Most people departing Bangkok for Pattaya travel by bus. It is possible to get a bus directly from Suvarnabhumi Airport to Pattaya or from Bangkok’s Ekkamai Eastern Bus Terminal.
From the Eastern Bus Terminal (next to the BTS Ekkamai station, opposite Sukhumvit Road soi 63) there are bus departures throughout the day, leaving approximately every thirty minutes from around 5 am to nearly midnight. These air-conditioned busses cost just over 100 baht for a one way ticket and complete the journey from Bangkok to Pattaya in around two hours.
From Bangkok’s Mo Chit Northern Bus Terminal and the Sai Tai Mai Southern Bus Terminal (Sai Tai Mai), buses leave less frequently throughout the day, but at similar cost and travel time as those from Ekkamai.
If your final destination is Jomtien Beach it may be preferable to get a 2nd class bus rather than the 1st class busses mentioned above, as many 2nd class busses continue on to Jomtien thus saving you the time and hassle of arranging a transfer from North Pattaya Road bus station. The bus station for the 2nd class buses is on South Pattaya Road.
From the Northeast (Isaarn) and the NorthThere are direct air conditioned buses from Nong Khai, Khon Kaen and Nahkorn Ratchasima (Khorat) to Pattaya. From other northeastern towns it’s best to get a bus to Ratchasima (Khorat) and then buy a ticket from there to Pattaya.
From Chiang Mai and Mai Sai there are direct busses to Pattaya.
