How to Get to Koh Samui 2026: Flights, Ferries & Getting Around
Key Takeaways: There are 2 ways to get to Koh Samui: fly directly to Samui Airport (USM) or take a bus/train to Surat Thani then a 2.5-hour ferry. Flights from Bangkok take 1 hour from 1,200 THB ($35+). The Bangkok Airways monopoly on the airport makes direct flights 2-3x more expensive than flying to Phuket. Budget option: fly Bangkok to Surat Thani (~400-600 THB), then ferry (~300 THB, 2.5 hours) = ~700-900 THB total vs 1,200-2,500 THB by direct flight. International visitors fly via Bangkok (BKK/DMK) or Singapore.
[ORIGINAL DATA] Bangkok Airways operates the only commercial flights into Samui Airport (USM). This monopoly means direct BKK-KSM fares rarely drop below 1,200 THB and peak at 4,000+ THB in December. AirAsia and Thai Lion Air fly to Surat Thani (URT), 1.5 hours from the ferry terminal. Budget travelers who route via Surat Thani save 400-1,500 THB on flights at the cost of 3 extra hours of travel.

Getting Around Koh Samui
Scooter Rental (Recommended)
Cost: 150-200 THB/day
Best for: Independent travelers, couples, those staying 3+ days
Renting a scooter is the best way to explore Koh Samui. The ring road circles the island in about 1 hour. Waterfalls, temples, secret beaches, and hidden viewpoints are all accessible only by scooter or private car. Rental shops are everywhere — look near your hotel or at any of the main beach roads.
Requirements: An international driving permit (IDP) is technically required. In practice, enforcement varies, but travel insurance that covers scooter accidents requires a valid license.
Songthaew (Shared Taxi)
Cost: 50-150 THB per trip depending on distance
Routes: Run along the main ring road connecting all beach areas
Songthaews are the local minivans that function as shared taxis. Flag one down on the ring road, tell the driver your destination. No meters — agree on the price before getting in. Cheaper than Grab for short trips on main routes.
Grab (Rideshare)
Cost: 150-350 THB for typical trips
Coverage: Good in Chaweng, Lamai, Bophut; limited in remote areas
Grab is available on Koh Samui and is the most reliable option for airport transfers or late-night rides. Download the app and get a Thai SIM card at the airport (AIS tourist SIM: 299 THB).
Taxi
Cost: 350-600 THB typical trips
Airport to Chaweng: ~350-450 THB (fixed rate)
Official taxis at Samui Airport have fixed rates posted at the stand. For non-airport trips, use Grab instead — metered taxis are uncommon and negotiated taxis vary widely.
