Yasothon does not have an airport but you could fly from Bangkok to Roi Et or Ubon Ratchathani and then hop on a bus.
The closest train stations are in Si Saket and Ubon Ratchathani, located around 100 kilometres to the south and southeast, respectively.
Accessible by frequent buses from Bangkok’s Morchit (Northeastern) terminal along with most provincial capitals within Isaan, Yasothon’s bus station is located on the northern edge of town off Highway 292. Motorbike taxis charge around 30 baht for the three-kilometre ride to downtown. From Yasothon, fares include:

Downtown Yasothon and the Ban Singha old town are both easy enough to cover on foot, although it’s a one- to three-kilometre walk from most hotels to the rocket festival grounds. We saw motorbike taxis at the bus station but nowhere else, and there are no taxis and very few tuk tuks.
A car rental spot at the old bus station off Rattanaket Road was closed when we passed through on a Sunday, and we found no motorbike rental in Yasothon. If wanting a vehicle you’re probably best off renting in Ubon Ratchathani.
