Koh Samui Beaches Compared: Where to Stay and What to Skip

Koh Samui’s beaches are not interchangeable, and the beach you book decides your whole trip. Chaweng is busy and convenient, Choeng Mon is calm enough for toddlers, Maenam is quiet and good value, and picking the wrong one means spending your holiday in a taxi on the ring road.

This guide answers three questions: which beach to base yourself on, which months to book, and which of the island’s famous sights and day trips are worth your time. If you are a family wanting calm water, a couple wanting quiet, or a group wanting to be near the action, there is a clear answer for each of you below.

1. Koh Samui at a Glance

Koh Samui (written Ko Samui on official maps) sits in the Gulf of Thailand, roughly 470 km south of Bangkok as the crow flies. At 228.7 square kilometres it is Thailand’s second largest island after Phuket, which matters more than it sounds: the beaches are far enough apart that where you sleep shapes what you can easily reach.

2. The Beaches: Which One to Base Yourself On

Think of Samui as two coasts. The east coast holds the two big, lively beaches. The north coast is calmer and slower, with smaller bays and a better evening village. Here is how each one actually differs.

Chaweng: busy, convenient, and loud after dark

Chaweng is the island’s biggest and busiest beach, a long sweep of pale sand on the east coast with the widest choice of hotels, restaurants and shops anywhere on Samui. If you want everything within walking distance and do not mind company, this is the easy answer.

• Best for: first-time visitors, groups of friends, short stays where convenience beats calm
• Not for: light sleepers, or families who want quiet evenings, since Chaweng is also the island’s nightlife centre
• Watch for: red no-swimming flags in the monsoon months, when onshore winds bring big surf to the east coast

Lamai: Chaweng’s calmer, cheaper sibling

Lamai is the second most popular beach, south of Chaweng, with the same swimmable sand at a lower volume and usually a lower price. It suits travellers who want restaurants on the doorstep without Chaweng’s crowds.

• Best for: couples and budget travellers who still want a lively main strip
• Not for: anyone wanting true seclusion

Bophut: the best evenings on the island

Bophut, on the north coast, has calm, shallow water and the island’s most enjoyable evening area, Fisherman’s Village, a strip of old wooden shophouses turned into restaurants and small shops. The beach itself is narrower and less striking than Chaweng’s, so you book Bophut for the evenings rather than the sand.

• Best for: couples, food lovers, families who want a relaxed base with good dinners nearby
• Not for: people whose priority is a wide, postcard beach

Maenam: quiet, long and good value

Maenam is a long stretch of golden sand on the north coast, quieter than anywhere on the east side and generally cheaper. It is the base for a slow week of reading and swimming.

• Best for: long stays, budget beachfront, travellers who will happily drive for dinner
• Not for: anyone who wants nightlife or a choice of restaurants on foot

Choeng Mon: the family pick

Choeng Mon is a small bay on the northeast tip, around ten minutes by road from Chaweng. Its water is calm and shallow, so small children can paddle without being knocked over by waves. It is home to several of the island’s more upmarket resorts.

• Best for: families with young children, couples wanting quiet within reach of Chaweng
• Not for: tight budgets, since the accommodation leans premium

Big Buddha beach and Hua Thanon

Big Buddha beach (Bang Rak) on the north coast is named after the temple on its headland and is handy for the airport, but it is a base for convenience rather than for the beach. Hua Thanon, south of Lamai, is a predominantly Muslim fishing village with traditional wooden houses and a fish market that supplies much of the island. It is a short, interesting stop rather than a place to stay for a beach holiday.

3. When to Go, and When Not To

Samui runs on a different weather calendar from Phuket and the Andaman coast, which catches many travellers out. The island’s heaviest rain falls from mid October to early December, when the northeast monsoon drives wind and swell onto the east coast. Phuket’s wet season, by contrast, peaks in the middle of the year.

• January to April: the best window. Dry, settled weather and calm seas. February is usually the driest month of all
• May to September: warm and mostly workable, with passing showers. A sensible choice if you cannot travel early in the year
• Mid October to early December: the one stretch to avoid for a beach trip. Red no-swimming flags go up on east coast beaches including Chaweng when the surf is dangerous, and Ang Thong National Marine Park normally closes from 1 November to 15 December

Room rates do tend to soften in the wetter months, but a cheaper room is poor value if the sea is closed to swimmers. If your dates are fixed in November, plan the trip around food, the Big Buddha and the island’s villages, and treat any swimming as a bonus.

4. Getting In and Getting Around

Getting to Koh Samui

• By air: Samui Airport is privately owned by Bangkok Airways, which runs the flights from Bangkok. Scheduled flight time from Suvarnabhumi is about 1 hour 15 minutes. Scoot also flies direct from Singapore
• By ferry: boats cross from Donsak pier near Surat Thani on the mainland. The Lomprayah catamaran to Nathon pier takes about 45 minutes; the Seatran car ferry takes around 1 hour 30 minutes
• Our view: flying is the expensive but simple option. The ferry is cheaper but only makes sense if you are already on the mainland or coming from another island

Getting around the island

A single ring road, 51 km long, circles Samui, so every beach is on one loop. Taxis and hired cars are the straightforward options for most visitors.

Scooters are everywhere, but the rules are specific. To ride legally as a tourist you need a motorcycle licence from your home country plus an International Driving Permit carrying the motorcycle endorsement. Since June 2025, rider and passenger must both wear helmets, and the fine for not doing so rose to 2,000 THB per person. If you do not already ride a motorbike at home, Samui’s hills and traffic are not the place to learn: hire a car or use taxis instead.

5. What Is Actually Worth Doing

Ang Thong National Marine Park

Ang Thong is the day trip that justifies the boat. It is an archipelago of 42 limestone islands covering 102 square kilometres, about 30 km off Samui, and the scenery is the real thing: jungle-topped cliffs, quiet channels and a saltwater lake.

• Entry: 300 THB for foreign adults, 150 THB for children aged 3 to 14, usually bundled into the tour price
• Hours: 8:00 to 17:00 daily
• Closed: normally 1 November to 15 December, depending on weather
• Access: only through licensed tour operators, with hotel pickup
• The two highlights: the Wua Ta Lap viewpoint, a steep 500 m trail of 25 to 30 minutes, and the emerald Thale Nai lake on Ko Mae Ko, about a 20-minute walk

A speedboat takes roughly 45 to 60 minutes each way; the larger, slower boats take about 90 to 120 minutes. The viewpoint climb is steep and rocky, so it is not for young children or anyone with mobility problems. Wear proper shoes, not flip-flops.

Ko Tao and Koh Nang Yuan

Ko Tao is known as one of the cheapest places in the world to learn to dive, and day tours from Samui pair it with Koh Nang Yuan, three small islands joined by sandbars with a famous viewpoint. The boat ride is about 1 hour 30 minutes each way.

• Nang Yuan charges a separate entry fee, listed at 250 THB per adult in 2026 guides, and is open from 10:00 to 15:00
• Single-use plastic water bottles are not allowed on Nang Yuan; bring a reusable bottle

This trip is worth it if you want to snorkel or try a first dive. It is a long day of boats for a short beach stop otherwise, and if your choice is one trip, pick Ang Thong.

Koh Taen (Koh Tan)

Koh Taen sits about 20 minutes by boat off Samui’s south coast and is the island’s easy half-day snorkelling option, often combined with neighbouring Koh Madsum. It is the right call for families who want a boat trip without a full day at sea.

Big Buddha (Wat Phra Yai)

The golden seated Buddha, over 12 metres tall, sits on the small island of Koh Fan, joined to the north coast by a causeway. Entry is free, and you should cover your shoulders and knees. It was built in 1972, so it is a striking modern landmark rather than an ancient temple. Give it 30 minutes, ideally late in the afternoon when the light is softer.

Hin Ta and Hin Yai

The Grandfather and Grandmother rocks at the southern end of Lamai are free to see, with small parking fees charged by local landowners. They are a 15-minute stop if you are passing. They are not worth a special journey across the island, and the narrow path to the rocks gets crowded when tour vans arrive.

6. Where to Eat

Two anchors are worth planning around rather than leaving to chance.

• Fisherman’s Village walking street, Bophut: every Friday from around 17:00 to 22:30, the main road closes to traffic and fills with food and craft stalls. Arrive by 18:00 to walk the full length before the crowds peak around 19:30. Entry is free
• Hua Thanon fish market: the village supplies much of the island’s seafood, and an early visit shows a side of Samui that most resort guests never see

Beyond those, the honest rule is to eat where you are staying. Chaweng and Lamai have the widest choice on foot, Bophut has the best evening atmosphere, and in Maenam you will be driving for variety.

7. Worth It / Skip It

✅ Worth it if

• You can travel between January and April, when the sea is calm and the weather settled
• You want a family beach holiday with calm, shallow water, and you book Choeng Mon or Bophut
• You want one outstanding day trip: Ang Thong is genuinely spectacular
• You like a lively main strip without Bangkok-level chaos, and you book Lamai

⛔ Skip it if

• Your only dates are in November. Ang Thong is normally closed and the east coast often flies red flags. Consider the Andaman side instead, starting with our Phuket guide
• You want quiet but have booked Chaweng. Move to Choeng Mon, ten minutes away
• You are planning to learn to ride a scooter on holiday. Hire a car or use taxis
• You want an untouched desert island. Samui is a developed resort island; the quieter scenery is offshore at Ang Thong, or on Koh Phi Phi across the peninsula

8. What It Costs

Accommodation varies too widely across Samui to give a reliable single figure, from simple guesthouses in Maenam to premium resorts in Choeng Mon, so compare live rates for your exact dates. The fixed costs worth knowing before you budget are these:

• Ang Thong park fee: 300 THB per foreign adult, normally included in tour prices
• Koh Nang Yuan entry: 250 THB per adult
• Big Buddha, Hin Ta and Hin Yai, Fisherman’s Village walking street: free
• Helmet fine if you ride without one: 2,000 THB per person

The biggest hidden cost is distance. Staying on a quiet beach and taking taxis to Chaweng every night adds up fast, which is the strongest reason to pick a base that matches the holiday you actually want.

FAQ

Which Koh Samui beach is best for families?

Choeng Mon is the best beach for families with young children. Its bay is calm and shallow, so small children can paddle safely, and it is only about ten minutes from Chaweng’s shops and restaurants. Bophut is a good second choice with better evening dining.

Is Chaweng or Lamai better?

Choose Chaweng for the widest choice of hotels, food and nightlife, and Lamai for the same kind of beach with fewer people and usually lower prices. Couples and budget travellers tend to be happier in Lamai.

What is the best month to visit Koh Samui?

February is usually the best month, as it is typically the driest of the year. The wider window of January to April is reliably good. Avoid mid October to early December, the island’s wettest period.

Is Ang Thong Marine Park worth it from Koh Samui?

Yes, it is the most rewarding day trip from the island, provided you go outside the November to mid December closure. The viewpoint climb is steep, so it suits reasonably fit adults and older children better than toddlers.

Can tourists rent a scooter on Koh Samui?

Yes, but only legally with a home-country motorcycle licence and an International Driving Permit with the motorcycle endorsement. Both rider and passenger must wear helmets, and the fine for not doing so is 2,000 THB per person.

How do you get to Koh Samui from Bangkok?

The quickest way is a Bangkok Airways flight from Suvarnabhumi, which takes about 1 hour 15 minutes. The cheaper alternative is to reach Surat Thani on the mainland and take a ferry from Donsak pier, around 45 minutes by catamaran.

Our Verdict

Here is what we would book. Families: Choeng Mon, with one Ang Thong day and one Friday evening in Fisherman’s Village. Couples: Bophut for the dinners, or Lamai if you want a livelier strip. Groups and first-timers on a short stay: Chaweng, accepting the noise. Long, quiet stays on a budget: Maenam with a hired car. Whoever you are, travel between January and April if you can, and do not book a beach week in November.
