The seaward side of the railway causeway running north from Malahide village is very similar to the outer estuary at Rogerstown. Immediately west of the railway is a good place to see Merganser, Goldeneye and Great-crested Grebe.

At the Swords end of the estuary a new elevated motorway bypass of the existing Swords bypass has been built. It traverses the extreme west end of the estuary and it remains to be seen if it will be detrimental to the bird life there; hopefully not.

The area near this flyover is shallow with grassy islands. In Autumn it is good for passage migrants like Curlew Sandpiper, Ruff, Spotted Redshank and Little Stint. In winter it teems with Lapwing, Golden Plover, Redshank, Curlew, Black-tailed Godwit, Snipe and Dunlin. Little Egret and Mediterranean Gull are always possible and it has seen many rarities lately including American and Pacific Golden Plover and Long-billed and Short-billed Dowitcher.

The bridge at Spittal Hill on the Ward River is a great spot for Kingfisher. The seaward side usually has some Little Grebe as a bonus. Continue along to Hutchinsons Strand and feed the very tame Mute Swan which congregate there.
