felt most on the east-facing beaches, Chaweng and Lamai.
Box jellyfish are the other seasonal risk. A Department of Marine and Coastal Resources research center reported in 2019 that it frequently observed them off Samui, Koh Phangan and Koh Tao from July to October, and it put warning signs and bottles of vinegar on the beaches of all three islands. Our guides to box jellyfish and rip currents and beach flags explain the first aid and the flags. TAT adds a simple rule: be careful swimming at night, especially alone.
Vinegar, not fresh water, for a jellyfish sting on Samui. Thailand's Department of Disease Control advises leaving the water, calling 1669, not rubbing the sting and pouring household vinegar over it for at least 30 seconds. Look for the vinegar posts on the beach before you swim.
Getting to your beach
Samui Airport is in the north-east, near Bophut, so Bophut, Choeng Mon, Big Buddha Beach and northern Chaweng are the quickest transfers. Ferries arrive on the west coast and in the north; our guide to getting to Koh Samui covers flights, ferries and joint tickets. Agree taxi fares before you set off, as TAT advises.
Many visitors combine Samui with its neighbors. The guides to Koh Phangan and the Koh Tao guide cover the next islands, and our Gulf island-hopping route links all three. For the rest of the island, see our Koh Samui guide.
Frequently asked questions
Which is the best beach on Koh Samui?
There is no single best one. Chaweng has the finest long swimming beach and the most going on; Lamai is similar but calmer; Maenam and Bophut are best for families and quiet evenings; the west coast has the sunsets. Choose by what you want to do after dark.
Chaweng or Lamai: which should I choose?
Choose Chaweng if you want the most restaurants, bars and nightlife within walking distance. Choose Lamai if you want a good beach with a smaller, more relaxed town and slightly lower prices. They are close enough to visit each other by taxi or Grab.
Where should families stay on Koh Samui?
Maenam and Bophut on the north coast are the usual choices, with calmer water and quiet evenings, and Fisherman's Village nearby for dinner. Choeng Mon is another good option. Chaweng works for families with older children who want more activities.
When is the rainy season on Koh Samui?
Mainly October to December, with November the wettest month, according to Thai Meteorological Department averages. That is different from Phuket and the Andaman coast. June to August are relatively dry on Samui, and February is usually the driest month.
Is Fisherman's Village in Bophut worth visiting?
Yes. Its old wooden shophouses, beachfront restaurants and weekly walking-street market make it the most atmospheric evening out on Samui, and it is easy to reach from the airport, Maenam and Chaweng. Go on market night for the full experience.
