The northern part of Malahide Estuary in Dublin is accessed quite some distance from Malahide. You need to travel towards Donabate, coming from Swords direction. Don’t take the turn into Donabate, but shortly after take a left turn towards the Island Golf Club. Stay to the right as you pass the entrance to the Island Golf Club, there is a parking area overlooking the estuary. The beach is called Corballis Beach.
This is a tidal estuary and large areas of the mud flats are exposed at low tide. There are several channels of water visible at low tide and they contain a large variety of seabirds. You can walk along the beach at low tide as far as Malahide. It is about a 30 minute walk.
The golf club borders the beach and you can see a variety of finches, chats and pipits. Sat Nav co-ordinates for the car park are 53.466313, -6.135043 or you can enter “The Island Golf Club” into Google maps and drive past the entrance to the parking area.
The other side of the estuary is accessed from the town of Malahide.
