Things to Do in Koh Samui

About Koh Samui

Koh Samui sits in the Gulf of Thailand, where hills meet beaches and Buddhist temples overlook the coast. The island mixes quiet island living with upscale resorts, coconut groves with yacht marinas. You'll see fishing villages alongside five-star properties. Monks walk through villages each morning. Temples echo with evening chants. Locals practice sanuk—the Thai art of finding joy in small moments. The island runs on beach time. Waterfalls hide in the jungle interior, while curry vendors set up at beachfront markets serving proper Thai food. Spas offer ocean-view treatments if that is your thing. Longtail boats share the bays with expensive yachts, which tells you everything about who visits. Old coconut plantations still cover parts of the island, their shadows stretching across the sand. The beaches are clean—for now. Koh Samui won't overwhelm you. It doesn't try to be Phuket or Bangkok, and that is the point.

Travel Tips

Transportation: Rent a scooter (150-300 baht/day) for ultimate island flexibility, but avoid the dangerous Ring Road during rush hours. Songthaews (shared red trucks) cost 50-100 baht for most journeys. Always negotiate taxi fares beforehand – expect 300-500 baht for cross-island trips.

Money: ATMs are widespread but charge 220 baht foreign transaction fees. Bring cash for local markets, street food, and small establishments. Credit cards accepted at hotels and upscale restaurants. Exchange money at banks for better rates than hotel counters.

Cultural Respect: Cover shoulders and knees when visiting temples; remove shoes before entering. Avoid pointing feet toward Buddha statues. Don't touch anyone's head or point with your feet. Show respect during the 6pm national anthem when it plays in public spaces.

Food Safety: Choose busy street stalls with high turnover for freshest food. Avoid raw vegetables and tap water. Stick to bottled or boiled water. Fresh fruit you peel yourself is generally safe. Local favorites like som tam and grilled seafood are usually reliable at popular spots.
