[6][7] The hill is located close to the NE extremity of Anglesey, and overlooks Llaneilian and the Point Lynas (Welsh: Trwyn Eilian).

[10] An archeologic site named Llys Caswallon, located some hundred metres E of the hilltop, was studied in the 2010s.

[11] The hill summit can be accessed from the village of Pengorffwysfa, at first by an asphalted lane and then following a public footpath.

[12] Mynydd Eilian is part of the Anglesey AONB,[13] and thus some activities or construction works can be restricted because of that.
