The 184-metre (604 ft) high hill stands 4 km west of Dingle in an isolated position in the short peninsula dividing Dingle Harbour from the Atlantic Ocean.

[citation needed] The top of the hill hosts the Eask Tower, a solid stone tower built in 1847.

[4] The English meaning of Cnoc na Ceathrún is hill of the quarter.

[5] The walk which leads up to the summit takes 1.6 km from the asphalted road.

Due to the very interesting panorama it's advisable to choose a clear day for it.
