Mountashton
Dún Laoghaire–Rathdown / 81 properties
A residential townland on the slopes above Killiney, Mountashton benefits from the elevated position that characterises the coastal suburbs between Dalkey and Shankill. The housing has developed over successive decades, and the terrain gives many homes views toward Dublin Bay and the Wicklow Mountains. Killiney DART station and the coastal walks provide transport and amenity, while the hillside setting lends the area a quieter character than the busier coastal road below.
