Listowel is on the N69 Limerick - Foynes - Tralee road. Bus Éireann provides daily services to Tralee, Cork, and Limerick. The nearest railway station is Tralee. Listowel used to have its own railway station on a broad gauge line between Tralee and Limerick city, however this was closed to passengers in 1963, freight in 1978 and finally abandoned and lifted in 1988. The station building has been preserved as a private residence.
