Best beaches in Koh Samui: a guide to choosing where to stay

There is no single best beach on Koh Samui, but there is a best fit for each person. If you want restaurants and nightlife, look at Chaweng or Lamai. If you want a calm bay with dining on the sand, look at Bophut, Maenam or Choeng Mon. The Tourism Authority of Thailand (TAT) describes Chaweng and Lamai as the bustling beaches and Bophut, Maenam and Choeng Mon as the more peaceful and laid-back ones.

This guide to the best beaches in Koh Samui is for a reader who is deciding where to stay or, further down the road, where to buy. It covers the main beaches one by one: how each feels, who it suits, what sits nearby and how the seasons affect it. The Koh Samui beaches that official sources describe in detail are few, and we say so where a description is thin rather than fill the gap. Distances to The Astra Samui come from the developer.

Koh Samui beaches at a glance

• Bophut: a long bay on the north coast facing Koh Phangan, with Fisherman’s Village behind it. Peaceful by TAT’s grouping. The Astra Samui is here.
• Chaweng: on the east coast, with the largest choice of shops and restaurants in our areas guide. Bustling.
• Lamai: a beach town on the south-east coast. Bustling.
• Maenam: on the north coast, west of Bophut. Peaceful.
• Choeng Mon: on the north-east, close to the airport. Peaceful.
• Bang Rak: the beach around the Big Buddha temple, on the north-east.
• Lipa Noi and Taling Ngam: the west and south-west coast, away from the main resort strips.
• Rain, not heat, is what separates the months. October to December are the wettest, February the driest.

How to choose a beach on Koh Samui

Start with how you will use the place, not with a photo of the sand. A week’s holiday and a home you live in for months need different answers. Five questions help.

1. How much activity do you want after dark? Restaurants, bars and a late street are a plus for some people and a reason to move for others.
2. How often will you fly? Samui International Airport is in the north-east, so the distance to it varies a lot from beach to beach.
3. What do you need nearby? A supermarket, a pharmacy and a hospital matter more over a few months than a few days.
4. When will you be here? Beaches behave differently in the wet and dry months, and the island is quieter in the wettest weeks.
5. Do you want to walk to the beach, or are you happy to drive? Many apartments and villas on Koh Samui sit a short distance back from the sand, which usually means quieter nights and lower noise.

TAT gives one useful split. In its newsroom article of 19 May 2021, it separates the bustling Chaweng and Lamai beaches from the more peaceful and laid-back Bophut, Mae Nam and Choeng Mon beaches. We use that grouping below, and we mark where TAT is silent. The island is Thailand’s second-largest island, after Phuket, with an area of about 228.7 km², so every beach is within a drive of the others, but a ring road with traffic makes the trip longer than the map suggests.

For a comparison that goes beyond sand and covers hospitals, schools and shops by area, read our guide on where to live in Koh Samui.

Bophut Beach

Bophut Beach is a long, gentle bay on the north coast of Koh Samui, and it looks across the water to Koh Phangan. TAT groups it with the peaceful, laid-back beaches. It is not known as a surf beach. People swim, walk the edge of the bay at sunset and eat dinner at tables on the sand. Check conditions on the day, because waves change with the season.

What sets Bophut apart is Fisherman’s Village, the old centre of the area. TAT’s destination page notes that Bo Phut has converted old Chinese shophouses, which today are mostly restaurants, cafés, small hotels and shops along one narrow street. On Friday evenings the street becomes a walking street market, which is the busiest night of the week.

Who it suits: people who want a quiet beach during the day and a real choice of restaurants in the evening, without Chaweng’s late-night strip. Couples, remote workers and families who value everyday services nearby often like it. It suits less well if you want a beach with big surf or a beach with nothing built around it.

Our guide to living in Bophut follows an ordinary week there, including hospitals, schools and the airport.

Chaweng Beach

Chaweng is on the east coast, and TAT places it among the bustling beaches. TAT’s destination page lists Chaweng and Lamai as beaches for sunbathing and swimming through the day. Central Samui, a department store and mall, is on Chaweng Beach Road, as mapped on OpenStreetMap, and our areas guide gives road distances from Chaweng to the airport and to hospitals.

Who it suits: first-time visitors who want everything within a short ride, people who like an evening out, and anyone who prefers to be in the middle of things. It is a poor fit if you are looking for a calm road, since traffic and nightlife are part of daily life here.

A practical point. Shoreline conditions can change, and TAT has published a notice about a wrecked fishing boat on Chaweng in 2019, when red flags were raised and swimmers were kept out of the water. That is history, not a current warning, but it shows the habit to adopt on any Koh Samui beach: look at the flag before you go in.

According to the developer, Chaweng Beach is 6.3 km from The Astra Samui.

Lamai Beach

Lamai is on the south-east coast and is a beach town in its own right. TAT counts it with Chaweng as bustling. It has its own shops and services, and it feels more self-contained than the beaches on the north coast.

TAT’s newsroom names two sights near Lamai. The Grandpa and Grandma Rocks are a couple of kilometres south of the beach. The Mummified Monk at Wat Khunaram is about six kilometres west. The same article mentions WeGreen, a cultural park and vegetable farm, close to the rocks. Those distances are TAT’s, from 2018, so confirm them with a map before you plan a day around them.

Who it suits: travellers who want a livelier beach but a slightly less packed one than Chaweng, and people who do not mind being further from the airport. If you will fly often, the extra drive matters: our areas guide puts Lamai the furthest of six areas from the airport.

Maenam Beach

Maenam, also written Mae Nam, is on the north coast, west of Bophut. TAT groups it with the peaceful, laid-back beaches, and it also looks across to Koh Phangan. TAT’s text gives no further description, so we do not add more than its position and its grouping.

Who it suits: people who put quiet first and are happy to drive to Bophut for larger shops and a hospital. A longer ride to the airport than from the north-east is the trade-off. Varsovia Estate has an office in Maenam, so we know the area well and can show it to you.

Choeng Mon Beach

Choeng Mon is on the north-east of the island, near the airport, and TAT lists it among the more peaceful beaches. According to the developer, Choeng Mon Beach is 8.3 km from The Astra Samui, and Samui International Airport is 7.3 km from the project.

Who it suits: people who want a short airport transfer and a quieter beach, and are content with fewer large shops close by.

Bang Rak and Big Buddha Beach

Bang Rak is the area around the Big Buddha temple, Wat Phra Yai, on the north-east. TAT explains that Big Buddha Beach is named after the temple, which stands on Ko Fan off the north-eastern corner of the island and is reached by a causeway. A golden Buddha about 12 metres tall is visible from several kilometres away, according to TAT.

TAT does not describe the beach’s pace, so we do not put it in the busy or peaceful group. What we can say is that it is a separate beach from Bophut. Its position in the north-east is close to the airport, which is practical for short stays. Lomprayah lists ferries to Koh Phangan and Koh Tao from Bangrak Pier, so check current timetables with the operator.

Lipa Noi, Taling Ngam and the west coast

The west and south-west of Koh Samui are the parts of the island that feel least developed. Lipa Noi lies on the west coast, and Taling Ngam on the south-west. TAT’s destination page lists Taling Ngam among the beautiful beaches of Koh Samui, but we found no official description of Lipa Noi, so we do not describe its sand or water, and the same goes for Taling Ngam beyond that listing.

Here is what is safe to say. A west-facing coast sees the sun set over the sea, which the north and east coasts do not. These beaches are away from the main resort strips, so you should expect fewer restaurants and shops on the beach itself and longer drives to hospitals and the airport. That suits people who want seclusion and do not mind driving.

If one of these beaches is on your list, stay a night or two before you commit and test the practical points: the drive to a supermarket, a hospital and the airport, the road at night and the noise level. Our areas guide gives measured road distances for six other areas, which is a good yardstick for comparing.

Beaches compared

Pace follows the TAT newsroom article of 19 May 2021. Where TAT is silent, we write “not rated”. Positions are general, and the right choice depends on the street, not only the beach.

Seasons and wind on Koh Samui beaches

Koh Samui is warm all year, so the season that matters on the beach is mostly about rain. The Land Development Department (LDD), using the Thai Meteorological Department (TMD) classification, divides Thailand into three seasons. The rainy season with the south-west monsoon runs from mid May to mid October, and the winter season with the north-east monsoon from mid October to mid February. The summer season runs from mid February to mid May.

Koh Samui is on the east coast of southern Thailand, which is an exception. According to the LDD, abundant rain on that coast lasts until the end of the year, and November is the wettest month. TMD’s Koh Samui station agrees: in its 1991 to 2020 averages, October to December are the wettest months and February is the driest, at 64.3 mm. Our full month-by-month reading is in the weather guide.

For choosing a beach this has two consequences. First, if you plan to be on the island in November or December, expect showers and plan time off the sand. Second, wind and sea conditions change from one beach to another and from one season to the next. We know of no official table that ranks Koh Samui beaches by wave or wind, so we do not rank them. Ask the people who run a beach restaurant what the water has been like this week, look at the flags, and treat red as closed.

Reading beach descriptions with care

Most of what is written about Koh Samui beaches comes from hotel pages, blogs and booking sites. They are useful for ideas, but they rarely agree. One page calls a beach quiet because it was visited at seven in the morning, another calls the same beach lively because it was visited on a Friday night. Three habits help you read them.

• Look for the date. A beach changes after a new resort opens, after a storm or after a road is widened. A description from several years ago may no longer fit.
• Look for the hour and the day. Ask what time of day and which day the writer was there. Fisherman’s Village on a Friday is a different place from the same street on a Tuesday.
• Separate the sand from the surroundings. Whether a beach is good for swimming is one question. Whether the road behind it is quiet, whether there is a pharmacy nearby and how long it takes to reach the airport are others, and they matter more once you live here.

This is why we lean on TAT’s grouping for pace and on the developer’s figures for distances to The Astra Samui, and why we say “not rated” when there is no official description. It is also why a few days on the ground are worth more than a long evening of reading.

Which beach for which kind of stay

A short holiday, a few months each year and a permanent move pull in different directions. These are our suggestions, not rules.

• A first holiday of a week or two: Chaweng or Lamai if you want a lot to do, Bophut if you want a calmer evening. Both are easy to reach by taxi or scooter.
• Several months on the island: the quieter beaches, Bophut, Maenam and Choeng Mon, fit people who need a working routine, such as remote workers. Check the internet connection of the place you rent, not only the beach.
• Living here for most of the year: weigh hospitals, schools and the airport above the sand. A beach a short drive away is a small cost if everything else is close.
• Buying an apartment you will also rent out: be careful with beach-first thinking. Rules for short stays are strict, and our guide to the short-term rental rules on Koh Samui explains what is allowed. Rental is a possibility, not something we can promise.

Beaches and The Astra Samui

The Astra Samui is a low-rise, resort-style condominium in Bophut, on the north coast of Koh Samui. According to the developer, Bophut Beach is about 300 m from the project, and Fisherman’s Village is 850 m. That puts it a short way back from the sand rather than on the market street, which is usually a quieter position than the beachfront itself.

The project also has its own water: a 70 m tropical lagoon pool inside tropical gardens, for days when you do not want to go to the sea. If you like the idea of both, a beach in the morning and a pool at home, Bophut gives you that. Chaweng Beach is 6.3 km and Choeng Mon Beach 8.3 km from the project, according to the developer, so the other main beaches are within a drive.

Completion is planned for Q4 2028, and prices start from THB 3,700,000 (about €98,000, NBP average rate of 23 October 2026). Read the Bophut location page for a map of the surroundings, browse the apartments, and compare the island’s areas in our guides to living in Bophut and the weather by month.

A visit before you decide

A beach looks different on a Sunday afternoon and on a Tuesday morning, in March and in November. If a beach is a deciding factor, spend at least a few days on it, at different times of day. Walk to the water from where you would live. Eat at the nearby restaurants. Listen to the street at ten at night. Our guide to a property viewing trip to Koh Samui has a day-by-day plan.

Varsovia Estate is the sales agent for The Astra Samui, and we have an office on Koh Samui. If you want to talk through the beaches, the areas and what suits you, book a call with our team.
