🇹🇭Koh Samui

Thailand's second-biggest island, and its most polished — coconut groves giving way to resort strips, a golden Big Buddha watching over the northeast coast, and an easy, no-boat-required flight straight in.

Money & what things cost

Samui is more built-up than Krabi or Koh Lanta — cards are widely accepted at resorts, restaurants, and dive shops. You'll still want cash for songthaews, beach vendors, and the Fisherman's Village and Lamai night markets.

What locals earn

Average monthly salary (Koh Samui, tourism)≈ ฿14,000–18,500 ($400–530)the island's economy is almost entirely resorts, dive tourism, and hospitality
Minimum wage≈ ฿370/day ($11)provincial rate, similar to Phuket's
Why this matters: A resort night can cost what a housekeeper here earns in a week — worth keeping in mind when tipping. Samui's higher-than-mainland prices reflect a genuinely more developed tourist economy, not just a markup for foreigners; most residents work directly or indirectly in hospitality.

Getting around

From the airport
Samui International (USM) is small, palm-thatched, and privately owned by Bangkok Airways — which is why flights and the fixed-rate taxi desk both run pricier than elsewhere in Thailand. Expect ฿400–700 for a taxi into Chaweng or Bophut.
Songthaews
Open-air shared trucks loop the ring road connecting all the main beaches — flag one down, confirm the fare (often ฿30–150 depending on distance), and hop off wherever.
Scooter rental
The best way to explore beyond your beach — viewpoints, waterfalls, and the Big Buddha are all spread around the island. Roads are decent but hilly in places; wear a helmet.
Taxis & ride apps
Metered taxis are rare — most quote a flat, often steep, fare. Grab has patchy but growing coverage in the main tourist zones and is usually cheaper and more transparent.
Ferries
Regular ferries link Samui to Koh Phangan (Full Moon Party island, about 30–45 minutes away) and Koh Tao, plus the mainland at Surat Thani for onward bus/train travel.

Neighborhoods to stay in

Chaweng
The island's main strip — longest beach, densest nightlife and restaurants, most convenient base.
Fisherman's Village (Bophut)
Boutique and low-key, with a atmospheric Friday walking street and a slower pace than Chaweng.
Lamai
Second-biggest beach town, cheaper than Chaweng, mellower but still lively at night.
Maenam / Bang Rak
Quiet, near the airport and the mainland ferry pier, popular with longer-stay visitors.
Choeng Mon
Small, upscale, and calm in the island's northeast — the luxury-resort corner.

Tipping & etiquette

Tipping: Not expected anywhere, though common at resorts and dive shops given the tourism-driven economy — 10% or rounding up at restaurants is well received.
  • Dress modestly at temples like Wat Phra Yai and Wat Plai Laem: shoulders and knees covered, shoes off before entering.
  • The head is sacred and feet are lowly: don't touch anyone's head, don't point your feet at people or Buddha images.
  • Topless or nude sunbathing isn't culturally accepted, even on the more touristy beaches.
  • Respect flag warnings and lifeguard advice, especially during the October–December monsoon swells.
  • If you go to a Full Moon Party on nearby Koh Phangan, book your return ferry in advance — they sell out.

Safety & common scams

Generally very safe, with the everyday risks being practical rather than criminal: scooter accidents among inexperienced riders, rip currents in rougher months, and Samui's well-known unmetered-taxi overcharging. Petty theft is uncommon but not unheard of on busy beaches.

Scams to know

  • Fixed 'taxi mafia' fares — Samui's taxis are famously unmetered and pricey; agree the price first or use Grab where it's available.
  • Jet-ski damage claims — photograph every angle of the vehicle before riding, as with Phuket.
  • Scooter rental damage disputes — video the bike on pickup, including small existing scratches.
  • Overpriced 'VIP' ferry or Full Moon Party packages sold on the beach — compare a couple of operators before booking.

Emergency numbers: 1155 tourist police (English-speaking) · 191 police · 1669 ambulance

Phone & internet

Grab an AIS or TrueMove tourist SIM at the airport or a 7-Eleven (roughly ฿300–500 for 8–15 days), or set up an eSIM before flying. Coverage is strong across the developed east coast, with some dead spots inland and on outer islands.

First-timer FAQs

Do I need a visa?

Most Western passports currently get 60 days visa-exempt on arrival. Rules shift — check the official Thai immigration site before booking.

Chaweng, Lamai, or Bophut — where should I stay?

Chaweng for nightlife and convenience, Lamai for a calmer but still lively alternative, and Fisherman's Village in Bophut if you'd rather have boutique charm than a party scene.

Should I fly or take the ferry to Samui?

Flying direct into Samui Airport is fastest but pricier; flying into Surat Thani on the mainland and taking a ferry across is the budget route and adds about 2–3 hours.

Is the rainy season really different here than the rest of Thailand?

Yes — Samui's peak rain falls October–December, opposite the west-coast islands like Phuket and Krabi. Plan around that if you're combining destinations.

How many days do I need?

Four to five days covers the main beaches, Big Buddha, Fisherman's Village, and a day trip to Koh Phangan or Ang Thong Marine Park comfortably.
