FOR ANGLERS

Planning a fishing visit

IFI organises its Shannon guide around angling centres including Athlone, Banagher and Carrick-on-Shannon, with separate entries for river stretches, lakes and backwaters.

Species described by the official guide: Bream, Roach, Tench.

Choose the named water in the guide: permit arrangements for the Suck and Inny are separate from those for the main Shannon.

Current rules, licences, permits and access

A State licence and permission for a particular fishery are separate matters. Check the applicable licence requirements, the current rules for your species and water, and the club or rights holder’s permission. A permit does not by itself establish a route across private land.

These links lead to the official publisher. Seasons, restrictions, prices and access arrangements are not reproduced here.

Check current rules, permissions and local access before travelling. These readings do not measure fishing quality or establish that it is safe to enter the water.
