Which terminal do I board at?
Board a service to Donsak - KohSamui at Sai Tai Mai · Southern Bus Terminal. Show your taxi or app driver both สายใต้ใหม่ and Borommaratchachonnani Road. If using rail, consider continuing by vehicle from a station such as Bang Wa. Do not assume there is a direct walkable interchange from the rail station to the terminal.
Distinguish Sai Tai Mai, the new Southern Bus Terminal, from the old southern departure area near Pinklao. Some southbound buses originate at Mo Chit 2 and call here, so the original departure time in search results is not necessarily your boarding time at Sai Tai Mai.
