The closest train stations are found in Nakhon Ratchasima (Khorat), 60 kilometres south of Phimai.
Khorat’s Bus Terminal 2 is the only place where you can catch a bus direct to Phimai: they depart every half-hour from 05:00 to 22:00 for 50 baht and take an hour. In Phimai, the last bus to Khorat departs at 18:50.
Phimai’s tiny bus station is located two kilometres west of the historical park off Highway 206, but buses also drop off and pick up at the clocktower in the centre of town. Songthaews and motorbike taxis are available at the bus station.
Heading north from Phimai is trickier, but doable. You can pay a songthaew driver 150 baht at Phimai Bus Station, or a motorbike taxi around 100 baht, for a private trip to a junction at Talad Kae where buses running to Khon Kaen, Udon Thani and Nong Khai pick up passengers. If coming from any of these destinations, ask to be dropped at Talad Kae and then catch a local bus or motorbike taxi to Phimai.
Take a bus to Khorat and make a transfer if you’re heading to Bangkok or anywhere else in Thailand.
Phimai is perfect for walking or pedalling. Bicycles can be rented at Boonsiri Guesthouse for 70 baht and both Phimai Paradise properties for 100 baht. Motorbikes can be rented for 300 baht at New Motorbike on Anantajinda Road (look for the huge red Honda sign), just west of the bridge on the left and a kilometre west of the historical park. It closes on Sundays.
Cheap public songthaews cruise between the bus station and clocktower. It’s possible to hire a songthaew for a private day trip, but most drivers speak minimal English. The tour service at Moon River Resort is probably a better option.
