Koh Samui sells itself as a pool with an island attached, and for many people that is the right purchase. The trouble is that the list of things to do in Koh Samui has been copied from brochure to brochure for thirty years — the Big Buddha, the rocks that look like genitals, a mummified monk in sunglasses — and nobody says which are worth the songthaew fare. Some are; several exist because a tour desk needs to sell you something before checkout.
I’m from Bangkok, my family has been coming here since Nathon was the only town with a bank, and this is the list as I’d give a friend: a verdict on each, the 2026 foreigner price, and how to get there.
The short version: book one boat trip and make it Ang Thong; see the Big Buddha and Wat Plai Laem before nine; do Bophut’s Friday walking street early; spend one sunset on the empty west coast; and treat the jet skis and the elephant camps as what they are. Where you sleep decides how much of this is on your doorstep; our Where to Stay in Koh Samui guide handles that, and Bangkok to Koh Samui covers the getting-here.
How this list works
Each entry gets a verdict — Do it, Do it, with a caveat, or Skip it — the foreigner price where there is one (Thailand dual-prices most sights; Samui adds a tour-desk mark-up), and the way to get there. Getting around: shared songthaews on the ring road are ฿50–100 a hop between Chaweng, Lamai, Bophut and Nathon, fare agreed before you climb in, thinning out after 8pm. Grab is ฿150–300 across the island. A scooter is ฿200–300 a day and legally needs a motorcycle licence or an IDP with the motorcycle category; the checkpoints at both ends of Chaweng know this, and so does your insurer. Prices are the ones in our Thailand Price Index. Nothing here was comped.

Things to do in Koh Samui that are worth the hype
Ang Thong Marine Park — Do it; if you take one boat trip, this is it. Forty-two limestone islands an hour west of Nathon: the Emerald Lake on Koh Mae Ko, the viewpoint on Koh Wua Ta Lap everybody’s photo is taken from, kayaking under cliffs that drop straight into the sea. A big boat is ฿1,200–1,500, a speedboat ฿1,800–2,500, and nearly every operator collects the ฿300 park fee on top, in cash, on the pier. The park closes from roughly 1 November to mid-December. Compare Ang Thong tours by group size and whether the viewpoint climb and kayaking are included; the cheapest big boats skip one or both.
Big Buddha, Wat Phra Yai — Do it, free, before 9am. A twelve-metre seated Buddha on its own islet off Bangrak, joined by a causeway, in sight of the runway: naga steps, a view along the north coast, and a working temple where my mother still makes merit every visit. By ten the car park is coaches and the steps are a queue. Shoulders and knees covered; our temple etiquette guide covers the rest. Wat Plai Laem — Do it, on the same morning. Five minutes away, the eighteen-armed Guanyin and the fat laughing Buddha sit on a lake so they reflect. Free; fish food is ฿20 and the children will want it. The two together are an hour, which is the correct dose.
Fisherman’s Village Friday walking street — Do it, with a caveat. Bophut’s old shophouse street closes to traffic on Friday evenings and fills with grilled squid, mango sticky rice, ฿60 cocktails in plastic cups and a reasonable amount of tat. By half past seven it is shoulder-to-shoulder in a lane two metres wide, so arrive at five, eat while the stalls are fresh, be on a beanbag by seven. Free. Bophut sunset bars — Do it, any night but Friday: the beachfront faces north-west, so the sun goes down behind Koh Phangan with beanbags on the sand and a ฿250–400 cocktail. Coco Tam’s is the famous one; the bars either side pour the same sunset for less.
Lamai Sunday night market — Do it. The smaller, cheaper, more Thai version of the Friday one, in Lamai’s centre from about 5pm: better food, fewer elephant trousers, ฿40–80 a plate. Swim off Lamai’s south end first, the better half of the beach.
Na Muang waterfalls — Do it; number 2, not number 1. Na Muang 1 is the roadside one with the car park and the elephant camps beside it. Na Muang 2 is a half-hour uphill walk from there, an 80-metre drop into a pool you can swim in, free apart from ฿20 scooter or ฿60 car parking. From February to April it is a damp rock; go in the wet half of the year. The camps at the foot of the trail sell rides and “bathing” photos, and the answer to both is no.
Secret Buddha Garden, the Tarnim magic garden — Do it, with a caveat. A durian farmer spent his seventies filling a mountain stream with concrete deities, musicians and himself, and it is genuinely odd and genuinely lovely. ฿80 entry. The caveat is the road, a steep concrete track off Route 4169 that eats scooters in rain. Take a car, or a 4×4 jungle safari (฿1,500–2,000) that bundles it with the viewpoints and the waterfall; opt out of any elephant stop.
The mummified monk at Wat Khunaram — Do it, ten minutes. Luang Pho Daeng died meditating in 1973 and asked to be displayed if his body didn’t decay. It didn’t, so there he sits in a glass case on the ring road near Na Muang, in the sunglasses the temple added when his eyes dried out. Free, quietly moving, a Thai attitude to death you won’t get from a beach. Cover up; it is a living temple.
Lipa Noi and Taling Ngam sunset — Do it. The east coast gets a sunrise nobody is awake for; the west coast gets the sunset, over the Five Islands, off shallow, calm water the resorts on the other side would kill for. Lipa Noi’s beach is public and mostly empty, and a beer at a shack bar is ฿80–100. Free, forty minutes from Chaweng, the best hour of the island’s day.
A Thai cooking class — Do it. Half a day, ฿1,500–2,500, ideally starting at a market and ending with you eating four or five dishes including a curry paste you pounded yourself. Ask for a southern dish — sour orange curry, a proper massaman — over the pad thai default; our southern Thai food guide tells you what to look for. Compare Koh Samui cooking classes by market visit and dish count; those two things separate the good ones.
Kayaking or SUP at Choeng Mon — Do it. The calmest, clearest bay on the north-east corner, with a sandbar to Koh Fan Noi you can walk at low tide. Boards and kayaks from the beach are ฿300–500 an hour; go before ten when the water is glass.
Samui Elephant Sanctuary — Do it, with a caveat; no-riding only. Samui has one properly observation-only sanctuary and several camps that borrowed the word. The real one is ฿3,000 for a half day with lunch: you walk beside the elephants, feed them, and keep your hands off them in the water. That is the price of doing it right. Filter for no-riding, no-bathing sanctuaries and read the newest reviews for “ride” or “bathe”; our ethical elephant sanctuaries guide explains why those two words are the whole test.
Overrated things to do in Koh Samui — and what to do instead
Hin Ta Hin Yai — Five minutes, then leave. Grandfather and Grandmother Rocks: two granite formations south of Lamai that resemble, respectively, a penis and a vulva, and have supported a souvenir gauntlet for forty years on that basis. Free, ฿20 to park. Look, laugh, buy a coconut, go; the coast either side is prettier and empty.
Koh Tan and Koh Madsum, “Pig Island” — Do it, with a caveat, and know what the pigs are. A longtail from Thong Krut, ฿1,300–1,800 shared with lunch and a snorkel stop. The snorkelling off Koh Tan is fine — soft coral, sergeant majors, a metre more visibility than Chaweng. The pigs on Madsum are a beach attraction fed by tourists on a schedule: neither wild nor suffering, not a reason to go. If it’s real reef you’re after, spend the money on Koh Tao instead. Compare the longtail and speedboat versions; the longtail is slower and better.
Muay thai at Chaweng stadium — Do it only with adjusted expectations. The tourist card: ฿1,500 standard, ฿2,000 ringside, ฿3,000 for a drink and a better plastic chair. Some real fights, some choreography, a ladyboy bout, at a price that buys a week of the genuine article in Bangkok. Fun as a night out; not the sport. Haggle at the door, or try the smaller Phetchbuncha stadium in Lamai.
The Jungle Club viewpoint — Do it, with a caveat. A restaurant on the hillside above Chaweng Noi with the view every drone shot of the island is imitating. Entry is free, a drink ฿150–300, the food average at ฿300–500. The road is steeper than the Secret Buddha’s; ring ahead and they send a 4×4 down. One sundowner, not dinner.
Ladyboy cabaret — Skip it, or go with your eyes open. Starz on the Chaweng strip is ฿250 with your first drink, three shows a night, forty-five minutes of lip-synced Whitney and sequins. The performers are talented; the show is the one Pattaya and Phuket run, and the after-show photo costs a ฿100 tip. A laugh if you go; nothing about Samui missed if you don’t.
Jet skis — Skip it, no caveat. ฿1,500–2,000 for thirty minutes on Chaweng or Lamai, and the operator holds your passport. When you bring it back a scratch has appeared that wasn’t in the photos you should have taken, and the bill is ฿20,000 with a friend in uniform nearby. It is the oldest scam on the coast; our Thailand scams guide explains how it plays out. Kayak at Choeng Mon instead.
Ark Bar pool party — Know what you’re buying. Chaweng’s daily pool party, 2pm to 2am: ฿300 minimum spend gets a sunbed, ฿500 a head the pool, drinks ฿180–300. It is exactly what it looks like — a loud, sunburnt, well-run beach club with a DJ — and if that is your holiday, it delivers. If you came for the island, it could be anywhere.
Golf at Santiburi — Do it, if that’s you. The island’s only eighteen holes, in the hills above Maenam with the Gulf below most tees: ฿5,300–5,800 walk-in with the mandatory cart and caddie, about ฿3,500 before seven. Expensive for Thailand, cheap for a resort island, and the caddies are the best company on the course.
Worth it if you have an extra day or two
Koh Phangan — the ferry from Bangrak or Maenam is thirty minutes and about ฿300, and the island is more than the party: Thong Nai Pan, the yoga coast at Sri Thanu. Book the Samui to Phangan ferry on 12Go; if your dates hit the full moon, our Full Moon Party guide says whether to go at all. Koh Tao — two hours by catamaran and the only reef in the Gulf worth the fare: a day trip taking in Koh Nangyuan is ฿2,500–3,500 with three snorkel sites, and the speedboat versions leave the most time in the water. Tempted to dive? Our Koh Tao diving guide makes the case for a night or two there instead.
Things to do in Koh Samui: your questions, answered
How many days do you need in Koh Samui?
Four covers the temples, Ang Thong, a market evening, a west-coast sunset and enough pool to justify the flight. Five or six adds a cooking class, the sanctuary and a day on Koh Phangan or Koh Tao. A week makes it a holiday rather than a checklist.
Is Ang Thong Marine Park worth it?
Yes; if you book one boat trip, this is it. Budget ฿1,200–2,500 plus the ฿300 park fee, pick a trip with the viewpoint climb and kayaking, and check the dates: the park closes from about 1 November to mid-December.
What is the best time of year for Koh Samui?
Samui runs on the Gulf calendar, not the Andaman one: February to April is driest, May to September is warm with short storms and good prices, and October to December is the real monsoon, when the boats stop and the waterfalls are at their best. Our best time to visit Thailand guide has the month-by-month picture.
Which elephant sanctuary in Koh Samui is ethical?
The one that lets you walk beside the elephants and feed them, and nothing else — no riding, no shows, no bathing photos. On Samui that is a ฿3,000 half day, worth the money over the ฿1,500 camps by the waterfalls. Read the newest reviews for “ride” or “bathe”; their presence is your answer.
Do you need a scooter to get around Koh Samui?
No, but the island is bigger than it looks and songthaews stop by ten. Grab covers the east and north coasts; a scooter opens up the west coast and the hills, but only with a motorcycle licence or an IDP with the motorcycle category. Without it your insurance is void, and Samui’s ring road has one of the worst accident rates in the country.
