Koh Phangan is most easily accessed via Koh Samui Airport though it is slightly cheaper to fly to the regional transport hub of Suratthani. From Koh Samui a fast boat takes only 30 minutes whereas the journey from the mainland takes around eight times longer. If you come overland, the overnight train is the best option with a first class sleeper carriage ideal for families. Buses are the most economic choice with a trip from Bangkok costing only about 650 Baht, all the way to Koh Phangan. Ferry services are more or less hourly throughout the day from Koh Samui and every couple of hours from the mainland; several boats also go regularly from Koh Tao.
