Old Bawn Beach is on the east coast of County Wexford, 5km south east of Ballygarrett Village. The Beach is a 3km section of a long stretch of sandy coastline extending south from Cahore Point and includes part of the Cahore Polders and Dunes National Heritage Area.

The Beach has an easterly aspect overlooking the Irish Sea and is bordered on the west by a line of sand dunes. The area is essentially rural with the nearest major population centre in Gorey Town.
