To go from Koh Samui to Koh Phangan you will need to catch one of the many ferries that make this journey. Ferries leave Koh Samui from the following piers:
Big Buddha (Northeast Samui) –> Haad Rin (Phangan)
Bo Phut (Northeast Samui) –> Thong Sala (Phangan)
Nathon (West Samui) –> Thong Sala (Phangan)
Maenam (North Samui) –> Thong Nai Pan (Phangan)
Journey times vary from between 30-50 minutes, depending on which ferry you choose. Routes and timetables are subject to change based on time of year and weather conditions so be sure to check before planning your trip.
The piers all have cafe/bars that are open and serve food and drinks while you wait to board the ferry. Journey’s can be rough during the monsoon seasons, so bring your sea legs at these times.
