Killiney beach is a long, stony beach offering excellent views of the surrounding rocky coastline including Dalkey Island and Sorrento Terrace to the north, and Bray Head to the south. It is a sheltered location making it popular for walking or swimming with lifeguards on duty during the summer months.
There is also a large green area overlooking the beach which is a popular spot for picnics
The beach has several access points. There is a small car park that can be reached via a tunnel under the railway line from Strathmore Road. A larger pay and display car park is located opposite the Dart station, where there are also toilet and recycling facilities.
