How Many Days in Koh Samui? — Trip Planner

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.

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.

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.

Koh Samui with kids, realistically

Choeng Mon and Maenam shelve gently and stay shallow a long way out, which suits toddlers better than Chaweng's steeper drop and jet-ski traffic. Pink Elephant Water Park at Lamai and Paradise Park Farm up in the hills each fill a morning. Samui Elephant Sanctuary retired riding entirely and takes children who can handle mud. Do not put a child on a rented scooter; the ring road is genuinely dangerous.

When the weather turns in Koh Samui

Samui's wet season is October to December with November the worst of it, the opposite of Phuket and the Andaman coast, so a Christmas booking can rain hard. Central Festival in Chaweng is the only proper mall and covers cinema, food court and shops. Cooking schools and massage shops absorb an afternoon cheaply. Sea trips get cancelled outright when the Gulf turns rough, and Ang Thong boats stop first.

When to go to Koh Samui

The month to avoid is August — around 29°C (84°F) with roughly 20 rain days. Prices and crowds track the weather here: March is the sweet spot, August the month most people skip.

Pack for peak season: Summer clothes, plus one light layer for air-con and evenings, High-SPF sunscreen, sunglasses, and a refillable water bottle, A packable rain shell or compact umbrella earns its space, Comfortable walking shoes — every guide on this site assumes you'll use them.

Where to base yourself in Koh Samui

• Chaweng — The long main beach — nightlife, malls, the busiest sand.
• Lamai — Chaweng's calmer sibling — good swimming, Grandma-and-Grandpa rocks.
• Bophut / Fisherman's Village — Boutique-y old town — Friday walking street, wine bars.
• Maenam — Quiet north-shore stretch — long-stay favorite, Phangan views.
