Why fish Flounder at Killoughter Beach
Reputed best Wicklow beach venue. Specimen homelyn, thornback, smoothhound and bullhuss in the catch record.
A shingle beach in the heart of the Greystones-to-Wicklow shingle belt.
Documented in the Eastern Regional Fisheries Board guide as the regard of many anglers as the BEST of all the Wicklow beach venues, the beach turns up quality fish with regularity.
Specimen-class homelyn ray, thornback ray, smoothhound, bullhuss and occasional spurdog have all been recorded here.
Short: Reputed best Wicklow beach venue.
Specimen homelyn, thornback, smoothhound and bullhuss in the catch record.
Estuaries, sandy beaches, muddy creeks and shallow inshore ground, especially around river mouths and drainage outflows.
Reputed specimen beach for rays and hounds on spring nights, not a beginner mark.
The Eastern Regional Fisheries Board guide explicitly states 'many anglers regard Killoughter as the best of all the Wicklow beach venues' on the basis that it produces quality fish with regularity.
Specimen-class homelyn ray, thornback, smoothhound and bullhuss are all in the catch record, this is a serious species venue, not a casual beach.
Two practical local notes: (1) the road in is poor, and (2) weed can shut the beach down after onshore wind, one SAI session was abandoned for that reason and turned out to be the wrong call (the weed cleared shortly after).
Pair this mark with Five Mile Point and the Breaches as a Newcastle/Killoughter cluster, the same shingle belt with different micro-features.

Size and identification
Typical shore size around 200 to 400 g from Wicklow beaches and estuaries; specimen class from about Fish over 700 g are notable shore flounder.
Brown or grey-brown upper surface with orange-tipped spines along the lateral line. Eyes on the right side. Can develop reddish blotches, easily confused with plaice but lacks the vivid orange spots. The rough, prickly lateral line is the key identification feature.
Tip: Flounder are suckers for movement. Slowly dragging your bait across the bottom and pausing it triggers far more bites than static fishing. In estuaries, cast uptide and allow the bait to trundle downtide, the disturbance in the sand draws flounder in.
Irish shore context: record class around 2.71 kg.
