Booterstown Marsh is a small wetland just in from the coast. It is used both as a roosting site for waders and gulls at high tide, but also by more freshwater species such as Snipe and Water Rail.  It is on the left side of the road going from the Merrion Gates towards Blackrock. It can be viewed from the carpark at the railway station but sometimes better views can be had from the path that runs along the main road.  A channel runs along the entire length of the seaward side of the marsh, and this can be good for Kingfisher in winter. The small reedbed directly below the main road has Water Rail throughout the year and the small channels and pools are good for Snipe in winter.

Birds found at Booterstown
From autumn to spring the marsh attracts small numbers of Teal, Wigeon Snipe, Black-tailed Godwit, Bar-tailed Godwit, Whimbrel (spring & autumn), Curlew and Redshank. It is one of the few sites in Dublin for seeing Water Rail while Kingfishers are regularly seen in winter. It is also often used by Little Egrets and is a favoured roosting site for gulls at high tide.
