Rayong is the eastern gateway to the north and northeast of Thailand. As such, there are many regular bus services connecting Rayong and Bangkok and other provinces such as Chiang Mai, Nakhon Ratchasima, and Nong Khai. Busses from Bangkok to Rayong depart regularly from Ekkamai eastern bus terminal (near BTS Ekkamai). There are specific busses for those who wish to go to Koh Samet that terminate at Ban Phe opposite the boat pier.
