The tide. The hour either side of low and high water are the documented feeding times here, more specific than a generic flooding-tide window. Dawn sessions on a flooding spring tide in summer are the most productive. Baits fished close in catch the bass; baits at distance reach hounds and rays.
Methods. Pulley rig (rays/hounds at distance); Running ledger close in (bass); Lures (bass close in).
Baits. Lugworm (the documented best all-round bait here); Peeler crab (smoothhound on evening tides); Worm and fish baits for general species.
Local knowledge. Two non-obvious notes from regional sources. First, lugworm is named as the best all-round bait here (Visit Arklow / regional guides), not the peeler-crab default many beach anglers reach for. Crab specifically for hounds on evening tides; lug for everything else. Second, Ennereilly South and Ennereilly North fish completely differently: South is shallow sand for bass and hounds, North is shingle with deeper water offshore for flatfish, dogfish and occasional ray. Set bass expectations honestly, typical fish are in the 3 lb bracket with occasional bigger; this is a numbers-of-quality-fish venue, not a 10-lb-specimen venue like Brittas Bay in storm conditions. The Ennereilly River sea trout run between the two beaches can produce takes on lures close to the river mouth in season, a low-pressure bonus opportunity. Quieter and more accessible (parking-wise) than Brittas Bay, with comparable bass fishing on the right night.
