[7] From the summit, which is called Fairy Castle,[3] there are views of much of the Dublin area from Tallaght to Howth to the north while Bray Head, Killiney Hill, the Great Sugar Loaf and the Wicklow Mountains are visible to the south.

[13][14] In an area of forest to the southeast of the summit, near Ballyedmonduff, at grid reference O 185 213, there is a Bronze Age wedge tomb, known as the "Giant's Grave".

[15] It is considered one of the finest examples of a wedge tomb in Ireland:[16] the antiquarian John O'Donovan said of it, "I doubt I have met so perfect a pagan grave in any other counties hitherto examined".

[19] In addition, the pine forest that now surrounds the site obscures the views of the Great Sugar Loaf mountain and the twin tors of Two Rock that would have been possible from this location in the past.

[21] However, when John O'Donovan visited on behalf of the Ordnance Survey, the locals told him that ashes had been found when the grave was opened.

[18] The tomb consists of a burial gallery over 6 metres (20 feet) long divided into three chambers surrounded by a horseshoe-shaped arrangement of stones with a straight façade at the western end.

[27] Two Rock can be reached via the Coillte-owned forest recreation areas of Ticknock,[28] Kilmashogue[29] and Tibradden,[30] which are managed by the Dublin Mountains Partnership.
