Koh Samui Travel Guide

Samui's settlements and beaches line the ring road around the island; the interior is mountainous, with steeper and in places narrow roads. Chaweng is in the east, Lamai in the south-east, Bophut–Mae Nam in the north, Nathon in the west and Taling Ngam in the south-west. The airport is in the north-east; the main car ferries arrive at the western piers. So how you arrive changes the cost of your choice of area.

"You can ride round the island in two hours" isn't a travel plan. With stops, traffic, rain, roadworks and mountain detours, it's a full loop day. Rather than circling four coasts every day of your holiday, set up one main base, one island tour and one boat day.

Another difference is Samui's climate. Phuket and Krabi are on the Andaman Sea; Samui is in the Gulf of Thailand. Don't expect the same sea conditions on both coasts in the same month. In late autumn to the end of the year especially, rain and waves can noticeably affect a Samui plan.

Chaweng is the long east coast with the most restaurants, shopping, nightlife and transport. The northern, central and southern ends of the beach aren't the same; read reviews about the flight path, shallows, late-night music and pedestrian access. Easy for a first car-free visit; the central section can be tiring for anyone wanting quiet.

Bophut/Fisherman's Village, with its old Chinese shopfronts, restaurants and evening walks, is a balanced base for couples/families. It can get busy on market nights, and the beach's swimming character changes with the season/tide. Bangrak/Big Buddha is close to the airport and Koh Phangan boats; some sections are far from a classic beach feel because of pier/boat traffic.

Mae Nam offers a calmer rhythm on the north coast, suited to long stays and family holidays. Restaurants may be scattered; check the hotel's real distance to the main road and the beach. Choeng Mon gives a quiet but more enclosed holiday, with a small bay, resorts and proximity to the airport.

Lamai is the second main centre, smaller and more relaxed than Chaweng but with restaurant/nightlife options. The beach's character changes from end to end. It combines easily with Hin Ta–Hin Yai and a southern island route. Don't confuse it with Rawai; that's in Phuket.

Taling Ngam–Lipa Noi is strong for western sunsets, quiet resorts and ferry access. It's far from the airport, Chaweng and most north-eastern events. If you want to leave the hotel and eat in a different neighbourhood every night, transfer costs climb; if you want a retreat, it's an advantage. Nathon is a functional pier/town, not a main beach base for most travellers.

Samui International Airport (USM) is in the north-east of the island. From the small, open-air-style terminal, distances to Chaweng, Bophut, Bangrak and Choeng Mon are relatively short; Lamai and the west and south coasts are further. The airport's official site lists taxi/limousine/transfer, car hire and local songthaew options.

Although a hotel transfer looks expensive, it can be predictable for a night arrival, children, lots of luggage or a far-off Taling Ngam/Lipa Noi location. At the taxi/limousine counter there are fixed quotes by area; in the Grab app you can see the designated pickup area and available cars. Read whether airport/special-zone conditions are included in the app price.

A songthaew can be cheap, but it doesn't work like a fixed fast shuttle. You may need to get out to the main road, wait with your luggage and transfer depending on the vehicle's route. For a first-timer arriving at night, compare the hotel car; by day, with light luggage and a hotel on the main road, the songthaew option.

Samui flights can be more expensive than the Bangkok road + ferry combination; when comparing totals, add the car from Surat Thani airport/city to Donsak, the waiting, the ferry and the last transfer from the Samui pier to the hotel. A cheap ticket isn't always a cheap and short journey.

Car/passenger ferries run from the Donsak piers on the mainland to Nathon or Lipa Noi on Samui's west side; the operator and the pier for each sailing change. Companies such as Seatran and Raja don't use the same terminal or the same Samui pier. Don't read your ticket just as "Surat Thani–Samui", but by its departure terminal and arrival pier.

Surat Thani Airport, the railway station or the city centre aren't Donsak itself. A combined bus + ferry ticket can make the transfer easier; if you're buying separately, make sure the land vehicle will reach the right terminal in time. Because of the risk of missing the last ferry, leave a wide margin between separate tickets.

Fast boats towards Koh Phangan/Koh Tao may often use different Samui piers such as Bangrak, Mae Nam or Nathon. If you're arriving from the mainland and continuing to another island the same day, you may need an on-island pier transfer. Check the operator, boat type, luggage, weather cancellation and exact pier on the voucher.

Ferry times change with the season, maintenance and the sea; don't treat a PDF published years ago as a definitive timetable. The official operator's booking screen and same-day announcements are decisive. Planning a long boat connection from Koh Tao on the same day as your return flight is a high risk on a separate ticket.

There's no rail on Samui. Local songthaews collect passengers in set directions on the ring road but shouldn't be read like a timetabled municipal bus. Say which beach you're going to and agree the per-person fare before getting in; at night, for special detours or with few passengers, the price may change. It's normal for the vehicle not to go down your hotel's side road.

Taxis, hotel cars and Grab are the main alternatives. App coverage/car numbers vary by coast and time; don't leave your night return from a remote western resort until the last minute. With a street taxi, agree the total fare and waiting in writing. For a day's island tour, a car with driver can be more predictable than four separate taxis.

Hiring a car can make sense for families and a scattered route. Responsibility for driving on the left, sudden scooter movements, inland hills, flooding and night lighting passes to you. Ask about hotel parking. Don't drive on days when you plan to drink or are tired.

Scooters are common on the island, but TAT also stresses that motorcycle accidents are a serious risk. Don't ride without a licence for the right motorcycle class and a 1949 IDP, a helmet, experience and policy coverage. The renter handing over the key isn't proof of competence. At hand-over, ask for a video, tyre/brake/light checks and a deposit option instead of your passport.

Big Buddha and Wat Plai Laem are sacred stops close to each other in the north-east. Cover shoulders/knees and follow the signs on shoes and photography. Rather than snapping photos quickly between tour buses, explore without blocking the donation/worship areas. Combine them with a Bangrak/Bophut day.

The Hin Ta–Hin Yai natural rock formation south of Lamai is a short stop; it isn't worth crossing the island just for it, so add it to a Lamai/southern route. The amount of water at the Na Muang waterfalls changes with the season. Don't climb on wet rock, in unsuitable shoes or in restricted areas for a photo. If you see animal shows/elephant tours around the waterfalls, don't automatically accept the package.

Inland destinations such as the Secret Buddha Garden can have steep roads; whether a saloon car/scooter is suitable depends on the weather. Discuss a plan with your driver as one route: the west coast for sunset, the southern/central hills for views and Mae Nam–Bophut for food.

The Fisherman's Village walking market may grow on certain weekly nights; as the day and scale can change, confirm with your hotel or local official announcements. Even on a non-market evening, Bophut's restaurants and beach walk are lively. Nathon's sunset and everyday market show a different, local face from the resort strip.

Mu Ko Ang Thong National Marine Park, with karst islands, a viewpoint, kayaking and coves, is Samui's signature day trip. Open-sea and park access may be restricted by season/weather. The climb to the viewpoint can be slippery and hot; take your shoes, water and fitness into account. Ask whether the park fee, kayaking and hotel pickup are included.

Koh Phangan isn't just the Full Moon Party; its northern bays and island stays are a separate holiday. If you're crossing from Samui for a day trip to a market/party, sort out the return boat, the pier and night-time safety in advance. On party nights capacity and prices may differ from normal days.

Koh Tao is strong for diving/snorkelling, but as a day trip from Samui it can be a long boat day. An early start, many hours at sea and little time in the water don't suit everyone. If you want to dive, staying a few nights on Koh Tao gives flexibility for training and weather; verify instructor/centre certification and insurance cover.

When choosing a boat, look at passenger capacity, shade, toilets, life jackets, licence, insurance and cancellation policy before speed. Don't hide back/neck problems, pregnancy, small children or motion sickness. Don't tie your last sea day to the same date as an international flight.

On Samui tables, local fish/shellfish, coconut, Gulf squid and southern Thailand's hot, herby curries stand out. Try gaeng som, khua kling, crab coconut curry, seafood grilled with turmeric and khanom jeen. Coconut caramel or a local coconut dessert can be a more island-specific finish than a resort cocktail.

For seafood, see the day's price, the weight and the cooking charge before ordering. "Local catch" doesn't always mean a sustainable catch from around Samui; ask about the species and source. With allergies, remember that shrimp paste/fish sauce is hidden in curries and dips.

The Michelin Guide 2026 covers Samui and Surat Thani. On Samui, two Bib Gourmands — Baan Suan Lung Khai and Jun Hom — were verified in the current selection; there are also Selected restaurants. Don't mistake the Michelin logo for a star: being listed, a Bib and a star are different statuses. On the cards we've only used wording we verified.

Samui is in the Gulf of Thailand. Usually late December–April is drier and more comfortable; the summer months can still be visited with periodic downpours; late October–December is when the heaviest rain, waves and flood risk of the north-east monsoon can be seen. The exact boundary changes every year. Although TAT's Surat Thani page highlights April–November for island visits, you need to check local TMD data month by month.

This difference can make Samui an alternative in summer months that look rainy in Phuket/Krabi; but it's no guarantee that "Samui is definitely dry in summer". The late-September and October transition varies from year to year. Hotel cancellation terms and the boat plan matter more than historical averages.

TMD's Koh Samui station provides current weather, weekly forecasts and historical statistics. On the morning of a boat trip, look not only at your phone app but at TMD marine warnings and the operator's decision. After rain, inland waterfall roads and standing water in low areas can affect transport.

Samui can be more expensive than mainland Thai cities: island logistics, taxis, resort menus and imported products make a difference. Add airport/ferry transfers and the cost of a car every evening when comparing accommodation. Cards are widespread at resorts and contemporary businesses; carry THB cash for songthaews, markets, small restaurants and boats. A PromptPay QR doesn't mean a foreign banking app will work.

Vapes/e-cigarettes are banned in Thailand. Since 2025 the cannabis flower has been a controlled product requiring a medical prescription; the appearance of sales on a tourist street is no proof of legal freedom. Don't carry the product on a ferry/plane. The drinking age in Thailand is 20; don't ride a scooter at night.

Common mistakes: copying Phuket's rainfall calendar to Samui, thinking USM and Nathon are close, not adding the Donsak transfer to a cheap mainland flight, assuming Fisherman's Village has a market of the same size every night, and leaving the Full Moon Party return boat unplanned. On the island, an empty weather day isn't a luxury but a safety margin.
