About Mullaghanish [Mullach an Ois]

This prominent Derrynasaggart peak is dominated by a towering broadcasting mast, visible across much of Cork and Kerry. While a paved service road offers a straightforward ascent from near Ballyvourney, the summit provides a rugged vantage point overlooking the distinctive Paps of Anu and the rolling Boggeragh Mountains to the east.
