Surin doesn’t have an airport, but Nok Air offers transport to/from Bangkok through its “Fly and Ride” service. In Surin, a minibus picks up passengers at the Majestic Hotel and drives them to catch a daily flight out of Buriram airport.
Surin is a main stop on the Northeastern line.
In Bangkok, trains depart at 05:45, 06:10, 10:05, 15:20, 18:55, 20:30, 21:50 and 22:25, arriving in Surin around nine hours later.
In Surin, trains return to Bangkok at 05:20, 07:55, 09:40, 11:30, 16:40, 19:30, 20:25, 21:00 and 22:00.
Fares range from 73 baht for a hard third class-seat up to 350 baht for first class, and some trains have sleeper options. These trains stop in Buriram, Nakhon Ratchasima (Khorat) and Pak Chong (Khao Yai).
In Surin, trains continue east to Si Saket and Ubon Ratchathani at 00:30, 03:20, 04:30, 05:40, 07:00, 09:40, 12:10, 13:45, 15:10 and 17:20.
Surin’s bus station is conveniently located to the east of Jitrbumrung Road and within walking distance of the train station. Fares include:

Surin is fairly small and easy to cover on foot, but there are an almost ridiculous number of tuk tuks, motorbike taxis and samlors all vying for business. Pink songthaews also run in loops along the major roads and stop at the bus station and train station. A shortish ride within the city centre should set you back around 40 baht for a tuk tuk or 30 baht for a samlor.
Farang Connection (the restaurant just east of the bus station) rents out motorbikes for 300 baht for one day or 250 baht for two or more days, and they can also arrange car rentals. Alternately, Mr Pirom at Pirom-Aree's House can help arrange a motorbike rental from a shop in town.
Orange songthaews running to outlying provincial towns can be caught at the bus station. Destinations are listed only in Thai but someone will doubtless ask where you're going and put you on the right truck. Local buses or minibuses service most provincial destinations that will be of interest to travellers, like Baan Ta Klang, Sikohraphum and Chong Jom.
