Lamai sits on the east coast of Koh Samui, just south of Chaweng — about 15–20 minutes' drive from Chaweng, or 25–30 minutes from Samui Airport. The beach runs roughly 4 km of fine, pale sand with fairly clear water, and what a lot of people like is that the surf is gentler than at Chaweng, so it's easier to swim. Behind the beach, Lamai Road gathers a decent mix of hotels, restaurants, massage shops, and bars — but it's noticeably less dense than Chaweng. In short, you still have food and things to do within walking distance, but with a quieter, more private feel. It suits families, couples, or anyone who actually wants to switch off.
Who Lamai Beach suits — compared to Chaweng
Lots of people go back and forth between staying at Chaweng or Lamai. The easiest way to decide is to ask yourself what kind of trip you want. Lamai isn't so quiet that it's dull, but it isn't as busy and hectic as Chaweng either — it's a happy middle ground for a lot of travelers.
- Traveling with family / young kids — gentler surf, shallow water that deepens gradually, easier to swim with peace of mind, and a calmer atmosphere overall.
- Couples / honeymooners — the southern end near Hin Ta Hin Yai has big granite boulders scattered in the water, forming pretty little coves that feel private.
- Want to relax but still have food and things to do — Lamai Road has restaurants, live-music bars, and a night market to wander in the evening, just less crowded than Chaweng.
- Hardcore party people — if you're after pool parties, beach clubs, and clubs going late and packed, Chaweng delivers more. Lamai has nightlife, but on a smaller scale.
Which part of Lamai to stay in
The northern end of the beach is the quietest and most private · the middle is the hub for restaurants and bars and an easy walk to the night market · the southern end near Hin Ta Hin Yai has pretty rocky coves and clear water, great for photos and swimming — but you'll want a car or motorbike since it's a fair way from the restaurant strip.

Swimming and activities at Lamai Beach
Lamai's main draw is easy swimming. From the middle of the beach up to the north end the water is fairly calm — good for a swim and for paddleboarding. The southern stretch with the boulders is shallow with rocks underwater, so watch your step, but you get lovely views. Along the beach there are a few spots renting sun loungers and offering light water activities, though there are fewer of them and they're more spread out than at Chaweng.
- Swimming / lounging on the sand — free; some places charge around 100–150 THB for a lounger, or it's free if you order drinks.
- Stand-up paddleboarding (SUP) / kayaking — rentals run about 300–500 THB per hour; mornings, when the water is calmest, are best.
- Beachside massage — Thai or foot massage under an umbrella on the sand, around 300–400 THB per hour, with a nice sea breeze.
- Snorkeling / island tours — you can book trips to Ang Thong Marine Park or snorkeling tours from the tour shops on Lamai Road; prices depend on the program and the season.
Sea safety — straight talk
The sea around Samui changes with the season. During the Gulf of Thailand monsoon, roughly October–December, the wind and waves pick up and the water gets murkier, so snorkeling visibility drops and some days tours don't run. Before you swim or head out on a tour, always check the forecast and listen to the operator's warnings. Wear a life jacket whenever you're on a boat, and watch for submerged rocks along the southern end of the beach.
Lamai Night Market
In the evening, Lamai has a night market for grazing and strolling. The everyday Lamai Night Market is in the middle of Lamai town, around opposite the McDonald's on Lamai Beach Road, and runs most nights from about 5 PM onward. There's street food, souvenirs, clothes, and live music on some nights. The food is varied and a lot cheaper than the beachfront restaurants, making it a wallet-friendly place to try local dishes.
- What you'll find to eat — som tam, grilled chicken, pad thai, southern-style curry-over-rice, grilled seafood, roti, and Samui-style banana pancakes, roughly 40–120 THB a plate.
- Souvenirs — T-shirts, keychains, wood carvings, and island handicrafts; there's some room to haggle.
- Atmosphere — shared communal tables, easy to walk around, not so packed you're squeezed in, close to the beach and Lamai's café area.
About the Sunday market — check before you go
Lamai used to have a big, well-known Sunday Night Market, but the original closed during COVID and hasn't fully returned. For now there's the everyday night market and smaller-scale versions in its place. If you're coming specifically to walk the big Sunday market, it's worth checking the current status and latest location with your hotel or a local page first so you're not disappointed.
Hin Ta Hin Yai — the island's iconic rock pair, right nearby
About 2 km from the southern end of Lamai Beach, near the Hua Thanon fishing village, is Hin Ta Hin Yai (Grandfather and Grandmother Rocks) — Hin Ta (grandfather) and Hin Yai (grandmother). These are natural granite formations carved by wind and waves into shapes resembling male and female genitalia, and they've become a landmark most visitors to Samui stop to photograph.
Local legend tells of an elderly couple who set off by boat to ask for a young woman's hand in marriage on behalf of their son, only to hit a storm that sank the boat and drowned them at sea — and so they became the pair of rocks at the end of Lamai Beach to this day. The walkway down to the rocks is lined on both sides with souvenir stalls, fresh coconut water, and snacks.
- Admission — free (with parking and shops all around).
- Opening hours — roughly 8:30 AM–6:30 PM (some days later); late morning or late afternoon is best to avoid the midday sun.
- Good to know — the little beach by the rocks is full of boulders and not really for swimming; you can dip your feet in the pools. Some parts of the path are slippery, so wear shoes with good grip.
What else to see around Lamai Beach
The upside of Lamai is that it sits right in the middle of several of the island's southern sights, so a short drive lets you hit a few places in one day.
Overlap Stone (Hin Lat viewpoint)
A huge boulder balanced on a hill behind Lamai Beach. A short climb gets you a view looking down over the beach and sea — best for photos in the morning or evening when the sun isn't harsh.
Wat Lamai / Wat Khunaram
Wat Lamai is close to Lamai town, while Wat Khunaram — home to a famous mummified monk — is a short drive further out. Worth a stop to pay respects and see the local temple architecture.
Hua Thanon fishing village
An old Muslim fishing village near Hin Ta Hin Yai, with a fresh market, brightly painted fishing boats, and southern Thai / halal food to try. A glimpse of real island life.
Where to eat around Lamai Beach
Around Lamai you'll find everything from beachfront seafood to Thai–Western restaurants to street food in the market. Below are the popular, easy-to-find spots that are genuinely open. Prices are approximate ranges and shift with the season and high season.
Lamai Night Market
The best value eating in the area. Opens around 5 PM with som tam, grilled chicken, southern dishes, grilled seafood, and island desserts — local prices and a genuine market atmosphere.
Lamai beachfront seafood
Seafood places set tables right on the sand in the middle of the beach. Order prawns, crab, fish, and grilled squid fresh, eaten to the sound of the waves. The setting is great but pricier than the market — confirm the price per kilo clearly before you order.
Southern Thai food around Hua Thanon
Near the Hua Thanon fishing village you'll find punchy southern Thai and halal restaurants — gaeng tai pla, khua kling, khao yam, and fresh seafood at modest prices, with proper southern flavors.
Lamai Road cafés and restaurants
All along Lamai Road there's a mix of cafés, Thai–Western restaurants, pizza, and live-music bars. Take your pick — good for an easy meal or an afternoon coffee.
Best time to visit Lamai Beach + getting around
Koh Samui's high season is roughly December–April: clear skies, a beautiful sea, and the best swimming — but it's busier and hotel prices climb. May–September is still fine for a trip and accommodation is cheaper, while October–December is the Gulf of Thailand monsoon, with more rain and stronger surf, and some days you can't swim or run sea tours. Room and tour prices on the island swing quite a bit with the season, so comparing several options and booking ahead in high season works out better value.
Getting around Lamai and driving on the island
Within Lamai town you can walk to the shops and market, but to reach Hin Ta Hin Yai, Overlap Stone, or Hua Thanon you'll need transport. Motorbike rental runs about 200–300 THB/day, or a car about 800–1,500 THB/day · many roads on the island are steep, winding, and dark at night, so drive slowly, wear a helmet, and avoid driving when it's raining and the roads are slick · if you'd rather not drive, you can use taxis or hired cars on the island, but always agree the price before you get in.
