[6] Diamond Hill lies just west of Knockbrack and the small massif of Benbrack, and looks into the Polladirk valley, around which several major Bens are located.

[7] Despite its moderate size and isolation, compared to the nearby Twelve Bens, Diamond Hill is a popular peak due to its paths and boarded mountain trail, and relative ease of access, together with views of the core Twelve Bens range, and western Connemara.

[8][6][3] According to Irish academic Paul Tempan, "Ghuaire" most likely refers to Guaire Aidne mac Colmáin (died 663), one of the Kings of Connacht and a member of the Ui Fiachrach Aidhne.

To the west of Diamond Hill is the Ballinakill harbour (and weather permitting, views to the isles of Inishboffin and Inishark), and to the south are the western boglands and dotted lakes of Connemara.

[3][10][7] Diamond Hill is popular for its accessibility and panoramic views,[11] only ranking behind Croagh Patrick for footfall,[8] and attracts both Irish walkers and foreign tourists.
