Chaweng Beach, Koh Samui: north, central and Chaweng Noi, from a local crew
By the Endless Summer crew · · 9 min read
Chaweng Beach on Koh Samui is the island's busiest stretch of sand: several kilometres of pale sand, the longest beach on the island, running down the east coast with hotels, restaurants and the main nightlife behind it. It is really three beaches in one, and which part you pick changes your holiday more than most people expect.
Our free hotel pickup covers Chaweng, and our half-day trip anchors in the coves just south of it, so this guide covers what we would tell a friend: how north Chaweng, central Chaweng and Chaweng Noi differ, when the sea is good for swimming and when it isn't, where to find quiet, what the beach is like after dark, and the easy day trips from here.
Where is Chaweng Beach on Koh Samui?
Chaweng Beach is on Koh Samui's east coast, facing east across the Gulf of Thailand, between the headland below Choeng Mon to the north and Lamai to the south. Samui airport is close, typically a short taxi ride, which is one reason so many first-time visitors stay here.
A beach road runs behind the sand for most of its length, lined with shops, restaurants and hotel entrances, and lanes off it lead down to the beach. The island's ring road runs further inland. Behind the middle of town is Chaweng Lake, and the Central shopping centre sits just off the main strip.
Because Chaweng faces east, you get sunrise over the sea here, not sunset. The sun goes down behind the island, which matters if a sunset over the water is on your list.
North Chaweng, central Chaweng or Chaweng Noi: which part is best?
The best part of Chaweng Beach depends on what you want from it: the north end for space and calm, the middle for activity and swimming, Chaweng Noi for a quieter, smaller bay.
| Section | Character | Water | Suits |
|---|---|---|---|
| North Chaweng | Wider sand, fewer people, resorts rather than a strip | Very shallow over a reef offshore; best near high tide | Small children paddling, walkers, light sleepers |
| Central Chaweng | Busiest stretch, loungers, vendors, water sports, nightlife | Sandy and gently shelving; deep enough to swim a little way out | People who want everything close |
| Chaweng Noi | Smaller separate bay past a rocky point, mostly resorts | Calmer bay; good swimming on calm days | Couples, families wanting quiet |
North Chaweng. At the northern end the water stays shallow a long way out, with a reef further off and the small island of Koh Matlang offshore. At low tide it can be too shallow to swim properly, and some people wade out across the flats towards the island. If you try that, wear reef shoes, watch for sea urchins, and check a tide table so you are not caught by the water coming back in.
Central Chaweng. This is the Chaweng in most photographs: a long run of sand in front of the beachfront venues with music and the bigger hotels, with banana boats, jet skis and kayaks for hire. The bottom is sandy and slopes gently, so on a calm day it is easy swimming. Keep clear of the lanes that the jet skis use, and if you hire one, photograph it before you set off.
Chaweng Noi. South of the main beach, past a rocky point, is a smaller bay with its own stretch of sand, backed mostly by resorts. There is no nightlife strip behind it, the vendors thin out, and it feels like a different place from central Chaweng, though it is only a few minutes away.
Is Chaweng Beach good for swimming?
Chaweng Beach is good for swimming for much of the year: the sand is soft underfoot, there is little rock or weed on the main stretch, and in calm weather the sea is flat and warm. The exception is the north-east monsoon, from about mid-October to mid-December, and it is a real exception.
The east coast takes the swell first. The north coast is sometimes easier, but a strong north-easterly makes it rough too; the crew decide on the day. For a beach day, that means checking the sea yourself before you go. In a rough spell Chaweng gets waves breaking on the beach, strong currents and, often, red flags.
- A red flag means no swimming. It applies to strong swimmers too.
- Lifeguards are not on every stretch. Do not assume someone is watching.
- If a current pulls you out, don't fight it head-on. Swim parallel to the beach until you are out of it, then come back in, and raise an arm to signal for help.
- Don't swim at night, and don't swim alone on an empty stretch.
The settled months are roughly late December to April, plus June to August, when Chaweng is usually calm enough for children to paddle and adults to swim out. For what the wet weeks are actually like, see our guide to the Koh Samui rainy season.
Where to find a quiet part of Chaweng
The quietest Chaweng is early morning, at either end. Before the loungers go out, the beach belongs to walkers, joggers and resort staff raking the sand, and with the sun coming up over the sea it is the best time of day here.
For the rest of the day, head north of the central strip or south to Chaweng Noi. You can walk most of the main beach on the sand; from one end to the other is well over an hour at an easy pace, so a long morning walk is a good way to decide which part you like. In the heat of the afternoon, bring water and shade, because the sand reflects a lot of sun.
What Chaweng Beach is like at night
Chaweng Beach at night is the busiest place on Samui, but only in the middle. Central Chaweng is the island's main nightlife area: beach clubs with music and fire shows on the sand, and the lanes behind the beach road, around Soi Green Mango, stay loud until late. Restaurants along the beach road are busy all evening.
Walk ten minutes north or south and it goes quiet quickly. The north end and Chaweng Noi are mostly hotels and restaurants after dark, and you can hear the sea. Taxis are easy to find in central Chaweng early in the evening and harder after midnight, so sort out your ride back if you are staying further out.
If you would rather spend an evening on the water, there is no sunset over the sea from Chaweng. Our Sunset Cruise runs 16:00 to about 19:30 on the north coast, out to the open water off Bang Po, where the sun goes down over the sea. It is never a party boat: soft drinks, a swim stop and light bites on deck, back in time for dinner.
Getting around from Chaweng
Taxis wait along the strip; most quote a fixed fare, so agree it before you get in. In the November rains, low-lying roads around Chaweng can flood for a few hours after a heavy downpour, so allow extra time. Lamai is the next big beach to the south, and the Big Buddha at Bangrak is a short drive north.
Day trips from Chaweng: the coves next door and a morning on the boat
The best easy day trip from Chaweng is just down the road. South of Chaweng Noi, the ring road climbs over the headland towards Lamai past two small boulder coves with often the clearest water on this coast: Coral Cove first, then Silver Beach (Crystal Bay). Both are a short taxi ride from central Chaweng and have the snorkelling that Chaweng's long sandy beach doesn't. Go early; they fill by late morning.
Those two coves are also where our half-day trip stops to snorkel and swim: Silver Beach or Coral Cove, chosen on the day by what guests prefer and what the sea allows. The free hotel pickup covers Chaweng; pickups run between 07:00 and 08:15 depending on your area, and the crew confirm your time the day before. The Thai teak cruiser boards at 09:00 at Petcharat Marina in Bangrak or Hansar Samui Resort in Bophut, passes the Big Buddha on Koh Faan, anchors at the cove with snorkelling gear for everyone and lunch on board, and is back alongside by 14:00. It runs Monday to Friday for up to 15 guests.
The trade-off: you see the coves when the boat is there, not at dawn, and on the roughest monsoon days the crew may move or cancel the trip. For a wider look at the island's sand, our guide to the best beaches on Koh Samui covers the rest of the coast briefly.
Questions people ask us
- Is Chaweng Beach good for swimming?
- Yes, for most of the year. The sand is soft, the bottom slopes gently and the sea is usually calm from late December to April and from June to August. From mid-October to mid-December the north-east monsoon brings waves and strong currents to the east coast, and red flags often fly. A red flag means no swimming.
- Which part of Chaweng Beach is the best?
- It depends what you want. North Chaweng is quieter and very shallow over a reef, good for paddling near high tide. Central Chaweng is the busy strip with water sports, nightlife and the easiest swimming. Chaweng Noi, past the rocks to the south, is a smaller, calmer bay with mostly resorts behind it.
- What is Chaweng Noi like?
- Chaweng Noi is a smaller bay just south of the main Chaweng beach, separated by a rocky point. It is backed mostly by resorts, has fewer vendors and no nightlife strip, and is calmer than central Chaweng. It suits couples and families who want Chaweng's restaurants within a short ride but a quieter beach.
- What is Chaweng Beach like at night?
- Central Chaweng is Samui's main nightlife area, with beachfront venues with music, fire shows and busy lanes behind the beach road that stay loud until late. The north end and Chaweng Noi are much quieter after dark. Taxis are easy early in the evening and scarcer after midnight. Don't swim at night.
- Is Chaweng Beach good for families?
- Yes, in the calm months from late December to April and June to August. The north end is shallow and quiet, good for small children paddling near high tide, and Chaweng Noi is a calmer bay with fewer vendors. Central Chaweng is busier, with jet skis offshore and music late at night, so pick your hotel's position carefully. Stay out of the water when red flags fly.
- Do your boat trips pick up from Chaweng?
- Yes. Free hotel pickup covers Chaweng on every trip, within the 07:00–08:15 window for the half-day trip and 14:00–15:15 for the Sunset Cruise, confirmed the day before. The half-day trip costs ฿2,900 per adult and the Sunset Cruise ฿2,500 per adult.
