The Smearlagh River is a tributary of the River Feale in North Kerry, Ireland, flowing through a scenic rural landscape before joining the main Feale system near Listowel. As part of the broader River Feale catchment, the Smearlagh offers anglers a genuine Irish river experience, with productive salmon, grilse, sea trout, and brown trout fishing across its length. The river is managed in part by the North Kerry Anglers Association (NKAA), which controls sections of the Smearlagh and offers day tickets to visiting anglers. Roughly 50% of the Feale system — including sections of the Smearlagh — is managed by angling clubs, while the remainder falls under private fishery status, making it essential to seek local advice before accessing any stretch of the river.
