What's actually worth your time in Koh Samui
Wat Plai Laem, with its eighteen-armed Guanyin standing over an artificial lake, rewards more time than the Big Buddha at Bang Rak, which is free, twelve metres tall and effectively a car park beside the pier. Hin Ta and Hin Yai at Lamai are a five-minute stop and an anatomical joke. Ang Thong marine park, a couple of hours west by boat, charges foreigners three hundred baht and swallows a whole day.
What to eat in Koh Samui
Hua Thanon on the southeast coast is a Muslim fishing village whose morning market sells the island's best seafood and southern curries to almost no tourists. Nathon's market before nine is where cheap breakfast lives. The Friday walking street at Fisherman's Village in Bophut trades from about five until ten. Southern Thai cooking means sour turmeric gaeng som, and coconut in nearly everything, since Samui grew coconuts long before it grew hotels.
What things cost in Koh Samui
A scooter rents for roughly 140 to 350 baht a day depending on season and shop. A plate of something at Nathon or Hua Thanon market runs sixty to a hundred baht, while a Chaweng beachfront restaurant multiplies that several times over. Ang Thong charges foreigners three hundred baht on top of the boat fare. Flights in are expensive because Bangkok Airways owns the airport, and the Donsak ferry undercuts them heavily.
What first-timers get wrong in Koh Samui
No taxi here runs a meter, so the fare is whatever you agree before the door shuts; songthaews on fixed daytime routes cost fifty to a hundred baht. Police checkpoints ask for an International Driving Permit and the standard roadside settlement without one is around five hundred baht. Photograph a rented scooter from every angle before riding off, and leave a cash deposit rather than your passport.
Koh Samui's museums, and which one to pick
Samui has no museum worth the word, which is worth knowing before an itinerary depends on one. The nearest thing is Wat Khunaram on the ring road, where Luang Pho Daeng, who died meditating in 1973, sits upright in a glass case wearing sunglasses. Nathon's waterfront row of Chinese shophouses is the only surviving pre-tourism architecture on the island. Almost everything else was built after 1975.
