Killiney Hill Park is immediately surrounded by Dalkey, Killiney, Ballybrack and Loughlinstown. It is easily accessible from Dun Laoghaire, Blackrock, Sallynoggin, Glenageary, Deansgrange, Cabinteely and Shankill and by pedestrians from the local DART stations at Killiney and Dalkey at each end. Dun Laoghaire Ferryport, one of the main tourist gateways to the country, is very close by.

There are quite spectacular views from the park, over the city, the bay, and the Dublin and Wicklow mountains. Killiney Bay is said to resemble the Bay of Naples and this comparison is reflected in local Italian-sounding names: Vico, Sorrento Terrace, Monte Alverno, San Elmo, Capri. In 1987 extensive reconsruction of the park's infrastructure, including the granite tower portion of the Tea Rooms, took place with the aid of a grant from the Department of the Environment.

The Park's topography is quite dramatic. Its highest point, at the obelisk is 170m above sea level. The steepest slopes are on the Eastern side, embracing the curve of Killiney Bay. Slopes on the Western (landward) side are more gentle except in Dalkey Quarry where sheer 30-40m high cliffs enclose flat, sheltered areas at road level.
