Koh Samui
The island the team lives on: beaches, areas, getting around, what's worth it.
Getting to Samui by air (USM airport)
Koh Samui Airport (IATA: USM) is a privately owned, open-air, garden-style airport in the northeast near Bophut/Bang Rak, built and operated by Bangkok Airways, which owns the airport and runs most flights. The Bangkok (Suvarnabhumi)–Samui hop takes roughly 1h10. Bangkok Airways also flies from Phuket, Chiang Mai, and other regional points; some other carriers code-share or run limited routes. Because Bangkok Airways dominates, fares run notably higher than to mainland airports. Budget travellers often fly into Surat Thani (URT) on the mainland, then connect by bus and ferry. USM is small, walkable, and tarmac buggies ferry passengers to the terminal.
Getting to Samui by ferry
Samui has no bridge; access is by air or sea. Car and passenger ferries run from the mainland, mostly from Donsak pier (Surat Thani province), roughly a 1.5-hour crossing. Main operators: Raja Ferry and Seatran Ferry (vehicle ferries from Donsak), and Lomprayah (high-speed catamaran, popular for the Samui–Pha Ngan–Tao chain). Combined bus-and-ferry tickets from Surat Thani town, the train station, or Surat Thani Airport are common and sold as one package. Samui's main arrival piers are Nathon (west coast, Seatran/passenger), Lipa Noi (Raja vehicle ferries), and Bang Rak/Big Buddha pier (speedboats to Pha Ngan/Tao). Sea can be rough in monsoon season.
Island geography and orientation
Koh Samui is one of Thailand's largest islands (commonly cited as second after Phuket), about 228 sq km, in the Gulf of Thailand off Surat Thani province. A mountainous, jungled interior is ringed by a coastal road (Route 4169) roughly 50 km around, taking about 1.5 hours to drive non-stop. The busy east coast (Chaweng, Lamai) holds the main tourist beaches and nightlife; the calmer north (Bophut, Maenam, Bang Rak, Choeng Mon) suits families and quieter stays; the west (Nathon, Lipa Noi, Taling Ngam) is the ferry and sunset side, less developed. Samui sits near sister islands Koh Pha Ngan and Koh Tao, both reachable by ferry.
Chaweng — the main beach and nightlife hub
Chaweng, on the east coast, is Samui's largest and busiest beach town: a long white-sand bay with calm, swimmable water (a reef breaks the waves), backed by a dense strip of hotels, malls, restaurants, bars, and nightclubs. It is the island's nightlife centre and the most commercial, walkable area, with the highest concentration of shops and services. Expect crowds, traffic on the single main road, and street touts. Chaweng Noi, just south over a headland, is a smaller, quieter cove. A good base for first-timers and partygoers who want everything in walking distance; less ideal for those seeking calm.
Lamai — second beach town, more relaxed
Lamai, south of Chaweng on the east coast, is Samui's second-biggest beach town: a long sandy bay with a more laid-back, slightly cheaper feel than Chaweng, though it still has bars and a small nightlife strip. The southern end of the beach can have rocks and stronger surf in season. Nearby are the famous Hin Ta and Hin Yai ("Grandfather and Grandmother") rock formations — naturally shaped rocks resembling genitalia, a long-running photo stop. Lamai has a popular walking-street night market on set evenings. It draws a mix of couples, long-stayers, and budget-to-midrange travellers.
Bophut and Fisherman's Village
Bophut, on the north coast, centres on Fisherman's Village — a restored old Chinese-Thai trading quarter of narrow lanes lined with wooden shophouses now holding boutique restaurants, bars, galleries, and shops. It is one of the island's most charming, atmospheric quarters, popular for dining and a relaxed evening stroll. The beach is quieter and more upscale than Chaweng/Lamai, with calm water and sunset views toward Koh Pha Ngan. Fisherman's Village hosts a well-known Walking Street night market on certain evenings, with food stalls, crafts, and live music. Bophut suits couples, foodies, and travellers wanting character over party energy.
Maenam, Choeng Mon, and Bang Rak
These north-coast areas are quieter alternatives to the east-coast strips. Maenam is a long, shallow, undeveloped beach popular with families, long-stayers, and budget travellers; it has a relaxed village and a weekly walking street. Choeng Mon, on the northeast tip near the airport, is a small, calm, protected bay with upscale resorts and a sheltered swimming beach, good for families. Bang Rak ("Big Buddha Beach") sits beside the Big Buddha temple and its pier; the water is shallower and the beach more functional than scenic, but it is convenient for the airport and speedboats to Koh Pha Ngan and Koh Tao.
Nathon, Lipa Noi, and Taling Ngam (west coast)
The west coast is Samui's quiet, local, sunset-facing side. Nathon is the island's main town and administrative centre, with the principal passenger ferry pier, the immigration office, banks, markets, and government offices — useful for errands and authentic Thai food, but not a beach-holiday base. Lipa Noi has a wide, shallow, calm beach and is a key vehicle-ferry arrival point; its flat sand and gentle water suit families and sunset watchers. Taling Ngam, on the southwest, is a secluded stretch of luxury resorts with hillside sea views toward the Five Islands (Koh Si Koh Ha). The west sees fewer tourists and less nightlife overall.
Getting around: songthaew, taxis, and Grab reality
Public transport is informal. Songthaews (shared pickup trucks with bench seats) run fixed loops along the ring road in daylight; you flag one down, ride, and pay on exit — cheap for locals' routes but tourists are often overcharged, so confirm the fare before boarding and carry small notes. Metered taxis exist but frequently refuse the meter and quote inflated flat rates; agree the price firmly in advance. Grab operates on Samui but coverage and driver availability are patchier and pricier than in Bangkok, especially late at night or in remote areas; Bolt is sometimes available too. Many visitors rely on hotel transfers or pre-booked private cars.
Motorbike rental — safety, licence, insurance, scams
Scooter rental is cheap and everywhere, but Samui's roads are genuinely dangerous: heavy traffic, steep hills, sand and rain on tarmac, and inexperienced tourist riders make motorbike crashes a leading cause of foreign injury and death. Legally you need a valid motorcycle licence (an International Driving Permit endorsed for motorcycles, or a Thai licence); a car licence does not cover bikes. Helmets are mandatory by law and police checkpoints fine riders without them. Travel insurance commonly voids motorbike claims if you lack the correct licence or weren't wearing a helmet — check your policy. Common scams: shops keeping your passport as deposit (leave a cash deposit or a copy instead), and inflated "damage" claims on return — photograph the bike thoroughly before riding.
Ang Thong National Marine Park
Ang Thong (Mu Ko Ang Thong) is an archipelago of about 42 islands northwest of Samui, protected as a national marine park and famous for jagged karst cliffs, hidden lagoons, beaches, and viewpoints. It is reached only by organised day-trip boat (speedboat or slower big boat) from Samui, typically a full day. Highlights include the emerald inland saltwater lagoon (Thale Nai) on Koh Mae Ko, reached by a steep climb to a viewpoint, kayaking among the cliffs, and snorkelling. The park charges a national-park entrance fee and routinely closes for part of the monsoon season (commonly around November to mid-December) when seas are unsafe — it is not open year-round.
Big Buddha and Wat Plai Laem
Wat Phra Yai ("Big Buddha"), on a small islet linked by causeway at the northeast tip near the airport, is a roughly 12-metre golden seated Buddha visible to arriving boats and an iconic landmark, with stairs up to the statue, a viewpoint, and stalls below. A short ride away is Wat Plai Laem, a vivid modern Thai-Chinese temple complex on a lake featuring a striking white 18-armed image of Guanyin (the goddess of mercy) and a large laughing Budai. Both are active temples — dress modestly (shoulders and knees covered) and remove shoes where required. Entry is generally free; donations welcomed.
Na Muang waterfalls and Secret Buddha Garden
Na Muang has two waterfalls in the island's lush interior: Na Muang 1 is a wide, easily reached cascade with a pool you can swim in; Na Muang 2 is taller and needs a steeper jungle walk (or a paid "safari" truck/transfer). They flow best in and just after the rainy season and can drop to a trickle in the dry months. The Secret Buddha Garden (Magic Garden / Tar Nim) is a hilltop sculpture garden high in the mountains, built by a local fruit farmer, scattered with statues of deities, animals, and humans among streams and jungle — reached via a rough, steep road usually best tackled by 4x4 or as part of a tour, not a standard scooter.
Day trips: Koh Pha Ngan and Koh Tao
Samui is the gateway to two neighbour islands. Koh Pha Ngan, a short speedboat hop north, is famous for the Full Moon Party at Haad Rin beach — a massive all-night beach party held roughly monthly around the full moon (with occasional extra Half Moon and Black Moon events); by day Pha Ngan also offers quiet beaches, waterfalls, and yoga retreats in the north. Koh Tao, further out by ferry, is one of the world's busiest and most affordable scuba-diving training centres, with shallow reefs ideal for beginner certification and abundant dive schools. Both are doable as day trips, but Koh Tao especially rewards an overnight stay.
Beaches by vibe
For nightlife and everything-in-walking-distance: Chaweng. For a slightly calmer beach-town buzz: Lamai. For charm, dining, and sunsets: Bophut/Fisherman's Village. For families and calm, shallow water: Choeng Mon, Maenam, Lipa Noi, and Bang Rak. For seclusion and luxury sea views: Taling Ngam and the southwest. For a local-town feel rather than a holiday beach: Nathon. East-coast beaches (Chaweng, Lamai) catch the morning sun and the main swell; north and west beaches are generally calmer and better for sunsets. Many bays have offshore reefs that flatten the water but can mean shallow, rocky entries at low tide.
Food and night markets
Samui's food spans cheap, excellent Thai street food to high-end resort dining. Southern Thai cooking is bold and spicy — expect fiery curries, fresh Gulf seafood, and dishes like khao mok (Thai biryani). The cheapest, most authentic eating is at local markets and roadside stalls, especially in Nathon and Maenam. Rotating evening walking-street night markets are a core experience: Fisherman's Village (Bophut), Lamai, Maenam, Chaweng, and Nathon each have their own market night, with food stalls, fresh fruit, grilled seafood, and crafts. Tap water is not safe to drink — use bottled or filtered water, which is cheap and everywhere. Vegetarian and Western food is widely available in tourist areas.
Weather and best time to visit
Samui sits in the Gulf of Thailand and runs on a different rhythm to Phuket and the Andaman coast. The driest, sunniest stretch is roughly January–April; March–May is the hottest. The island's main rainy season is the northeast monsoon, roughly late October to December, with November typically the wettest — heavy downpours, rougher seas, and possible ferry/tour disruption (this is the key counter-intuitive point: Samui's worst weather is when much of Thailand is at its best). September–October can also see rain. There is a shorter wetter spell around June. Temperatures stay warm year-round (high 20s to low 30s°C); rain often comes as intense bursts rather than all-day grey.
Money, ATMs, and cards
The currency is the Thai baht (THB). Cash still rules for markets, street food, songthaews, and small shops, though hotels, larger restaurants, and tour operators increasingly take cards. ATMs are plentiful in tourist areas but Thai banks charge a fixed foreign-card withdrawal fee per transaction (on top of your home bank's fees), so withdraw larger amounts less often. Many places add a surcharge for credit-card payment. Currency-exchange booths (e.g. in Chaweng and Nathon) often give better rates than airport or hotel exchange. The QR-based PromptPay/mobile-payment system is common locally but generally needs a Thai bank account. Keep small notes for songthaews and markets.
SIM cards and connectivity
Thailand has strong, cheap mobile data. The main networks are AIS and the merged True/TrueMove H–dtac group (still sold under both the True and dtac brands), all with good 4G/5G coverage across populated Samui; signal can drop in the mountainous interior and on boat crossings. Tourist prepaid SIMs (and eSIMs) with generous data allowances are sold at the airport, convenience stores, and phone shops; buying a physical SIM requires showing your passport for registration. Wi-Fi is near-universal in hotels, cafes, and restaurants, though speeds vary. A local SIM or eSIM is strongly recommended for maps, ride apps, translation, and messaging. Airport SIM kiosks are convenient but tend to cost more than in-town shops.
Health and medical care
Samui has solid private healthcare for an island its size. Bangkok Hospital Samui (near Chaweng) is the main international-standard private hospital, with English-speaking staff, emergency care, and direct-billing arrangements with many travel insurers; Thai International Hospital and Samui International Hospital (both Chaweng area) and a public hospital in Nathon are alternatives. Pharmacies are widespread and sell many medications over the counter. Travel insurance is strongly advised — private care is good but expensive, and serious cases may need evacuation to Bangkok. Common health issues are sunburn, dehydration, stomach upsets, motorbike injuries, and, in the rainy season, mosquito-borne illness (dengue) — use repellent. Thailand's emergency numbers: 1669 for ambulance, 191 for police.
Safety and common scams
Samui is generally safe for visitors, with low violent crime, but petty issues and tourist-targeted scams exist. The biggest real danger is road accidents (motorbikes). Watch for: jet-ski operators claiming pre-existing damage to extract payment; motorbike rental "damage" disputes and passport-as-deposit demands; taxi/songthaew overcharging and meter refusals; inflated tour or bar tabs; and drink spiking or theft at large parties (notably the Full Moon Party on Koh Pha Ngan). Drugs are illegal and police stings around party islands are common. Keep valuables in hotel safes, beware strong rip currents and jellyfish in some seasons, and avoid leaving drinks unattended. Tourist police can be reached on 1155.
Temple and cultural etiquette
Thailand is predominantly Theravada Buddhist and reveres the monarchy; both deserve respect. At temples, cover shoulders and knees, remove shoes before entering buildings, and never point your feet at a Buddha image or person — feet are considered the lowest, dirtiest part of the body, the head the most sacred (don't touch people's heads). Women should never touch a monk or hand things directly to one. The standard greeting is the wai (palms pressed together with a slight bow). Public anger or loud confrontation causes loss of face and rarely helps; calm and a smile go far. Speaking disrespectfully of the King or royal family is a serious criminal offence (lese-majeste). Dress modestly away from the beach.
