Koh Samui beaches, one by one
Chaweng Beach
Chaweng is the best-known beach in Koh Samui: some 7 km of white sand on the east coast, and the beating heart of the island.
📍 Open in Google Maps
Our take:
Chaweng suits travelers who don’t want to give anything up, but it turns noisy after dark. Book a room toward the north or south end of the beach: you get the quiet and still stay close to everything.
Who it's for: anyone who wants nightlife, convenience and services on tap.
What to see nearby: the beach clubs, Chaweng lake and the night market.

Lamai Beach
Lamai is the second-largest beach in Koh Samui, right below Chaweng, framed by the Hin Ta and Hin Yai granite boulders.
📍 Open in Google Maps
Our take:
This is the beach our team suggests most often to families and couples: restaurants and street life, without the Chaweng crush. The middle stretch is the pick for swimming.
Who it's for: families, couples and calmer travelers.
What to see nearby: the Hin Ta and Hin Yai rocks and Lamai market.

Bophut Beach and Fisherman's Village
Bophut, on the north coast of Koh Samui, pairs a beach facing Koh Phangan with the old Fisherman’s Village.
📍 Open in Google Maps
Our take:
Bophut is our team’s pick for evenings: you eat with your feet almost in the sand, and the mood stays easy and stylish. It is not the best stretch for swimming, but the setting alone earns the stay.
Who it's for: couples, food lovers, anyone after character.
What to see nearby: Fisherman's Village and the Friday Night Market.
🏨 Where to stay near Bophut
Maenam Beach
Maenam is a long, quiet beach on the north coast of Koh Samui, a favorite with travelers watching their budget, with a wide view across to Koh Phangan.
📍 Open in Google Maps
Our take:
This is where you go to switch off for real: long walks at sunset, cheap beachfront bungalows and hardly a soul around. One thing to watch is the tide, which at times pulls the water a long way out.
Who it's for: anyone after downtime, space and fair prices.
What to see nearby: Maenam village and the bars along the sand.
🏨 Where to stay near Maenam
Choeng Mon Beach
Choeng Mon is a run of small bays on the northeastern tip of Koh Samui, with calm, shallow water.
📍 Open in Google Maps
Our take:
Still sea, soft sand and a small-scale feel: the right call for families and couples who want calm without straying far from the airport or from Chaweng.
Who it's for: families with young children, and couples.
What to see nearby: the string of quiet bays and the Big Buddha.

Silver Beach (Crystal Bay)
Silver Beach is a small, striking bay between Chaweng and Lamai, rated one of the best places to snorkel in Koh Samui.
📍 Open in Google Maps
Our take:
Mid-morning is the moment, when the light turns the water bright blue; with a mask and fins you will spot colorful fish among the rocks. It is small, so it fills up fast.
Who it's for: keen snorkelers, and couples.
What to see nearby: the rocky seabed and its tropical fish.
🏨 Where to stay near Crystal Bay
Lipa Noi Beach
Lipa Noi is a broad, silent beach on the west coast of Koh Samui, known for its sunsets over the Gulf of Thailand.
📍 Open in Google Maps
Our take:
The place to close the day: at sunset the sky catches fire and the sand stays almost empty. The shallow water makes it work for families too.
Who it's for: sunset watchers, families, anyone chasing stillness.
What to see nearby: the seafood restaurants and the ferry pier for Don Sak.
Taling Ngam Beach
Taling Ngam is one of the most secluded beaches in Koh Samui, in the southwest of the island, between wild greenery and a handful of resorts.
📍 Open in Google Maps
Our take:
You come here to drop off the map: barely any tourists, a wild feel and long views toward the neighboring islands. You will need your own transport, since it sits well away from the main centers.
Who it's for: couples and travelers who want privacy, full stop.
What to see nearby: the views over the archipelago, and the sunsets.
Thongson Bay Beach
Thongson Bay is a small hidden bay on the northeastern tip of Koh Samui, next to Choeng Mon, tucked between rocks and away from the crowds.
📍 Open in Google Maps
Our take:
One of the stillest and most private bays on the island: a sheltered crescent of sand, very few visitors and flat water. We point there anyone who wants a corner to themselves while staying minutes from Choeng Mon and the airport.
Who it's for: couples, and anyone hunting for quiet and privacy.
What to see nearby: Choeng Mon and the Big Buddha, both close by.
Coral Cove
Coral Cove is a small rocky inlet between Chaweng and Lamai, on the east coast of Koh Samui, and one of the island’s favorite spots to snorkel.
📍 Open in Google Maps
Our take:
The rocky bottom near the shore holds coral and bright fish, and a mask picks them out at once. It is small and no use for long swims off the sand, but for snorkeling it ranks among the best you can reach without a boat.
Who it's for: keen snorkelers, and couples.
What to see nearby: Silver Beach and the viewpoints along the Chaweng-Lamai road.
Practical Tips for Koh Samui Beaches
- Pick your coast by pace: the east coast (Chaweng, Lamai) is the liveliest; the north coast (Bophut, Maenam) is more laid-back; the west coast (Lipa Noi, Taling Ngam) is the stillest, and the best for sunsets.
- Always check the tides: beaches such as Maenam lose a lot of water at certain hours, so plan your swim around them.
- Bring reef shoes for snorkeling: the bottom at Silver Beach and Coral Cove is rocky.
- Reach the small beaches early: Silver Beach packs out fast, and the morning light is the best you will get.
- Use Grab or a rental car to move between beaches: the Ring Road circles the whole island, but the distances add up.
Mistakes to Avoid
Booking Chaweng and expecting calm
It is the busiest beach on the island. For calm, Maenam, Lipa Noi or Choeng Mon are the better call.
Expecting fine sand everywhere
Maenam and Bophut have coarser sand. For the classic white sand, go to Chaweng or Lamai.
Underestimating the sun
The glare off the water is fierce. Use high-factor sunscreen and drink often.
Leaving belongings unattended
Even on the calmest beaches, never leave valuables on your lounger while you swim.
Snorkeling at the peak of the rainy season
Between October and November underwater visibility drops sharply, above all on the east coast.

FAQ
Which is the most beautiful beach in Koh Samui?
It depends what you are after. For services, bars and a long run of white sand, Chaweng is the most complete choice. For a calmer mood while keeping restaurants and evening life, Lamai is a good middle ground. For character and sunsets, Bophut with its Fisherman's Village is hard to beat. The "most beautiful beach" is the one that matches the pace of your trip.
Which is the best beach in Koh Samui for families?
Choeng Mon, Lipa Noi and Lamai work best, with calm, shallow water for young children and services close by. Choeng Mon in particular is compact and quiet, near the airport and the Big Buddha.
Where is the best snorkeling in Koh Samui?
The best spots on the island are Silver Beach (Crystal Bay) and Coral Cove, between Chaweng and Lamai, with clear water and rocky bottoms. For snorkeling that really stands out, though, it is worth giving a full day to a boat excursion out to the neighboring islands, where there is far more to see underwater.
Can you swim at Koh Samui beaches all year round?
For most of the year yes, above all from December to April, when the sea is flat. In the rainy season, between October and November, the water can turn choppy and visibility drops, particularly on the east coast. Check the conditions before you go in.
Which coast of Koh Samui should you choose?
The east coast (Chaweng and Lamai) is the most developed, with services and nightlife: the classic call for a first visit. The north coast (Bophut, Maenam, Choeng Mon) is calmer and suits families and couples. The west coast (Lipa Noi, Taling Ngam) is the most silent and hands you the finest sunsets, but it sits far from the main centers.
In Short
The beaches of Koh Samui cover every need: Chaweng for services and nightlife, Lamai and Choeng Mon for families, Bophut for character, Maenam for a small budget, Silver Beach for snorkeling and Lipa Noi for sunsets. The rule of thumb is to choose your coast by the pace you want, and to check the tides every time.
